Sur-Ron Super Moto Conversion Kit


Current stock: 0

This is the complete bolt on kit you need to turn your Sur Ron into a super motor dirt bike.  Note the Sur-Ron bike in the pictures is not included.

  • Complete built wheels and tires
  • 203mm brake disks
  • 42 tooth Sprocket
  • 420 chain at the correct length

We wanted to make it easy for anyone to convert their Sur-Ron Firefly bike to a Super Motor road bike racing bike.

This is a bolt on kit where anyone can quickly convert their Sur Ron in their own garage, as easy as swapping out the wheels. (less than an hour job).

That is because we even include the sprocket and chain, you will need to get to road worthy gear ratio. 

This will make your stock Sur Ron MX bike into the supermoto road bike that is lower to the ground and look more like a bicycle.

The tires are road tires which have a completely different look than the knobby tires. 

Because this kit includes both a 42 tooth sprocket and a properly sized chain, you will still get the same top speed as the stock MX bike.


The tires and wheels are designed for the Sur Ron to make it super moto worthy:

CST 3 ply nylon tread and 2 motorcycle level tires DOT. Front 70x90x17 Rear 90x80x17

Rims are alloy DOT  Front 17 x 160   Rear 17 2.15

The kit has the exact same hubs that come on the stock Sur-Ron. 20mm thru axle front and 15mm rear.

Quality built wheel with strong 12 gauge stainless spokes and nickel plated brass nipples. Dimpled nipple exit on rims.



Support notes:

If you have the Rockshox Edition Sur-Ron you will have to remove the front brake rotor off the dirt wheels and take the the spacer (between the hub and the disk rotor) and  the longer bolts and install them over the super moto front wheel. The alternative would be to buy another disk brake spacer (called a boost axle conversion) and install it permanently on the super Moto kit.
