Can this be done? I want to add the dig speedo to my 500tbx but didnt know if it could be done? Thanks

 

If you can find an analog system that is run off a front wheel, probably. Most of the digital are run off a sensor on the tranny. This kit might work if the wheel assemblies are the same on the '05 250 and your machine. You need to go into here and compare part numbers on the front wheels.
