High Quality Content by WIKIPEDIA articles! Yamaha produced road going 2-stroke motorcycle, based on the TZ250 Yamaha racing bike. Parallel twin, V-twin, and reverse cylinder variants. It evolved as a natural replacement for the popular RD 250/350 LC series of the 1980's It has Yamaha Power Valve System (YPVS) which raises and lowers the exhaust port depending on the rpm of the engine, the YPVS servo starts to open at about 6,000rpm. In standard form 50bhp is claimed at 10,000rpm. Although mid 40's is more realistic, and will not rev much above 9,500rpm in standard trim owing to the restrictive standard exhausts and ignition boxes. Production started in June 1986. At a cost of around $6,000 new on release it was seen as an expensive bike for a 250 cc, but given that places such as Japan and Australia had 250 licencing laws in place one can imagine the stir that something that could hassle 750's on a track caused. 2MA variant being the UK variant and the 1KT model being the domestic Japanese variant.
