PurposeBuilt for rally raids, long off-road adventures, and technical enduro terrain rather than pavement performance.
Rider FitThe tall 955mm seat height and 138.5kg dry weight demand good rider fitness, leg length, and off-road bike-handling skill.
CharacterA high-strung, race-derived 450cc single with a big 30-litre tank, premium KYB suspension, and rally-inspired ergonomics for navigation-style riding.
Not Ideal ForNot a good fit for short riders, city commuters, or anyone wanting a plush, low, easy-going road bike.
