RD400 / RD350 / RD250 / R5 Suspension


When your vintage Yamaha’s suspension system starts to wear out, a lack of comfort is the least of your concerns. Worn shocks and leaky fork seals affect the even handling that helped make the RD350 one of the most popular bikes ever for vintage Japanese café racer projects. Mikes XS has Monza Sport shock absorbers and brand-new RD350 fork seals to help restore your motorcycle’s handling.

That stiff rear suspension may not be a result of simple worn RD350 shocks, though. The swing arms on these fiery little 2-stroke street rockets must be greased regularly to help them deal with the abuse sport riders can dish out. Mikes XS stocks RD350 swing arm pivot shafts, needle shaft bearings, swing arm grease seal sets and swing arm bolt grease fittings to help fully restore your vintage Yamaha 2-stroke.
