1989 Yamaha RD350F2 YPVS Registration no. F758 SHU Frame no. 1WT016891 Engine no. 1WT016891 After only a couple of years in production, the original RD350LC was superseded in 1982 by the RD350 LCII, a model better known by the initials 'YPVS' standing for 'Yamaha Power Valve System'. Developed on the firm's Grand Prix bikes, the electrically operated power valve varied the effective exhaust port height according to engine revs, enabling Yamaha to tune the engine for increased top-end power while maintaining mid-range tractability. Yamaha slotted this heavily revised engine into a new frame equipped with linkage-operated mono-shock rear suspension, while the old rear drum brake was replaced by a disc. After little more than a year the LCII was dropped, being replaced by the faired RD350F and naked RD350N models. Production continued in Japan until 1988 and then in 1992 was revived in Brazil. According to the vendor, it is highly original with no modifications, and retains its tool roll and tools, and the original owner's manual. Although the V5C states six former keepers, the Yamaha was in the same family ownership from new until our vendor purchased it in 2022. (The first recorded owner was the supplying dealer, Fowlers Motorcycles, whose name is on the numberplate.) The bike has only 12,800 miles on the odometer and is offered with sundry bills, a V5C document, and MoT to March 2024.
