Thought I'd give this SuperMoto thing a try this summer. In short I want to keep the cost down by just getting the tires only for the stock 21" and 19" on the CRF450. My real forte is racing harescrambles but I'm game to try something new. If I like it maybe I'll buy a second bike just for supermoto but for now I wish to keep it cheap and simple. Things to consider are that the track in Circleville OH is a asphalt and dirt. I just couldn't imagine trying to get through a dirt section on slicks. There is some talk being thrown around for building a asphalt/dirt course about 5 miles from my house and thus my interest in the sport.
