Vehicle Information
Yamaha HT1MX Dirt Bike (1971)
The 1971 Yamaha HT1MX is a legendary 89cc two-stroke motocross motorcycle, purpose-built for competition. As a specialized trim within the HT1 series, it offered significantly enhanced performance compared to its enduro counterpart, the HT1B, establishing itself as a formidable machine on the track. While there wasn't a mid-year generation change in 1971, the HT1MX represented a major evolution from the 1970 HT1 and the 1971 HT1B enduro models. The HT1MX boasted a more powerful 89cc engine, delivering 14 BHP at 9,500 RPM with an 8.1:1 compression ratio, a substantial increase over the 8.5 BHP of the HT1B. This performance boost was achieved through specific porting, a unique carburetor (VM24SH), and a competition-oriented exhaust. Designed purely for motocross, it featured a high alloy front fender, lacked lights, and was distinctively finished in Competition Yellow, setting it apart as a dedicated racing machine. Q: How do I ensure I'm selecting parts for the correct 1971 HT1MX model?
