How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Best suited to spirited urban riding and short scenic jaunts where its light weight and unusual four-cylinder character can be enjoyed at legal speeds.
- Built for
- A quirky, high-revving miniature four-cylinder that trades outright performance for mechanical charm and a distinctive exhaust note.
- Not ideal for
- Not for riders seeking real touring range, passenger comfort, or motorway-speed confidence, given its tiny fuel tank and modest 156 km/h top speed.
