How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's a supermoto-styled small-bore machine best used for zipping around town, learning street-oriented riding skills, and light-hearted fun rather than serious speed or genuine off-roading.
- Built for
- It has a playful, nimble character with sporty supermoto looks, modest but adequate power for its class, and confidence-inspiring, tossable handling.
- Not ideal for
- It is not the right choice for experienced riders wanting real highway speed, long-distance touring comfort, or hardcore off-road capability.
