Can anyone compare the power of a 2011 te310 to a 2004 or any yz250f that has been bored to a 310? I'm hoping the te would be just as powerful and not a step down from my yz250f with the oversize. I really like the bike and the plate that goes along with it. How fast is comfortable and will not blow up the 310 on the roads? Some connecting roads have speeds up to 40 mph and I was wondering how it handles it. I mainly ride tight single track, rough wood trail rides, and hope to get back into hare scrambles. Roads that connect trails may be like 3-5 miles at times. I don't want the 449, too much bike for me and the type of riding I do. Thanks in advance.
