What 90/90-21 means
90 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 81 mm here. 21 is the rim diameter in inches — the wheel this tire mounts on.
On most motorcycles a 90/90-21 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.Every 90/90-21 tire we stock
