Suzuki RF900Rseries

The 900 cc model is fitted with a 5-speed constant mesh box (using the exact parts from its elder GSXR1100 brother), while the 400 and 600 use 6-speed versions to make the most of the smaller displacement power units.
The lubrication of the gearbox and clutch is shared with the crank and engine lubrication. The 900 uses a RK532GSV2 x 110 links chain, although can be converted to use more readily available specifications. The 600 uses a RK50MF0Z1 x 108 links chain. The usual 1-N-2-3-4-5(-6) gearbox shifting pattern is observed. The 900 uses a hydraulically actuated clutch, while the 600 and 400 use cable actuation.
