I'm in the market for a new bike. Reliability and low maintenance requirements are my considerations. I have been looking at the 06 Honda CRF450 as well, but it looks like there is a lot of maintenance involving the valves, water pump leaks, clutch basket, fork stops, frequent piston ring replacement. Don't get me wrong you CRF450 owners. I think the bike is awesome, but I don't like to spend a lot of time on maintenance, and I don't have excess money to spend on parts. The YZ450F seems fairly maintenance free and pretty dang reliable from all of the threads I've been reading. Only problem is the price. The dealers are telling me that there is a limited supply of them, and they are fairly hard to get, thus expensive. I've gotten quotes of $7500-$8000 out the door. What do you owners of the 06 YZ450F think of the bike so far? Any problems? How much did you pay? Thanks in advance for you input.
