Selling our Pro Senior due to second boy outgrowing it. Bought it new Dec '02 , and have owned it since and done all the work on it myself. KTM did not make enough improvements since '03 to justify me buying a new model, so I jut kept this one and kept improving on it. Every Pro Sr issue you have ever heard about over the last five years has been addressed on this bike....If you are looking for a 50 that is truely race ready, and are serious about racing and not having to work on the bike between motos, you need to look hard at this bike. I have tried almost every setup combo out there over the last 5 years, and will asure you that you will not be disappointed with how this bike runs. This bike has pulled holeshots at Loretta Qualifiers...and has been my pride and joy for a long time! The engine was rebuilt at the end of '06 season, and only has one race on it. The bike ran very little in '07...( a couple trail rides to be exact)...I was holding onto the bike for a friend, but need to pick up an 85 this spring for oldest boy....
Model improvements were applied to this bike, including the '04 water pump drive, '05 stator, and '06 & newer clutch drum. It is not a "Mod Bike" , it is an extremely good running 50, that is extremely reliable. Although, the OEM swingarm, etc would have to be reinstalled in order to enter a Loretta's stock class qualifier....
