Rider Profile

Best For	Best suited to intermediate-to-advanced off-road riders who are comfortable with a tall, light, powerful open-class enduro machine.
Purpose	Built as a competition-focused enduro bike for trails, cross-country racing, and technical off-road terrain rather than road use.
Rider Fit	The tall 950mm seat height and minimal seat padding demand a taller rider with good fitness and standing-based riding technique.
Character	A raw, high-performance dirt machine that rewards aggressive, athletic riding with excellent agility and off-road capability.
Not Ideal For	Not suitable for riders wanting comfort, pillion capability, long-distance touring, or everyday street commuting.
