I switched from the XR to the KTM to the Husaberg FE 570. There is no comparison between the XR and Husaberg. The Husaberg is "Light Years" ahead of the XR. You're gonna love the Husaberg. Yeah, the maintenance is a little more intensive, but not all that complex. You will now have screens to clean when you do an oil change, you'll need shims to adjust the valves, the oil you use will always be a full synthetic, and you'll immediately want to install the Can Am filter in the fuel line to avoid injector issues. What you gain is a lot of power, tons better suspension, and brakes and handling that actually work. You'll love it. Add a 70 degree subframe tank and you'll be at I believe 3.3 Gallons on board. I added that to mine and have done 156 miles without running out. The low fuel light was on, but it made it home.
My KTM madde over 35,000 mile off road, and I expect this Husaberg should do the same with the proper maintenance.
