This had been Yamaha's opportunity to stun the world with an outright fire-breathing race-bike for the street, reflecting their successes on the racetrack, but instead it seemed more like a steady tourer. Actually, it was in many ways a two-stroke equivalent of the CB450, so perhaps that was a deliberate choice. The chassis was essentially a larger version of the YDS5 frame with the more powerful brakes, thanks to new drum linings. Suspension was quite firm, and steering neutral. The YR1 was a decent bike, but it could have been so much more. | This had been Yamaha's opportunity to stun the world with an outright fire-breathing race-bike for the street, reflecting their successes on the racetrack, but instead it seemed more like a steady tourer.
