How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a utilitarian, low-speed hauler, it excels at slow, steady cruising and carrying passengers or cargo rather than any form of spirited riding.
- Built for
- It has the charm of a rugged, old-world military-derived machine, full of mechanical character, vintage feel, and unhurried, deliberate presence on the road.
- Not ideal for
- This is not the machine for riders seeking speed, agility, cornering precision, or a modern, effortless riding experience.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
