Yamaha YZF-R1 in the 50,000 km endurance test

Loved, hated, definitely expensive

The Yamaha YZF-R1 has passed the MOTORCYCLE endurance test. It took her almost 3 years to cover the 50,000 km. Here you can read how the Japanese sport bike fared.

It usually takes almost two years for an endurance test motorcycle to have 50,000 kilometers on the clock. Tea YIt took amaha YZF-R1 around three years to cover this distance. However, this is not atypical for a super sports car – the Ducati 1199 Panigale also needed almost exactly three years in our long-term test fleet to reach 50,000 kilometers.

As an uncompromising athlete, the R1 divided its riders into two camps right from the start. There were her ardent followers, who loved her for this sportiness, and those who held that against her. There was nothing in between. It just left no one cold.

Coupling exchanged twice

Tobias Wassermann

The clutch had been replaced twice by the halfway point of the test.

As soon as the R1 was in the long-term test fleet in May 2015, it started. The driver’s log was enthusiastic about the great stability and greed for curves, one line further from the largely lack of suitability for everyday use. Too sharp engagement of the clutch, too little torque at the bottom, too long first gear. Some loved them for their sportiness, others scourged them for precisely that. Unimpressed by this, she reeled off her test kilometers. Incidents up to the first inspection at 10,000 kilometers: None, apart from the constant nagging about the clutch. It was only at 11,383 kilometers that she ordered an unscheduled recall to the workshop to exchange the transmission. On the occasion, the clutch linings were also replaced, which until then had repeatedly aroused displeasure due to sharp, poorly metered engagement.

Then it went on to eat the kilometers. The calm lasted only a shorts time, just a few thousand kilometers later the clutch began to make itself unpopular again with the familiar symptoms. Which is why the clutch was completely replaced under warranty at 23,300 kilometers.

Battery weak

Which took care of the clutch issue – for now. The winter that set in shortly afterwards brought the classy athlete into other hardships after frosty nights. Starting the engine in the morning required a great deal of sensitivity: when starting the engine, just don’t accelerate and after starting it is best to let it run for a few seconds in peace and quiet, was the recipe. Anyone who stalled the R1 when starting with a throttle that had to be explored or because of the engaged clutch, sometimes had a hard time bringing the R1 back to life. The weakly dimensioned battery did not allow many start attempts before it ran out of juice.

After 26,300 kilometers, the small power storage unit was due for replacement, along with the rubber shock absorbers on the rear wheel, fork seals and chain set.

Strange performance loss

Rainer Froberg

In search of the missing performance.

Immediately afterwards there were big eyes in the course of the exhaust test for the interim balance, because of the original 197 hp, the R1 only brought 190 to the test bench role. The whereabouts of the remaining seven horses was a mystery. Since the extensive troubleshooting was unsuccessful, seven missing horsepower in everyday life really do not play a major role and the R1 ran mechanically clean, the test was continued. So the R marched straight to the end of the endurance test without any abnormalities, you can see from, you guessed it, the recurring nagging about the clutch. However, they must not obstruct the view that the R1 otherwise performed its service for 15,000 kilometers without any problems, often also in the unpopular professional traffic. Freshly back from the 40,000 inspection, we went on an autumn drive. But it left a dull impression and tester Georg Jelicic complained about a lack of performance after a brisk stretch on the Autobahn. Back in Stuttgart, up to the test stand, disillusionment: only 179 hp were on the record. The hectic pace was great, also at Yamaha. Sensors were exchanged, error memory read out – without success. The only thing left was to inspect the R1 at the importer’s workshop. They promptly struck gold there. During the 40,000 inspection, the correction of the valve clearance is on the agenda for the first time. The authorized workshop had apparently reinstalled the intake camshaft, twisted by a tooth – the explanation for poor starting behavior and low performance, which now really cannot be blamed on the classy R1.

And a mistake that could easily have resulted in major damage. Confident in the robustness of their engine, Yamaha gave the green light to continue the test after correcting the timing. The R1 rewound the remaining 6,000 test kilometers unmoved.

Robust interior

During the final measurement of the performance, the R1 was there like a penny and even a tad faster than at the beginning. On the test bench, on the other hand, with 187 hp it only just delivered the performance as in the interim results. The pressure loss measurement, however, was quite reasonable and did not suggest either wear or defects. So what would come to light when you disassemble it? First of all, the combustion chambers, ducts and piston heads are amazingly clean. Only minimally widened valve seats and tight valves with dimensionally stable stems. Except for a tiny superficial score on one of the piston skirts, the pistons and liners look flawless.

The piston pins are all true to size, despite traces of wear on the DLC (diamond-like carbon) coating. Main and connecting rod bearings show a normal running pattern, all running layers are intact. The bearing pin contact pattern is also okay. However, Yamaha does not specify any wear limits for main and connecting rod bearings, only installation tolerances. And the warehouse clearance is just above what, strictly speaking, could be rated as "worn out". However, the measured bearing clearances are not critical. For the main bearings, for example, the upper tolerance limit is 0.045 mm, while the bearing clearances are 0.05 mm and the outer bearing on the alternator side is 0.06 mm, which in itself is still within limits. As a result, and due to their optical condition, the bearings would not really be ready for scrap and would be good for many more thousands of kilometers. However, since the engine is open, we would exchange them in this process.

Noticeable 2nd gear

Jacek Bilski

Clear marks on the 2nd gear wheels.

The distance left clear traces on the 2nd gear wheel, which incidentally was the reason for the recall and replacement of the gear at the time. Apparently it is used excessively as a driving gear in everyday life due to the torque curve and translation and may not really be designed for this load. Otherwise, the transmission is in almost perfect condition, even the shift forks show only the slightest marks.

The clutch, already the third copy and only just under 27,000 kilometers old, is in good condition apart from minor pressure marks from the springs in the pressure plate. Possibly they are a piece of the mosaic of the criticized dosability. Although Yamaha are apparently not aware of any customer complaints about the clutch function.

The rest of the engine innards show at best the mileage appropriate to the mileage, such as the rotor of the oil pump or the selector shaft.

A good certificate can also be issued for the build quality of the R1. Screw connections, plugs, surfaces of frames and chassis parts can be seen even after three winters. Only one screw on the side stand was permanently rusted after three years of salt and spray water bombardment. The brake discs, on the other hand, show wear. The two front ones are still two tenths of a millimeter above the wear limit of 4.5 millimeters, the rear one already a tenth below. However, the front wheel bearings were ripe for replacement.

R1-driving is nothing for bargain hunters anyway. Even if she was careful with brake pads and drive chains and an average consumption of 6.7 liters is a lot, but still within limits for such a projectile.

Bad cost balance

Hertler

The R1 burned fuel for almost 3,700 euros over the test distance.

The inspections that are due every 10,000 kilometers tore a bigger hole in the budget. While the first went for a moderate 332 euros, the following two had to dig a little deeper into your pockets at 525 and 556 euros. The 40,000-series maintenance was really tough, when the valve clearance control was on the agenda for the first time and which cost a hefty 1,200 euros.

It has always been a little more expensive to have a special taste. And when it comes to driving fun, the R1 is really something very special for sports fans. In addition to the one-off refusal to start in the morning, it is primarily the cost balance that causes the R1 of the current year to fall behind in the ranking compared to its namesake, which was already tested in 2008. Only the unexplained and unsatisfactory clutch behavior and the noticeable second gear tarnish the otherwise mechanically solid performance of the crossplane four-cylinder.

Balance after 50,000 km

Cylinder head: There are remarkably few deposits in the combustion chambers. The valve seats are hardly widened, all valves close tightly. Valve stems and guides are all true to size. The same goes for the camshafts, which, like the rocker arms, are inconspicuous.

Cylinder / piston: The piston and cylinder are dimensionally accurate and have only minimal signs of wear. A piston skirt shows a score, overall very little oil carbon deposits.

Crank drive: Connecting rods and main bearings show tracks corresponding to the mileage. Your bearing play is slightly outside of the installation tolerance.

Power transmission: Clear wear marks on the second gear wheel on the transmission input shaft. Shift shaft and forks are perfect, clear pressure marks of the clutch springs in the pressure plate, timing chain tensioner with slight traces of running.

Frame / chassis: The paintwork and surface coatings are in good condition, rocker arms, swing arm and steering head bearings are free of play. Side stand retaining screw rusted tight, front wheel bearing defective, rear brake disc below wear limit.

Yamaha takes a stand

Yvonne hertler

The Yamaha ambassadors Ralf Keller (2nd from right) and Karlheinz Vetter (right) were very satisfied with the result.

… to the grooves on the oil pump: The grooves are completely harmless to the mileage. Assemble and move on.

… to the tracks on the second gear wheel: The second is one of the most heavily used gears on a motorcycle like the YZF-R1 because the second is used very often. We wouldn’t switch it as it isn’t pitting.

… to the minimal grinding marks on a shift fork body: We cannot explain these at this point, but in any case without hesitation.

… to the tracks on the coating of the piston pins: Minimal wear, completely harmless. Assemble and move on.

… on starting difficulties and replacing the battery: These occurred primarily in winter. The R1 is definitely not the predestined winter motorcycle. Most motorcycles are mothballed in winter. For reasons of weight and space, the battery is chosen to be relatively small, so that it can reach its limits in sub-zero temperatures. We recommend charging the new battery carefully and "learning it."", so that it has its optimum performance.

… to swap the clutch twice: From our market observation we have no abnormalities in this case; the wear could be due to increased use of the clutch due to the long 1st gear.

… to the coupling function: Again, there are no anomalies from the market.

… to the main and connecting rod bearings outside of the installation tolerance: The problem that Yamaha does not give any wear dimensions is actually something that we regularly encounter in endurance tests. The way they looked, you can put them back in and continue driving without hesitation.

Reading experiences

Moritz Westenberger

Reader Moritz Westenberger loves his R1.

Here is a short summary of my R1M: approval May 2015, then initial inspection. Recall exchange 2nd gear. Criticism 1: Multiple visits to the workshop, as the battery is permanently discharged and even with the charger connected, the battery cannot start up after two weeks of idle time. Pushing is almost impossible and it takes at least 10 minutes to get to the battery. Criticism 2: The clutch grabs and is difficult to dose when starting. Criticism 3: performance characteristics (everything from 7000 rpm) for everything besides the racetrack ugly. Criticism 4: The temperature is permanently too high, especially when driving on the racetrack, for example after a few fast laps in Hockenheim (1.54 min), after rolling out in the pits always over 120 degrees. As far as I know, the piston crown cooling has also been changed in the meantime. Neutral point: Front brake (I still drive HP4 and ZX-10R, built in 2016) not good in comparison. Plus point: ingenious chassis (top handling, feedback, stability). I traded in the machine with 3,600 kilometers in January 2018.

My RN32 (first registered in May 2015) has now accompanied me for almost 20,000 kilometers of track and country roads in a species-appropriate driving style. First of all: It’s beautiful, the sound is breathtaking (not standard), the seating position, the handling – for me as a hobby racer the perfect bike. I would buy them again in a heartbeat! Sure, it’s not my first choice for normal everyday use. Not even for travel or the like. But that’s not what it’s made for. So far there has been an unscheduled visit to the workshop: Callback, gearbox exchange. The only defect that caused (starting) problems was the battery. This was defective after 1.5 years. A lithium-ion battery is a good alternative! Otherwise she drives and drives and drives. The operating / maintenance and servicing costs are sporty. With a brisk driving style, I add an average of 0.5 l / 3,000 km of engine oil. No – there is nothing, simply nothing to complain about. To be recommended without reservation.

A leaky fork seal on the right handle required an exchange. In addition, the front brake now seems a bit toothless. At low temperatures, the steering damper is a bit tough.

45,700 km: In the final spurt

Hardly out of the workshop, it went on an autumn drive, where the R1 was attested to be lousy starting and cold running behavior – pushing included thanks to the weakly dimensioned battery. Later, after a brisk drive on the motorway, a performance-spoiled pilot complained of losing it. Which the test bench later confirmed. This was followed by a long troubleshooting process that ultimately led to the importer in Neuss. There it turned out that the inlet camshaft was installed offset by one tooth after the valve clearance had been adjusted. Fortunately, the pistons and valves still had enough space, and after the correction the R1 runs again as usual.

Mileage: 42,000, 10/2017

At a mileage of 42,000, the Yamaha YZF-R1 has to undergo a major inspection with valve clearance control. This is an undertaking which, due to the tightness, has the character of detention and is estimated at 32 work values, i.e. 192 minutes of working time. On the occasion, the front light unit was also replaced, as one of the lenses had a crack. Whether rockfall or stress cracks remained unclear, in any case the unit costs just under 1,000 euros plus one hour of assembly time. Without the headlights, the cost of the inspection was still 1,200.85 euros.

Don’t complain, work!

Mileage: 32,540, 4/2017

In connection with the endurance test interim balance in MOTORRAD 14/2017, the editors also felt retrofitting exhausts on the tooth. It turned out that the Yamaha YZF-R1 had lost six hp compared to the initial measurement at the beginning of the test: Now it still pushes 191 instead of a more powerful 197 hp.

Error messages occurred on the dynamometer: For the on-board electronics, it is implausible that the rear wheel 280 moves while the front wheel is stationary. However, the error could be deleted by means of system diagnostics at the dealer. The minimal reduction in performance of three percent remained.

However, it only takes effect from 9,000 rpm, so it only comes into play on race tracks or empty motorways. Nevertheless, the R1 was then inspected and measured again at the German Yamaha importer. First result: no major discrepancy between the two different test stands. The MOTORRAD copy is therefore well calibrated. Second result: Well?!

Pressure loss and compression measurements of the R1 long-term test engine show good, inconspicuous values. One suspicion: As part of the official recall, the R1 received a completely new gearbox – the input measurement was carried out before the replacement. This means that increased friction of the new parts in the second transmission may have an effect.

Mileage: 30,000, 3/2017

In the end the jerking got stronger again, but this time the dealer identified a different cause: the connecting webs of the shock absorbers in the rear wheel hub were broken. Therefore, there were now new rubbers at the 30,000 inspection.

Keyword rubber products: The slightly leaking Simmerrings of the upside-down fork had to be replaced. The brake fluid was also changed, which had a noticeable effect: The front brake now shines again with a clear, precisely controllable pressure point. "Now the R1 feels dewy again", shortly thereafter is a happy comment in the logbook.

Mileage: 26,373, 11/2016

The Yamaha YZF-R1 is currently causing a little deeper worry lines. On the occasion of the upcoming interim endurance test, the Akrapovic muffler from the Yamaha accessories program should give a taste on the test bench. Before that, there was an obligatory power measurement on the program, which turned out to be quite sobering with 186 HP compared to the 199 HP measured at the beginning. The check, including reading out the fault memory at the specialist dealer, did not provide any new information.

After all, two re-measurements produced 193 hp. In any case, it wasn’t on the test stand, which tests exactly as ever. We have not yet found an explanation for the loss of performance, but we are sticking to it.

Mileage: 23,330, 9/2016

In the case of the Nippon super sports car, one topic has been a common thread running through the logbook from the very beginning: the moderately adjustable, jerky clutch with a short sliding path. Anyone who changes from another motorcycle likes to stall the engine. In the meantime, the third clutch linings are already doing their grueling job, the clutch basket was replaced when the odometer reading was 23,330.

Mileage: 13,650, 4/2016

Yamaha ordered a large number of the R1 models delivered in 2015 to the workshop to replace the gearbox. In the worst case, second gear wheels can break under heavy loads due to a manufacturing defect. This has already happened in individual cases.

The recall also affects the MOTORRAD endurance test machine, one of the first machines to be delivered in Germany, which was therefore recently in the Yamaha dealer’s workshop. An enormous amount of work because the engine has to be removed and partially dismantled.

Both gear shafts with all gears were swapped. The dealer needed two working days for this. We this occasion, the clutch linings were changed as a gesture of goodwill, since the clutch finally engaged hard and difficult to dose.

Since then, the machine has been running without problems, but not entirely without criticism. The clutching clutch is criticized, especially when the engine is cold, you have to be very sensitive when starting off.

Mileage: 7,800, 9/2015

The Yamaha YZF-R1 is only at the beginning of the MOTORCYCLE endurance test. It was clear that such a racer requires compromises in everyday life. For example the hard seat upholstery, the very dry set-up of the shock absorber, the diffuse clutch pressure point and the thirst when driving fast, which requires driving to the next gas station after 200 kilometers at the latest. But who should resent the heating iron??

However, the odometer of the Yamaha YZF-R1 is no longer ticking. This is due to a somewhat optimistic turning maneuver by a car driver, after which contact between the car and the motorcycle could not be prevented. The damaged parts are currently being replaced by the importer.
