How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built for short, stylish rides around town and leisurely backroad cruising rather than any kind of performance or long-distance riding, with the Wrenchmonkees custom treatment emphasizing look and character over practicality.
- Built for
- This is a soulful, air-cooled retro single with a distinctive titanium megaphone exhaust note and hand-built soft panniers, prioritizing analog charm, simplicity, and visual style over outright capability.
- Not ideal for
- This is not the bike for riders seeking high speed, long-haul touring comfort, two-up riding, or any off-road ambition given its street tires, single disc brake, and drum rear brake setup.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
