100/90-12 Motorcycle Tires

5 models in 100/90-12, from 4 brands we stock. Order online for delivery, or have them fitted at the shop in Orange.

What 100/90-12 means

100 is the section width in millimetres, measured across the tread. 90 is the aspect ratio: the sidewall is 90% of the section width, which works out to roughly 90 mm here. 12 is the rim diameter in inches — the wheel this tire mounts on.

On most motorcycles a 100/90-12 is a front tire.

The sizes listed for each model are the sizes it is made in. Confirm against the size on your own bike before ordering — wheel swaps change fitment.
