Just got a '01 TTR225 for my daughter. The steel wheels have to go. Does anyone know if XT225 wheels and/or hubs are interchangeable? Could I swap wheels? I understand the rear brakes are different. Are there any aluminum rims available for the TTR? What about the front caliper? The XT has a two piston one - will it fit the TTR? Are the seats the same? What jetting is recommended for the airbox/pipe mod? Any help would be appreciated!
