70/100-17 Motorcycle Tires

12 models in 70/100-17, from 6 brands we stock. Order online for delivery, or have them fitted at the shop in Orange.

What 70/100-17 means

70 is the section width in millimetres, measured across the tread. 100 is the aspect ratio: the sidewall is 100% of the section width, which works out to roughly 70 mm here. 17 is the rim diameter in inches — the wheel this tire mounts on.

On most motorcycles a 70/100-17 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.
