How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A Soviet-era sport-styled single intended for spirited backroad riding rather than serious touring or off-road use, despite its dual-purpose-style tyre sizing.
- Built for
- Buzzy, characterful, and old-school, this bike rewards mechanical sympathy and a tolerance for basic drum brakes and dated two-stroke quirks.
- Not ideal for
- Not a good fit for riders wanting modern performance, long-distance comfort, or serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
