I have an XB12X. For the most part it's a great bike, but it doesn't really fit what I want. I want a highly capable off road/long distance tourer. Like a KTM 990 minus 75lbs I guess. This would necessitate changing pretty much everything except for the frame. I want to use a Ducati 848 Streetfighter engine. It has a decent valve adj./maintenace schedule. A hydraulic, wet clutch, boatloads of power, and as far as I know no huge reliability issues. Its also relatively light and I'm pretty sure it will fit in the Uly frame. I'm worried most about the output sprocket location and front tire clearance. Ist gear is probably going to be way to tall as well. As far as chassis setup goes this ones a doosey. To get proper steering geometry I think I would have to tilt the entire frame back 3 degrees or so. This would give me approx 26 degrees of rake (with a triple clamp parallel to the steering head) and allow me to use a lower swingarm angle. It would also lower the seat height slightly (I want to fabricate my own subframe to give me a lower and slimmer seat) and keep the wheelbase shorter. I'm a little worried about seat height because its near the limit for me already (I'm 6' w/ about 33" inseam) and adding 4" of travel without keeping the seat close to where its at now puts this whole project in the toilet. I'm going to try to do this with off the shelf stuff as much as possible. So a new front end, ideally 50mm WP's, but probably just a re-valved, re-sprung 450 dirtbike setup. I have an idea for an adjustable braking system that I want to try out. It should allow the ability to change the power and braking feel to suit the road surface. I might be able to use the stock subframe with some modification. Ideally, I want about 8 gallons of fuel capacity and I don't think it's possible to add a 3.6 gallon tank to the stock subframe, but I don't know. I would have to work out the upper shock mount and the electrical stuff before I'll know for sure. For the swingarm I would focus on getting the angle and length right. I want around 10" of travel. Again, hopefully I could use the swingarm from another bike but I don't know how likely it is I'll be able to find one. I'm still undecided as to if its worth it. No doubt if i pulled it off it would be one hell of a bike, but if I sold the Uly and got a KTM 690 Enduro I would have one hell of a bike and I wouldn't need to do a complete engine and susp. swap. The KTM would also handle better off road. The KTM wouldn't be near as fast on road or in a straight line and would still require some work before it could go long distances comfortably. I can't decide so I figure I would put this out here and see what others think.
