Tyre pressures
Tap your bike and the old pump does the rest. All values come from the original owner’s handbook or workshop manual.
Note: these values apply to the original tyre types. If you ride on modern tyres, also check the tyre manufacturer’s advice. Always measure with cold tyres, before you ride.

Good to know
- Old handbooks often give the pressure in kg/cm² or atm. That is almost the same as bar: 2.0 kg/cm² is about 1.96 bar.
- Measure cold. After a ride the pressure is higher; do not let air out then.
- If you ride with a passenger or luggage, use the “with passenger” value.
- A good tyre pressure gauge costs little. Check the pressure every two weeks, and before every long ride.
- Also look at the age of your tyres: the DOT code on the sidewall shows the week and year of manufacture.
Is your bike not listed? Send a photo of the tyre pressure page from the owner’s handbook to info@classicmotofix.com, with make, model and year. Then we will add it.
