The '''Yamaha IT425''' was an [[enduro]] [[motorcycle]] produced by [[Yamaha]] only in 1980. | |||
This bike was only produced for 1980. The engine for this machine was the ill fated 1979 [[Yamaha_YZ400|YZ400]]. The bore was increased from 82mm to 85mm (the common size for previous YZ400s) which gave this engine more life than the YZ400 that it was spawned from. | This bike was only produced for 1980.
