Vehicle Information
Yamaha TT-R125 Dirt Bike (2000-2026)
The Yamaha TT-R125, an enduring off-road motorcycle, has been a consistent presence in the market from its introduction in 2000 through the 2026 model year. Renowned for its reliability and beginner-friendly design, all models in this range are powered by a robust 124cc, air-cooled, SOHC, four-stroke, single-cylinder engine with two valves, paired with a 5-speed transmission. Fuel delivery is consistently handled by a Mikuni VM20 carburetor, ensuring a stable and accessible performance across all years. Throughout its production from 2000 to 2026, the TT-R125 has maintained a remarkably consistent core engine and chassis platform. There have been no significant mid-cycle generation changes that altered its fundamental architecture or performance. Instead, Yamaha introduced various trims to cater to different rider needs. The initial 2000 models included the standard TT-R125 and the TT-R125L (Large Wheel) with bigger wheels and a front disc brake. In 2003, the TT-R125E added an electric starter. The TT-R125LE, combining larger wheels, a front disc brake, and electric start, became a prominent offering, continuing through 2026. These were feature additions, not fundamental redesigns. FAQ:
