How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a big-bore dual-sport adventure machine, it excels at long gravel and trail routes with the ability to cover real distance thanks to its large fuel tank.

- A gruff, characterful big single that rewards a relaxed, standing-up riding style with strong low-end torque and a rugged, go-anywhere feel.
- Not ideal for
- Not a good match for shorter riders, pure pavement commuters seeking smoothness, or anyone wanting sport-bike acceleration and top-end speed.
