I just attempted to mount the KTM Hardparts full chasis skidplate on my SX....but it didnt work. At the rear of the plate it has tabs that slip around the frame rail behind the engine (just like the stock plastic one) but the tab that goes between the frame rail and the engine cases is thicker than it is on the stock plastic one, so it doesnt fit. It just barely hits on the cases. I think I'll just cut off that tab since its not really necessary. Just wanted to give everyone a heads up.
