Technical Overview
2001 GAS GAS TXT 321 Technical Analysis & Specification Breakdown
Positioned in GAS GAS's trial motorcycle lineup, the 2001 GAS GAS TXT 321 features a 328 cc (20 cu in) single cylinder, two-stroke configuration. In factory specification, peak output is rated at 17 HP (12.4 kW) at 5,200 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 51.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the TXT 321 measures 76 kg (168 lbs) dry, translating to a power-to-weight ratio of 0.22 HP/kg (4.47 kg per horsepower). Rider ergonomics and chassis geometry center around a 705 mm (27.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 3.2-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
