LKM-Suzuki Hayabusa test

Force of nature with extras

Should it be over 200 hp? And the 300 km / h wall shouldn’t be a hurdle? Well. The Rhinelander Hennes Lohr unleashes the storm that slumbers in the Hayabusa with a lot of precision work.

Everything seems normal. With a satisfied purr, the Hayabusa pulls along in the left lane of the motorway. The wind shakes the helmet a little, tugs cheekily at the shoulders, and when a short, free piece shows up or an obtrusive horsepower droschker is about to disappear from the rearview mirror, the Suzuki pulls one out of its sleeve as energetically as it is loosely when turning the whisk shaken intermediate sprint.

Just something is different. This scenario does not take place near the recommended speed. Not even close. It happens at 220 km / h. And the vehemence with which the Hayabusa pulls the tachometer needle up the scale simply takes your breath away in these speed regions. The fact that the driver remains quite undisturbed by the approaching wind is thanks to the higher MRA disc. The brilliant acceleration experience, on the other hand, that of Hennes Lohr, head of LKM in Wachtberg-Villip near Bonn. He elicits a proud 215 hp from the Hayabusa. Without turbo, displacement expansion or other special parts antics. Simply through classic tuning. The cylinder head received expanded ducts that were optimized on the flow bank, valve seats turned outwards to match, revised combustion chambers and adjusted gap dimensions.

The exact gauging of the combustion chambers and equalization of the compression is followed by the careful readjustment of the control times by removing the camshaft gears from the shafts and pressing them back on with meticulous measurements. Finally, Lohr optimized the ignition and the injection map. And so that the fun of the excessive power lasts from first to last gear, the Hayabusa can also turn in the upper speed levels up to the limiter. She actually does. And how. Not explosive, with a bitter kick. But with monumental force. From the bottom. As unyielding as a huge tidal wave that makes it clear that nothing can stop it and that it carries everything away.

Performance

Jahn

The slightly martial outfit of the LKM-Hayabusa matches the impressive performance.

In this way she paves every curvature that presents itself on the country road with long, black stripes in the most varied of shades. And on the autobahn, it slams through the 300 km / h wall after just 17.3 seconds, only to fidget at the limit shortly afterwards. According to GPS, this is 304 km / h due to the two teeth shorter gear ratio on the chainring. With the longer original translation, more would easily be possible, because while the series performance drops from 9500 rpm, the LKM tier increases in power until it is locked. Fortunately, the engine’s manners did not suffer during the performance cure. Except for a faint tingling sensation of 7000 rpm, the unit runs as smooth as silk, driving through town in sixth gear is a snap, and the throttle response works perfectly. In this way, the enormous pressure can always be called up in a well-portioned and nerve-friendly way.

Now, for the sake of correctness, it must be said that the 215 hp are measured without a dB eater in the hexagonal end pot. With a TÜV-compliant plug, it should be about six to eight less. On the one hand, this is easy to get over in view of the exemplary performance curve and impeccable manners, and on the other hand, the background noise is also quite subtle. According to Lohr, the LKM-Busa manages to comply with the exhaust gas values ​​without any problems, and "the increase in performance through this optimization is within the legally permissible range of 20 percent".

Frame and brakes

So that the strengthened Hayabusa doesn’t drive the beads of sweat onto the forehead of her driver while exhausting her potential, the chassis and brakes also received a little attention. ABM Peak brake discs give the pale series brakes a little more bite, without, however, becoming a real two-finger stopper in terms of braking performance and controllability. You can certainly do more with other coverings. In addition, the brake discs began to rub a little towards the end of the test. The Rhinelander put the chassis in the hands of Benny Wilbers. Instead of the standard linearly wound springs with 9.75 N / mm, he gave the fork a linear spring rate of 10.5 N / mm, swapped the oil for one with a slightly lower viscosity and increased the air cushion from 100 to 110 millimeters. Wilbers replaced the shock absorber completely.

In terms of coordination, it is, like the original part, no softie, but allows significantly more comfort without sacrificing stability. It is also six millimeters longer, which means that the rear end is around ten millimeters higher and handling is faster. The fact that the LKM-Hayabusa has noticeably increased in handiness can also be attributed to the Galespeed forged alu wheels and the Akrapovic exhaust system, which alone is responsible for the majority of the 19 kilogram weight reduction. The appealing fork perfectly ironed the omissions of the road construction authorities. Tea falcon plows absolutely stable even through high-speed motorway curves studded with heels. Only when the maximum speed is maxed does movement arise, and it is advisable to use the compression level reserves of the fork, which is still comfortably tuned. In any case, this does not reduce the comfort. Anyone who wants to chase the Hayabusa over narrow, angled slopes is advised to do so anyway.

However, she quickly makes it clear that despite the significant gain in handiness with her still stately 245 kilograms and the tendency to take a slightly wider curve at the end of a curve, she is ultimately not a super athlete, but does not want to be misunderstood. Because in this form it is more than ever an impressive, very confident base for quickly and at the same time relaxed bridging of long distances, which delivers that extra kick when required.
