K5-K8 Suzuki GSXR1000 Full Race Gearbox
Comprises input shaft and all loose gears. Assembles using standard output shaft and all bushes, spacers, circlips and bearings from the Suzuki gearbox.
Clutch nut is a full thread type and retains the standard lock spring washer and is supplied with the gear set.
The two different ratio’s are our own specification and we feel will give a significant benefit over the road bike ratio’s in race use.
To improve gear changing, all gears use only three dogs with sufficient “backlash” to give fast gear changes without the need to compromise as in the standard four dog gears. All dogs are undercut both in drive and overrun, unlike the road box which is only undercut on the drive faces and not at all on first gear.
