ok, i've been riding for 8 years now, and racing for 4 of those years on a honda CRF250R. i'm about 5'9" and 140lbs. i can through around and handle my 250 pretty easily, and im thinking its about time to move on up. i want to get a '10 honda CRF450R. BAD. i've never ridden a 450 before, but a good friend of mine recently moved up to a '09 450 and he said the change isn't very big and that i should have no problem. we're both B class riders and i'm eager to get one for myself but some of my other friends can only say bad and negative things about the switch. saying things like it's too much power and that ill kill my self on it and stuff like that. i'm about to go to college and i want a bike that will last me a long time. maybe i'm just freakin myself out? any advice would be great. thanks!
