Complete NEW OEM Crate Motor:
A Rebuilt 2003 KTM 300 engine is no comparison to the reliability of a factory assembled Crate Motor. For most riders, rebuilding an engine isn’t needed if it is properly taken care of. For example, an expert-level GP rider put 600 hours on a 09 yz450f before needing a freshen-up. The point is that rebuilding an engine can be worse than keeping it all stock if not done correctly, and most don’t as to fully rebuild an engine will cost over this price, not to mention labor.

Craig –
I couldn’t find a complete engine for my fe501 when the shop put in the oil filter backward, so I showed the shop this, and they hooked it up with a factory-built fe501 with some fs450 cam and valves! 60hp on the dyno I’m stoked!
