This new manual from Haynes groups together three of Yamaha's A1 learner category models, all sharing a common engine unit. The ultra cool MT and race styled YZF share many components beneath their bodywork. The WR-R and its WR-X Supermoto stablemate have only engine and fuelling in common with the MT and YZF.
All aspects of servicing and repair are fully covered and accompanied by hundreds of photographs taken during the stripdown and rebuilt procedure. Complex systems, such as fuel injection and ABS are demystified and the manual contains colour wiring diagrams.
