I have to agree with both sides. Personally-- I don't take pit bike racing seriously. If I was going to get serious about racing, I'd get a 250F, and race the Senior II races. I just like to get out and do some ridin', have a good time, and get back home in one piece--- AND I don't want to spend the chips on the 250F, nor do I want to stick my neck out racing the bike. Pit bikes are all the fun, but a fraction of the risk or the cost. That's my take.
On the other hand-- pit bikes IS still a race. if you are one of the many who take pit bike racing seriously, then some structure would be helpful. What I've always thought was strange, is that the rules have everything to do with wheel size, and NOTHING to do with the engine in the bike. Every other motorsport is engine power based. I have no idea who made up the pit bike rules.
A 150R? Naw. I wouldn't let it race.
At the Briarcliff track- a 110 has an advantage over the trail bike. The track has been too tight fir the bigger trail bikes lately.
J- the Trail Bike races are just for kids. They don't let adults race in it. It would be cool to have an adult trail bike race though at the CRA races. --L*64
