Pattern Yamaha fork oil seal made by NOK. ID 35mm OD 48mm height 11mm. NOS, perfect condition. UK seller. Price is for one. Fits models shown above and the RD350LCYPVS, but does not have integral dust seal as does the genuine Yamaha seal. Would suit an application where there is already a separate dust seal. NOK is an original equipment manufacturer for Yamaha seals, but this one is a different design to OEM. Superseded by 1UA 23145 00.
