YAMAHA WR250R SUPERMOTO CONVERSION GUIDE:
The beauty of dual sport bikes like the Yamaha WR250R is that it can be two bikes in one... with the stock knobbies, you have a very capable 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 Yamaha WR250R 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 sticky supermoto tires like the Bridgestones or Dunlops 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. You also need to source a shorter kick stand.... we just ordered an OEM kickstand from a 2008-2011 WR250X Supermoto, which is an inch shorter and will bolt right on.
As for a rear sprocket, the gearing you choose is a personal preference type of thing, but on our bike we went with a 42T rear sprocket, which also happens to be what the WR250X Supermoto's came stock with.
WR250R Supermoto Wheels:
We use Warp 9 Supermoto wheels on all of our supermoto conversions. Their wheels are available in a lot of different color combinations, and they will include a rear sprocket as well as front/rear brake rotors.

WR250R Supermoto Tires And Tubes:
For the WR250R we like the following tires from Bridgestone and Dunlop. Both are available in a 110/70-17 front tire, which is what is recommended for the WR250R. Some will run a 120/70-17 front from other brands, but we've heard of rubbing issues on the front forks with that 120 tire, so we stick with 110's on our bike.
Bridgestone S20 Evo Hypersport Front Tire (110/70-17)
Bridgestone S20 Evo Hypersport Rear Tire (140/70-17 or 150/60-17)
Dunlop Q3 Plus Front Tire (110/70-17)
Dunlop Q3 Plus Rear Tire (140/70-17 or 150/60-17)
Michelin Front and Rear Inner Tubes
Other Things To Consider:
Changing to 17" tires will throw off your speedometer/odometer, so we recommend recalibrating it with this nifty product from 12oClockLabs...
