German tuners Hoely have recently put their hands on a Kawasaki ER-6n and transformed it into a faster, better looking and implicit more challenging bike that they call ER6-RR.
The engine now develops an impressive 98bhp – incomparable to the approximately 75bhp of the standard bike–thanks to a series of upgrades from which the gas-flowed head with an increased compression ratio of 13.8:1, balanced pistons, rods and crank, high-lift cams, advanced ignition, a modified airbox and a full Akrapovic system are the most important.
Chassis components have been borrowed from Kawasaki’s top supersport models so the bike features ZX-6R’s USD suspensions and ZX-10R’s radial brakes. Yet, the frame hasn’t been stiffen up so let’s just hope they did the math well and this will manage with the around 23bhp extra.
As the picture shows, this Kawi is built to perform on the track and we reckon that the parallel-twin engine is now capable to be put against any standard four-cylinder middleweight sports bike out there. Now that’s a great achievement to take in consideration!
