Yamaha RD350 YPVS & RZ350 Close Ratio Gearboxes
A full close ratio gearset for the RD350 and RZ350 with racing undercut dogs for fast, accurate gear changes and positive retention. With ratios optimized for racing, this gearbox will make for a large improvement in acceleration and top speed on the track.
We also offer a second set of ratios which are a little wider than the race set and will suit road bikes and street specials.
A new kickstart idler gear is included in the assembly and runs on a needle bearing to prevent the common wear issue of the standard part.
We supply the fully assembled input and output shafts ready to fit. All gears are Superfinished as standard.
