With a few modifications, the Pit Bull/KWS Motorsports BMW S1000RR was able to hit a top speed of almost 328km/h. It now holds the world record for being the fastest production superbike ever...!
The BMW S1000RR is the current no.1 favourite superbike for most motorcycle speed junkies, and for good reason – it really is fast. Very, very fast. The bike now holds the ECTA top speed world record for 1,000cc production motorcycles, with Chad Millholland hitting 325.192km/h on a stock S1000RR. With the bike mildly modified, which made it eligible for the modified production bike top speed record, Chad then went on to do 327.701km/h on the same S1000RR. In both cases, the BMW hit those speeds from a standing start, over a 1.6km long straight at an abandoned airfield near Maxton, North Carolina. The bike had been fettled by two specialist companies – Pit Bull and KWS Motorsports.
For the production bike top speed record, the S1000RR was required to keep its stock bodywork and exhaust system, but did get new set of camshafts, spring and retainer system, lightweight pistons and con-rods. In addition, the bike was also fitted with a new steering damper kit and revised gear ratios. For the modified production bike top speed run, the S1000RR was then also fitted with a LeoVince exhaust system, double bubble screen and a more aerodynamic front fender.
‘The Pit Bull/KWS Motorsports BMW S1000RR is an impressive package for sure. It takes a lot of horsepower to get a stock bike above 320km/h and this S1000RR just takes off like a rocket from 12,000rpm to redline. The internal ratios are perfect and the OEM quick-shifter is best shifter I have ever used. The whole package is great and the bike was set up perfectly,’ says Chad.
And even though the S1000RR is already the fastest production bike on the planet, BMW are not exactly sitting around twiddling their thumbs. The company is already working on fine-tuning and optimising the bike’s ergonomics and windshield, to make sure the machine is even faster for the 2011 World Superbikes championship. BMW riders Troy Corser and Leon Haslam have been spending time in a wind tunnel in Munich, Germany, in order to find out what riding position and windshield combo works best for minimising drag and maximising top speed.
‘The riding position is a main factor for the aerodynamic efficiency of the overall package of rider and bike,’ said Rainer Bäumel, Technical Director Team BMW Motorrad Motorsport. ‘The intensive work in the wind tunnel enabled Troy and Leon to find out what riding position is the best for them personally. At the same time, we tried to improve the aerodynamic efficiency of the bike as much as possible within the strict technical regulations. This is why we evaluated several different shapes and positions of the windshield,’ he added.
The Aprilia RSV4 Factory APRC SE and 2011 Kawasaki Ninja ZX-10R notwithstanding, the BMW S1000RR looks all set to continue its dominance on the street as the fastest, most powerful production superbike ever. And in 2011, it just might extend that dominance on the racetrack as well…
