How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for riders who want big-bore muscle-bike thrills with a retro Kawasaki styling twist, equally happy blasting backroads or cruising boulevards.
- Built for
- It has a big-hearted, muscular in-line four character with strong midrange torque, a firm chassis, and old-school street-fighter attitude rather than razor-sharp modern agility.
- Not ideal for
- It's not a good fit for brand-new riders, or anyone wanting a lightweight commuter or a genuine off-road capable machine.
