2011-2012 Kawasaki ZX10R Taller 1st & 2nd Gear For Standard Gearbox

<< back to products

We have designed a taller 1st and 2nd gear more suitable for circuit racing than the standard ratios.  We supply a new input shaft and 1st & 2nd output gears which need to be built into the standard gearbox.  This is a cost effective upgrade for improving the standard Kawasaki gearbox for use on the track.

 

NOTE: The gearbox should be assembled using all other genuine Kawasaki gears, bearings, bushes, thrust washers etc.

 

Please contact us if you want other ratios for the standard gearbox, or a full close ratio gearbox manufacturing with racing engagement dogs.

 

Available With Superfinish
