120/90-18 Motorcycle Tires

32 models in 120/90-18, from 7 brands we stock. Order online for delivery, or have them fitted at the shop in Orange.

What 120/90-18 means

120 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 108 mm here. 18 is the rim diameter in inches — the wheel this tire mounts on.

On most motorcycles a 120/90-18 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.
