c.1966 Yamaha 305Cc YM1 Registration no. NTL 116F Frame no. Y26-29686 Engine no. M1-29686 Following in Honda's footsteps, Yamaha entered the '350' class with an enlarged version of an existing 250cc model, launching the YM1 in 1965. Actually 305cc, the YM1 was based on the YDS3 of 1964, which was a new design in almost every respect and notable as the first Yamaha twin to feature 'Autolube' automatic lubrication by means of a gearbox-driven pump. For the YM1 the YDS3 engine was both bored and stroked, producing 26bhp, a two horsepower improvement over the '250'. Apart from the top end, the two motors were identical. Stylish and fast, the enormously successful Y-Series continued Yamaha's reputation for offering more performance per £ than any of its rivals. The model was built until the end of 1968, latterly as the mechanically improved but cosmetically almost identical YM2. Imported by 1998 and subsequently restored, this rare Japanese classic was first registered in the UK on 2nd June 2009. Eight years later it was sold by Bonhams at our Spring Stafford Sale in April 2017 (Lot 282). At that time we were advised that the Yamaha had been dry stored for a few years (the tax disc expired in August 2011). We had also been advised that the machine was built for the 1966 model year and first registered in the USA in 1968. A model rarely encountered in the UK, this YM1 was purchased by the current private vendor in February 2023, since when it has been dry stored and turned over/used sparingly. The machine is offered with MoT to 19th January 2027; a V5C Registration Certificate (where it is registered for Historic tax exemption); and an invoice for service work carried out by Dave Woods Racing where a new clutch was fitted.
