HONDA CRF450L / CRF450RL SUPERMOTO CONVERSION GUIDE:

The beauty of dual sport bikes like the Honda CRF450L/RL is that it can be two bikes in one... with the stock knobbies, you have a very capable off-road and dual sport bike, and by adding a set of 17" supermoto wheels and tires, you can also have a capable corner carver for the street or kart track.

What You'll Need To Do:
Converting a Honda CRF450L/RL to a supermoto is pretty straightforward. All you really need is a set of 17" supermoto wheels like the ones we use from Warp 9 Racing, and then some 17" supermoto tires like the Dunlops or Avons we use (see details below). There are a few things you need to do to fit the smaller 17" wheels/tires. Up front, in order to clear the smaller 17" supermoto tire, you have to re-route the front brake line to the outside of the fork leg and also trim the plastic lower fork protectors so they clear the front tire. One bonus with the 450L.... you won't need to source a shorter kickstand like you do on most supermoto conversions, to accommodate the 17" wheels/tires... the stock CRF450L/RL kickstand seems to work just fine. Please note, that if you've lowered your bike with a lowering link, and you convert to a supermoto, then that kickstand will be an issue and the bike will sit more straight up than you'll want it to.

Gearing:
What front and rear sprocket size you choose to run on your supermoto is a personal preference type of thing, and really does depend on the type of riding you do. On our supermoto project bike we initially went with a 50T rear sprocket but the bike was turning too high RPM at higher speeds. We have since switched to a 46T sprocket (with stock front sprocket size). We ride mostly twisty back roads with speeds topping out around 60-65mph, and the 46T works nicely. On another one of our CRF450L SM project bikes, we did a 44T rear and I really liked that as well.

Speedo/ODO Calibration:
If you purchase our Warp 9 supermoto wheels, they will include a ring that mounts to the brake rotor that the speedo/odo sensor reads from, and this will keep your speedometer and odometer accurate. So there is no need to re-calibrate it once you install your new wheels.

We use Warp 9 Supermoto wheels on all of our supermoto conversions. Their wheels are available in many different color combinations, and they will include a rear sprocket as well as front/rear brake rotors. They offer traditional spoked wheels requiring tubes, spoked tubeless wheels, and also a forged aluminum mag style tubeless wheelset as well...
