2013 KAWASAKI ZX-10R FROM-£7,300
The chromoly crankshaft (it used to be cast steel) was located 10º and 28mm higher,g, and the transmission shaft located above the other two (107mm higher) to centralise mass, over the previous bike. The cylinder bores’ centres are set 2mm towards the exhaust side, reducing lateral piston force, and use lighter pistons with shorter skirts and thinner rings. Intake valves are 1mm bigger, at 31mm, and intake tappets were larger, too. Even the brand new 2017 ZX’s engine only makes a bit more power than this. The seven-piece, all-cast aluminium frame follows a more direct line to the swingarm pivot point. The seat has been lowered by 17mm. The swingarm is a three-piece, all-cast unit, made longer to improve drive. The CoG is 4mm lower than previously, while the rake is cut by half a degree and trail shorted by 3mm to 107mm. Showa’s 43mm Big Piston Fork sits up front sporting their effective but initially peculiar feel, with a horizontal monoshock at the back. There is an ABS equipped version available.
