What 120/70-18 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. 18 is the rim diameter in inches — the wheel this tire mounts on.
On most motorcycles a 120/70-18 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.Every 120/70-18 tire we stock
