The revival of the S 1000 RR. Finally, one might say. Although BMW’s super sports car had, from its inception, provided stratospheric performance, it was beginning to suffer from a dated design and technique that needed updating. Because the competition did not deprive itself of tipping into the overbidding to undermine it. If it evolved almost wisely, here it changes dramatically in 2019. Chassis, electronics, mechanics, ballistics: everything is reviewed. Sometimes a lot, often everywhere. Before discovering all its mods, let’s announce its business card. And it will hurt: the fourth generation S 1000 RR is 207 horsepower for 197 kilos.
A missile … or maybe a little more. A tactical interceptor !
It has been 10 years since this hypersport, the first from the Munich manufacturer, arrived on the market. By shaking everything in its path. And since that time, its unique design has only evolved through retouching. The profound internal evolutions are now finding a stylistic overhaul to suit them. It really is a new S 1000 RR, with an updated look from muzzle to tip.
Let us dwell on this minimal upheaval and yet … The asymmetry familiar to the machine, and recurrent on a lot of Bavarian models, is no longer appropriate. We do like everyone else. No more round headlight on one side and polygonal on the other, no more differentiated sides.
What a change in personality. The fork crown kept only the contours of its air intake. The look is minimalist, menacing, stuck in the edges of a new BMW identity. The forms become more complicated, seek to mark, project the sportswoman in her new genetics. Pay attention to the creepage line running from the top of the rear tubular frame, crossing the junction between the fairings, then cutting through the base of the front fender. It seems much more compact, while it is 23mm taller. Affirming an undeniable break with (all) the previous vintages, the RR gives us a slight impression of … Japanese sports car. Everyone to see, but we would have preferred it to be influenced by the Italian school.
Before seeing what the boiler has in the stomach, let’s take a look at a little trick. Really squeezed out the asymmetry? Look carefully at the height of the cylinder head. There are still, in a reduced model, the gills of a shark on one side; and not on the other. The S 1000 RR still maintains an inheritance relationship..
Volcano fever in the cylinders! From its birth, this bike was noticed by its engine, overpowered, extravagant, with always stories to tell between each curve. It goes into the Hulk phase, with overhaul and variable distribution. Enough to give it new vigor.
The ShiftCam process, inaugurated very recently with the R 1250 series (GS, GSA, R, RT, and RS), is also making its debut in the 999 cm3 in-line 4-cylinder. The shaft on the intake side contains two sets of cams, making it possible to take advantage of a profile adapted to usual speeds and another favoring power at high speeds. At 9,000 rpm, two electromechanical actuators operate on the splines in order to switch the ACT from the partial load profile to that of full load. Thus, at low and mid-range, the engine is better filled, offering a level of torque similar to that of the S 1000 R roadster..
Once pushed to its limits, the boiler will express with rage its increase in power. 8 horses gained, allowing a formidable 207 hp at the same speed as before, or 13,500 rpm. What might scare the hell out is that the docks have rarely found the 199 ex-RR nags before … it was often more. We can thus hope, even fear, a monstrous power for this new chapter..
The maximum torque does not change, still 11.5 mkg at 11,000 rpm. It is its presence that evolves, offering more than 100 Nm (10.2 mkg) from 5,500 to 14,500 rpm. Let’s stay a moment in the figures to specify that the maximum speed gains 400 revolutions, peaking at 14,600 rev / min. BMW upgrades it to the Euro5 standard in 2021 without losing power.
The ShiftCam technology also allows a fuel reduction of 4% as well as a reduction in pollutant emissions. But it’s not just variable admission as an internal change. To save weight, the titanium valves are hollow; ACTs are also hollowed out.
Engine manufacturers have managed to save a lot of weight on the engine. Although the ShiftCam comes with a kilo to add, the block has however managed to lose 4 kilos. Everything that could be optimized was optimized: idle gear between the ACTs and the free crankshaft, combined water and oil pumps, reduction and optimization of the majority of the gear elements. As a bonus, the block has been reduced by 12 mm in width. The precision of the gearbox has been improved, as has the air intake, always with the presence of variable-length cones..
How could we gain weight again? With the exhaust. The silencer is much more compact, almost of an R1 size, preceded by catalysts and a huge plenum chamber – despite this, 1.3 kilos managed to fly away.
A little mass grappled on the frame, the rear suspension sketch, 1.6 kg with the new rims, to result in a net loss of 11 kg. Staggering! The S 1000 RR is stuck on a 197 kgs, pile hair between a Ducati 1100 Panigale V4 and a Honda CBR 1000 RR. At a glance, the optional M package saves another 3.5 kg, in particular thanks to the carbon wheels.
This significant weight loss should help to remedy, in part, one of the rare shortcomings of the S 1000 RR. Impressive watts, the sport marked time in agility compared to the competition. The drastic regime will have its effect, and the new chassis much more.
The spine renews its confidence in an aluminum perimeter frame, except that this one relies much more than before on the engine for its rigidity. With an extended load-bearing function, the thruster plays an even more tactical role and allows the radically modified frame to gain 1.3 kgs. The width between the legs decreases, from 13 to 30 mm depending on the location.
Weight saving also dictated the design of a new rear frame, which consists of a tubular trellis.
The “Flex Frame” didn’t say it all. The intensive search for traction and efficiency results in a completely new swingarm. No more banana element, place for an arm with reinforcement under the main spars. 300 grams lighter than the old one, it now offers the possibility of modifying the height of its anchor point from +2 to – 2 mm. Trackers with extensive experience will appreciate it. Fans of beautiful parts will be seduced by its finish, enhanced with small plates with the name of the machine on one side and technical information on the other (arrow – tire pressure).
Suspensions, do we touch it or not? Of course, since BM has decided to change everything. As such, the rear shock absorber is anchored perfectly vertical, and further away from the engine to prevent its heat from disturbing the hydraulic work. Optimized with a lot of internal modifications, it is as usual adjustable from anywhere.
A new inverted fork of smaller diameter (45 mm against 46 previously) takes place. It weighs 300 grams less and also offers compression, rebound and preload settings. The front grows in importance as more weight is leaning on it – the weight distribution has increased from 52.3% to 53.8%.
The suspensions can optionally receive the new generation DDC controlled damping. In 10 milliseconds, it adapts the damping it deems most relevant, following the laws of the “Road”, “Rain”, “Dynamic” or “Race” modes; see the “Race Pro” Modes.
What are “Race Pro” Modes? An option giving access to a series of additional Modes, “Race Pro 1 to 3”, totally circuit oriented. As well as engine brake adjustment and Hill Start Control Pro – same function as the start-up assistant in standard height, supplied as standard, but self-activating as soon as the slope is greater than +/- 5%.
Without pushing the on-board electronics to the level of an HP4 Race, the S 1000 RR is well endowed with piloting aids with a 6-axis inertial unit fine-tuning the efficiency of traction control, anti-wheeling and ABS Pro, active in curves. Plus the Up & Down shifter, the standing start aid and the speed limiter in the pits. The cruise control preferred to stay within the range of options.
The S 1000 RR was one of the last sports cars to inform the pilot via a needle tachometer and liquid crystal window. It is updated with a 6.5-inch TFT screen, which can display 4 different themes and information galore. The classics of course, with speed, bar graph or analog engine speed, trips, fuel gauge and gear engaged. But also the lap times, the angle of inclination, the level of deceleration, the electronic assistance settings, an overspeed indicator, the use of the throttle … to configure its display with great care.
Its lighting is entrusted from end to end to LEDs, with a visual supposed to offer the appearance of a racing car. The indicators are no longer on the sides and have migrated into the mirrors. Seems we see them better like this.
Let’s not forget the braking. Still performed by 320mm discs at the front, but the calipers have changed. More from Brembo M4; the new clamps are branded BMW, with 4 pistons and radial mounting. For the rear, a 220 mm disc alongside a single-piston caliper.
Almost a regret; given the transformation of the S 1000 RR, a good pair of Brembo Stylema would have superbly completed the endowment.
A rouste! This is what the BMW S 1000 RR intends to inflict on the category. Its well-known recipe is, however, always more impressive: less weight and more watts. Its arguments are more than convincing, its design propels it towards a new future, and its desire to slaughter the stopwatch is even more vivid. Will this chapter be the one that will unlock the greatest rewards for him in the world championships? Now turn the accelerator and hold on; you will have to cash in what she will send you in the buffet.
************** Update of June 22, 2019:
In mid-June 2019, BMW suspended sales of its Bavarian missile due to a machining problem in the gearbox. 110 machines sold in Germany have been recalled for an engine change. Regarding the French market, absolute silence. No official information has been communicated but what is certain is that in France also the sales of the Bavarian hypersportive have been suspended..
