How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for laid-back boulevard cruising and easy highway travel with strong low-rpm torque rather than outright top-end speed.
- Built for
- A classic-styled, chrome-laden parallel-twin cruiser that prioritizes smooth, relaxed torque delivery and comfortable long-haul stance over sharp handling.
- Not ideal for
- Not the right choice for riders seeking aggressive cornering performance, off-road capability, or lightweight flickable agility.
