What the numbers mean
The 762 mm seat is a middle-of-the-road height: most riders will get the balls of both feet down.
At 114 kg it is manageable at walking pace but heavy enough to notice on a slope.
The 4 L tank is small, in keeping with a short-range commuter; expect regular fuel stops on longer rides. The manufacturer does not publish a consumption figure, so this page does not quote a range.
Tyres are 70/90-17 38P (Tubeless) front and 80/90-17 50P (Tubeless) rear. Check that your local shop stocks both before a long trip.

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.
- Liquid cooling adds a coolant level and condition check. Do it when the engine is cold, and never open the radiator cap on a hot engine.
