I have a 2006 KTM 450 that has been converted to a 520cc engine. I still have the original parts from the 450cc model, along with the factory suspension. The current suspension is set up for a rider weighing 250 lbs.
Please note that the bike may need a new wiring harness (it was repaired on the trail) and a new chain guide for the front sprocket. The bike ran perfectly fine before being stored, and it still operates well. I started in the summer with no problem. It comes with plenty of aftermarket parts and is street-legal.
The bike has approximately 4,500 miles on it, with around 1,000 miles since the rebuild. I am selling it AS-IS, $2,500 OBO Cash only
