What the numbers mean
The 775 mm seat is a middle-of-the-road height: most riders will get the balls of both feet down.
At 104 kg it is light enough to push around a workshop or park by hand.
The 5.6 L tank is typical for the class and enough for a week of commuting between fills. The manufacturer does not publish a consumption figure, so this page does not quote a range.
Tyres are 120/80-12 65J front and 130/80-12 69J rear. Check that your local shop stocks both before a long trip. Small rims are less widely stocked, so confirm availability locally.

Ownership and maintenance notes
- Clean and lubricate the chain at short intervals in rain or dust, and check slack with the bike on its side stand. A loose chain wears sprockets quickly; a tight one loads the output bearing.
- Check tyre pressures cold. On a light bike a few psi matters more than it does on a car, and it changes both steering and tyre life.
- Air-cooled engines rely on clean fins and a clear path for air. Wash the fins gently, and do not let mud or a loose cover block them in traffic.
