Rider Profile
| Best For | This lightweight two-stroke suits newer riders or those who enjoy small, revvy bikes that reward frequent gear changes. |
| Purpose | Built as a nimble sport commuter, it's best for spirited rides through twisty roads and city streets rather than outright speed. |
| Rider Fit | Its low 115 kg weight and compact dimensions make it easy to handle for riders of almost any size or strength. |
| Character | A classic buzzy two-stroke single with a playful, high-revving character that rewards an active riding style. |
| Not Ideal For | Not suited for riders wanting high top speed, long-distance comfort, or serious off-road capability. |
