FAQ

What axle size does it fit?
Both 12mm and 15mm. Spacers for 12mm axles are included.
What are the rim sizes?
2.50 x 12" front and 3.00 x 12" rear.
What front tire does this set use?
A 90/90-12 street tire. If you want more front-end handling, see our Wide 110 set.
Which chain side and sprocket do I need?
Sit on the bike facing forward and check which side the chain is on. Then match your current chain size and sprocket.
Why not just ride my knobbies on the street?
Knobby tires are built for dirt. On pavement only the tips of the knobs touch the road, so you get less grip in corners and under hard braking, and the knobs wear down fast. Street tires put a full, solid tread on the asphalt for more grip, better braking and a smoother, quieter ride. If you ride mostly on pavement, supermotos are the right setup.
