Despite the bigger airbox the fuel tank has more capacity than stock, holding an extra three liters of fuel. The reshaped tank distributes the extra fuel carefully, with much of it being held low and to the middle of the bike so as not to upset the bike's low center of gravity. Power is nothing, they say, without control. Control is dictated by weight, generally, and for the most part, the less weight you have the better the performance of the bike. RS Performance has left no stone unturned in order to drive down the weight of the Evo 600.
Carbon fiber is everywhere, but most notably in the rear subframe.
Savory has completely removed the CBR's stock aluminum rear section and replaced it with a monocoque style rear section made entirely from carbon fiber that bolts to the lower frame by four bolts. A set of Brembo Goldline components grace the front wheel while four-pot calipers grip twin 320 mm disc rotors. All of this is held together by a pair of inverted 43 mm Ohlins forks, complete with titanium-nitrade sliders similar to those found on the new Ducati Superbikes. An Ohlins mono-shock helps keep the back wheel under control. The front and rear suspension set-ups are both fully adjustable.
