How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built specifically for technical trials riding and obstacle navigation rather than speed, distance, or road use.
- Built for
- A pure, minimalist trials tool that thrives on razor-sharp low-speed agility, tractable low-end power delivery, and total rider control over the bike's balance.
- Not ideal for
- Not for riders wanting highway speed, passenger carrying, long-distance comfort, or any kind of touring capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
