Title: TY250B bore x stroke
Post by: JC on November 19, 2008, 04:26:15 pm

Can anyone tell me what the borexstroke is on the early TY250s?

I always tho't it was the usual 70x64mm, but was reading a DirtBike test last night which claimed it was 70.7x65.9mm. Seems wrong to me but I'm not that familiar w TYs.

From memory it is 70mm and goes up in .5mm oversizes
