I have been a 2stroke rider all my life, currently rebuilt an 03 cr250 from ground up, it's my baby. I will never part with it. But the stable needs an open class honda, 500s are expensive now that the previous owners know everyone at least wants the engine, so that's out, plus I raced those for my teenage years. I got burned on a yzf450, probably due to me treating it like a 2 stroke and not doing valve maintenance which ended with horrible bills. Ahhh, quite frankly im gonna get a crf450. My question is not based on 2 vs 4 or any of that, it's towards people that have rode during the 2stroke era, and have adapted to the 4 stroke era. Will serious minds tell me if a 450crf is okay to be considered an open class machine, can it be compared to open class power. If I won't have a machine that is not more torque oriented then the hypo 250 I have I will simply save my money, but I want power and a change from my little 250. As I said, the cr stays, but will the crf be an addition or not anything noticeably different then what I have. The 04 yzf was cool but I'm only doing Honda, so someone set me straight.
