How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a hardcore offroad and enduro weapon, it excels at trails, technical terrain, and competition-style riding rather than commuting or highway use.
- Built for
- It rewards an adventurous, dirt-focused rider who enjoys precision handling, standing attack riding, and minimal creature comforts.
- Not ideal for
- This is not the right bike for riders wanting a comfortable commuter, a passenger-friendly tourer, or a plush long-distance highway machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
