Once you’re done collecting all the nuts and bolts for your classic RD350 or RD400 restoration, you still have a bit of work to do. Many of the fasteners on your vintage Yamaha require specific washers for their purpose. You’re not going to find these washers at your local hardware store, so look to Mikes XS for these difficult-to-locate, bike-specific washers. We carry OEM-equivalent brass cylinder head washers, Heiden filter/cooler mounting bolt copper washers, as well as 8mm chrome and 10mm stainless steel washers to help you complete your RD350 café project. We also stock RD250, RD350, RD400 and R5 exhaust head studs and chrome acorn nuts.
