How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as an everyday naked bike for commuting, learning, and spirited weekend rides rather than outright performance or long-distance touring.
- Built for
- A friendly, revvy parallel-twin street bike that rewards playful riding in town and on twisty backroads without being intimidating.
- Not ideal for
- Not the right choice for riders wanting serious highway touring comfort, passenger-friendly long trips, or any genuine off-road capability.
