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

Converting a CRF450L to a supermoto is pretty straightforward. All you really need is a good set of 17" supermoto wheels like the ones we use from Warp 9 Racing, and then some sticky tires like the Dunlop Q3+ 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 the front tire doesn't rub. On some dual sports, you need need to source a shorter kick stand so the bike doesn't stand straight up with the kickstand down.... but with the CRF450L, you don't need to, and the stock kickstand works just fine. As for a rear sprocket, the gearing you choose is a personal preference type of thing, but on our bike we went with a 50T rear sprocket initially, which is one tooth smaller than the bikes stock rear sprocket. We're now running a 46T and like that much better.
