I just got my new (old) xr500 yesterday. I had started riding on a 92 rmx250 about a year back. I'm 36 years old and don't ride really crazy. For my style of riding... getting rid of the 2stroke I think may be the best thing I ever did. The 4stroke is way more forgiving. On the 2 stroke it felt more like I had one chance to have the bike lined up before I cracked the throttle opened. I'm hadn't ridden my 250 in over 4 months and had no desire to. I had pretty much given up the sport. Now all I can think about is riding again. The 2 stroke made me feel like mabey I was in a sport I was getting a little old for. On my new xr I was smiling the whole ride.
