I have been reading about different ways to effectively break the bead on the KTM rims, especially since doing it myself the old fashioned way a few weeks ago. I have changed tires on bikes dozens of times using the jump up and down on the tire with your heel and use your sweat as lubricant technique untill I read some of the treads on bead breaking here. Thank you , thank you, thank you Decided to try the cheap way first. Got a 5 inch C clamp from Harbor Freight tools for $3. Proceeded to break the bead on a Dunlop D908 in about 30 seconds. Worked like a charm! The nice thing about this way is that I may even be able to make a repair to the tube, out in the field without dismantling the entire rim. I'll have to see. Attached are the photos. I think this would work well with the scorpions too.
