I was waiting to get an aluminum frame YZ-450, I have rode a lot of 450's but finally decided to put the 2-stroke away and get a new bike. I really wanted the new frame but got such a good deal on the 05 I could not pass it up. I was sad about giving up my 2-stroke and was kind of not excited about the deal as this is one model I had not ridden much. I must say I was pleasantly surprised Sunday, this bike is much better than I thought it could be at race speed. The bike felt much lighter in the air than expected and with the offset clamps I put on it turned so much better than stock. Already do not miss my 250 smoker and can't wait to get the suspension done and try it then. Only thing I did not like was the super long stock exhaust , it runs well but I would catch a glimpse of that chrome tip sticking out there and think some one was running up on me. Got a DR D comming.
