How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed as a supermoto-styled commuter and playbike for short urban and suburban trips rather than serious performance riding.
- Built for
- Nimble, light, and eager-revving, it rewards flicking through traffic and tight corners rather than outright straight-line speed.
- Not ideal for
- It's not the right choice for highway touring, carrying a passenger comfortably, or riders wanting real power on tap.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
