The traditional British method of building a 350 - to sleeve down a 500 - usually resulted in an overweight sluggard with little more performance than a 250. The customary Japanese approach - over-boring a 250 - achieved exactly the opposite: a machine as light as its quarter-litre sibling yet with sufficient performance to see off most 500s. Yamaha's exciting YR5 is a case in point: an over-bored YDS7, it weighed a little over 300lbs, produced 36bhp from its piston-ported two-stroke engine, and was good for around 100mph. The cycle parts bore close resemblance to those of the TD2 and TR3 racers, so good handling was assured. Introduced in 1970, the YR5 was superseded by the reed-valve induction RD350 in 1973.
This beautiful YR5 was purchased this year from a collector (its third owner) having been restored in 2012. Serviced approximately 3,000 kilometres ago (the current odometer reading is 42,920 kilometres - approximately 26,700 miles), it is described by the vendor as running and in generally very good condition. The machine is offered with Netherlands registration papers and comes with keys. It should be noted that the engine is of earlier manufacture than the frame.
