Dirt Rocket Pro Spec combines the reliable, effortless,quiet and instant acceleration of an electric motor with the ‘off road’ appeal of a powerful motocross bike–capable of faster speeds. Therefore, the Dirt Rocket Pro Spec is exclusively for use by mature riders. This product shouldn’t be ridden on public streets but only in off-road conditions.Its features have been selected to not just be functional, but to offer the best combination of performance, value and fun! A 48V lithium-ion battery pack is good for 120minutes of run time while the powerful 1600W high-torque motor propels riders at speeds up to28mph (45km/h).The dual speed high output controller provides options for Sport mode, for full power and speed, or Normal mode, which reduces the top speed to extend battery life.More notable specifications include the motorcycle standard wheels, 14”in front and 12”in rear, mounted with knobby tires. The link-tuned suspension provides supple small bump compliance as well as big hit, bottom out resistance with 120 mm of travel, and there are four possible shock positions to fine tune the suspension characteristics to suit riding style. Dual disc brakes and hydraulic coil sprung front forks round out the damping and control features.
