The tank spoilers and rear side panels are slightly wider than the seat for optimized control when standing on the pegs, while the shape of the fuel tank is optimized to offer freedom of movement when tackling tricky technical terrain. A robust engine guard also makes its intentions known by protecting the engine and exhaust when venturing off the tarmac into the dirt.
