How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a muscular power-cruiser that delivers brutal straight-line acceleration and long-distance shaft-drive comfort rather than nimble cornering.
- Built for
- A big, boastful in-line triple cruiser that trades agility for sheer torque, presence, and effortless overtaking power.
- Not ideal for
- Not for riders seeking a lightweight, flickable bike for tight twisties or any kind of off-road use.
