Realistically, the modifications done to this 2003 Honda CR250R were fairly minor. As some may forget, a two-stroke's power characteristics can be quite heavily affected just by adding a different pipe and some proper jetting. So in this case, the most major change was a custom made "works" cone pipe and silencer from Flow, with a jetting spec to match. This "works" pipe was made by Randy Blevins, who handed crafted many exhaust systems for championship winning teams. Beyond that, the engine itself was just rebuilt with an oem replacement piston kit from Wiseco, a V-Force reed valve from Moto Tassinari, and a complete clutch system from Hinson to handle a little extra abuse.
Since the bike was purchased at a fairly cheap price, this left a bit of extra coin to spend elsewhere on the bike. As for hard parts, the beefier wheelset came from Dubya, which consisted of Talon carbon hubs and Excel A60 rims. To go along with the wheels, Neutech's Tubliss system was mounted on both ends to add better traction to the Dunlop AT 81 tires that would be utilized. Last up, Galfer's rear wave rotor and 270mm Tsunami front rotor were added to help bring the bike to a halt.
The final years of the CRs weren't exactly the most popular when it came to handling, so a few steps were taken to try and get the best out of the bike. Ride Engineering's 22mm triple clamps were added to improve the handling, along with a re-valve and re-spring treatment from Enzo Racing to take away some of the harshness that comes from the CR's stiff chassis.
