Those of you that ride XR650's in heavily wooded trails, how do you rate them? Are there any of you or know anybody in their 40's or 50's that ride these in heavily wooded trails? Do you think their great or would you rather have a smaller, lighter bike? I know a Reklus auto clutch would make riding easier but my concern is, does the power output and weight of this bike wear you out? Appreciate your inputs!
