The last 350cc aircooled production roadracer [[Yamaha]] ever produced, the R5 roadbike based TR3 was released in 1972. Changes to the bike including bore and stroke configuration, the engine now sported the 54mm stroke that was to be the mainstay of the TZ range for the next 8 years, a rise in compression ratio, well as a new crank and a 6 speed gearbox replacing the old 5 speed, though as for the TD3, provision to "block out" sixth gear was there. Like it's "little brother" it didn't live entirely up to expectations either, also suffering from detonation and seizures at regular intervals**. Peak horsepower rose by 2 to 58bhp. | The last 350cc aircooled production roadracer [[Yamaha]] ever produced, the R5 roadbike based TR3 was released in 1972.
