Rider Profile

Best ForWell suited to beginner and intermediate riders thanks to its light weight, tall but manageable seat height, and mellow single-cylinder power delivery.
PurposeBuilt primarily as a dual-sport/enduro machine for trail riding and light off-road exploration, with occasional street use.
Rider FitThe tall 890mm seat height and 138kg dry-ish weight favor taller riders, but its slim frame and low mass make it easy to manhandle at low speed or off-road.
CharacterA nimble, low-stress trail bike that rewards playful, momentum-based riding rather than outright speed.
Not Ideal ForNot a good fit for riders wanting sustained highway touring, high top speed, or a plush two-up passenger experience.
