# What size tyre valve do I need?

This depends on your motorcycle or scooter.

Generally speaking all the Japanese motorbikes and scooters come with a TR412 11.3mm valve. Pretty much all the European scooters are 11.3mm including the Italian ones like Vespa and Piaggio.

Older Japanese bikes, pre 1990s, usually come with an 8.3mm valve and most modern European bikes come with an 8.33mm tyre valve.

There are obviously a couple of exceptions to this but if in doubt, give us a shout.
