The cush hub from KTM is a mix...there are three different hubs, backing plates and spacer combinations for three different years on the LC4. The first one I tried (for the '06 LC4) had the sprocket and rotor alignment correct but was too wide by about 7 or 8mm to fit. Basically, the sprocket carrier stuck out of the hub by that distance. I am still working on this trying to get the right combination. When I do I will post the part numbers for the right combination to go on the RFS (or on my 250 EXC 2-stroke, for that matter).
This summer I am planning on following the Pony Express trail from St. Joseph, MO to Sacramento, CA. Some of the trail is fenced off but some of it can still be ridden. I hope to head up to Prudhoe Bay in Alaska on the Arctic Ocean after that.
Your RTW trip sounds great! Need a mechanic / photographer to go along?
