How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for relaxed boulevard cruising and weekend rides where laid-back style and V-twin character matter more than outright performance.
- Built for
- A classic custom-cruiser feel with a punchy DOHC V-twin, belt final drive smoothness, and enough midrange torque to feel muscular without being intimidating.
- Not ideal for
- Not the right choice for riders wanting sharp cornering agility, off-road capability, or serious high-speed sport performance.
