How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's a lightweight two-stroke twin from the early 1980s built for simple commuting and leisurely cruising rather than speed or long-distance touring.
- Built for
- It has the charming, buzzy character of an old-school two-stroke twin, with a narrow power band, distinct exhaust note, and the mechanical honesty of drum brakes and a 4-speed gearbox.
- Not ideal for
- It's not for riders wanting modern acceleration, sustained highway speeds, off-road capability, or confident stopping power in emergency braking situations.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
