Power & Oil-Cooled Performance

• 137.2cc (140cc-Class) Oil-Cooled Engine: SOHC four-stroke powerplant generating 8.0 kW (10.7 hp) @ 7,500 rpm and 11 N·m of torque @ 5,500 rpm. Dedicated oil cooling dissipates thermal stress under aggressive riding.
• Manual 4-Speed Transmission (N-1-2-3-4): Crisp manual clutch actuation and positive foot shifts deliver exact power modulation through turns, berms, and straightaways.
• Dual Starting Reliability: Equipped with electric push-button start and heavy-duty kick start backup.
• Proven Chassis: Built on the rigid, lightweight frame shared across the premium TT family, reinforced with a heavy-duty underbody skid plate.

Suspension, Brakes & Handling

• Long-Travel Inverted Front Forks: 31.5 in (800 mm) inverted forks enhance front-end stability and bump compliance over rocks and rough trail sections.
• Rugged Rear Monoshock: 14.2 in (360 mm) rear suspension delivers smooth, controlled rebound over jumps and whoops.
• Calibrated Hydraulic Disc Brakes: Front and rear wave-rotor hydraulic disc brakes ensure sharp, fade-free deceleration.
• Big Wheel Setup: Standard with 17-inch front and 14-inch rear knobby wheels (optional 19"/16" available) to roll over roots and deep ruts.
