Rider Profile

Best ForThis bike suits intermediate to experienced off-road riders comfortable with a tall, powerful open-class enduro machine.
PurposeBuilt as a dedicated closed-course and trail enduro weapon, excelling at technical off-road terrain, motocross-adjacent trails, and cross-country racing.
Rider FitThe tall 37.9-inch seat height, 275 lb wet weight, and firm long-travel suspension demand good rider fitness, leg length, and off-road bike-handling strength.
CharacterLight, nimble, and torquey, it rewards aggressive, standing-up riding with sharp cornering response and confidence over rough, unpredictable terrain.
Not Ideal ForIt is a poor choice for daily commuting, highway touring, carrying a passenger, or riders seeking plush comfort and low seat height.
