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 13 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.

A must have for people who do the majority of riding on the street...

I ride mostly on the street, and one of my first modifications was to buy dual sport tires for the factory 19" wheels. The dual sport tires was a decent compromise, but if more than 90% of riding is on the street it's definitely better to have a supermoto wheelset. I thought the dual sport tires were smooth. I couldn't have been more wrong. I highly recommend buying a set of supermoto wheels if the majority of your riding is on pavement. The only reason why I don't rate it 5 stars is the durability. I managed to break one of the rear spokes on my regular commute on these rough Southern California roads.

Super Moto Wheel set

The only reason I’m giving them a 3 star review is that the spokes and nipples are the same ones that come on the stock 19” wheels. Not the same length of course but the same 12 gauge ones found on the stock wheel set. Was hopping on finding a nice quality set of 13 gauge stainless steel spokes like it says in the description & not the same low quality spokes and nipples found on stock wheels. Still a good deal for the price and convenience this kit offers.
