Segment: Trial
Production years: 2002, 2003
The TT-R90 is the smallest member of the Yamaha 4-stroke family, sporting an air-cooled 89cc engine with smooth, predictable and non-intimidating power delivery. The bike retains the automatic clutch and the 3-speed transmission of the PW80 machine, since it looks like the young riders really enjoy the automatic clutch.
Built like a tank, just like other similar Yamaha machines, the 2002 TT-R90 can effortlessly cope with the beating kids put such bikes through.
