This machine has had repeated success at the Junior Isle of Man TT, making it one of the most sought after machines in its class. Standard features include a telescopic front fork, dual shocks as a rear suspension, a dual seat, a large, 23-liter (6-gallon) fuel tank, a small windscreen, a blacked-out frame and laced wheels.
