120/70-21 Motorcycle Tires

7 models in 120/70-21, from 5 brands we stock. Order online for delivery, or have them fitted at the shop in Orange.

What 120/70-21 means

120 is the section width in millimetres, measured across the tread. 70 is the aspect ratio: the sidewall is 70% of the section width, which works out to roughly 84 mm here. 21 is the rim diameter in inches — the wheel this tire mounts on.

On most motorcycles a 120/70-21 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.
