Up for sale is a used OEM 6 speed wide ratio EXC transmission for a KTM RFS (Racing Four Stroke) dirt bike. This is the exact transmission found in a 2003-2007 400, 450, or 525 EXC or XC-W. These parts will also work in the RFS SX, MXC, XC, or SMR but your gear ratios will be changed. These parts came off a strong running 2005 KTM 525 EXC with only 22.5 original hours. Everything is in perfect working condition. There are some light cosmetic signs of use from normal operation. No excess or unusual wear, cracks, or damage. These parts need nothing and are ready to mount and ride. Look closely at the pictures. What you see is what you get!
