The '''Yamaha JT-1''' was a 60cc 2-stroke, [[off-road]] model produced by [[Yamaha]] beginning in 1971. It was more commonly known as the '''Mini Enduro'''. It was the first small-sized two wheeler that looked like larger [[motorcycles]]. Dad could ride his [[Yamaha DT-1|DT-1]] and Junior could look just like him on his Mini Enduro. | {{Motorcycle | ||

The '''Yamaha JT-1''' was a 60cc 2-stroke, [[off-road]] model produced by [[Yamaha]] beginning in 1971. It was more commonly known as the '''Mini Enduro'''. It was the first small-sized two wheeler that looked like larger [[motorcycles]]. Dad could ride his [[Yamaha DT-1|DT-1]] and Junior could look just like him on his Mini Enduro. This model was superseded by the [[Yamaha JT-2]]. | |||
The 1971 JT1MX was a mild 60cc rotary valve little beastie with a four speed box, autolube, primary start, and approved USFS spark arrestor. To keep costs down, Yamaha cut corners on the suspension, and designed the front forks with one spring in the right fork leg, using compression damping, with no spring on the left side, with rebound damping. The rear shocks used rebound damping, which was just fine for a beginner. | |||
