Iv'e owned over 40 bikes though the years and of lately rode a lot of 450s. sure they go like hell when ya ring um out but the 650 makes me grin when i roll the throttle and with a little suspension work I give them kids fits on the trail. It really gets them when ya pull behind them and honk your horn (mine has a dual sport kit) sure I could get a new 450 and go even faster through the nasties but i don't feel that need as much anymore.That just means when i do fall i'll just be going faster. besides hearing all the stories of 2-3 grand.on a blown 450motor kinda keeps things in reality. I've heard 650's going 10,000 miles before rebuilds. 10,000 miles if it's purely just raced but if it's a street leagl job not beat on you should be able to easily X's that by 3 or 4 ......... No - Yes ?
