Rider Profile

Best ForWell suited to newer riders and those upgrading from smaller commuter bikes thanks to its approachable power and light, predictable handling.
PurposeDesigned as a versatile single-cylinder roadster that excels at city commuting, weekend cornering fun, and learning the ropes of a bigger machine.
Rider FitA low seat height and manageable 170kg wet weight make it accessible to riders of varying heights and confidence levels, including shorter riders.
CharacterFeels like a modern, torquey single with a premium chassis feel, upside-down forks, and radial brakes giving it a sportier edge than typical entry-level bikes.
Not Ideal ForNot the right choice for riders wanting serious long-distance touring comfort, high-speed motorway cruising, or genuine off-road capability.
