AHRMA sidecar rules are a bit odd, and the unfortunetly the sidecars don't get much love down here in the states. Whether it is practicing with the bikes, races getting cut short, or being sent out in the rain when they dont wanna run bikes.
I would consider putting my gt750 engine in a three wheeler if it were worth my time, but it isnt. I would want a two stroke and, well, the rules kinda kill that for cool stuff.
We are trying to convince all our AHRMA friends with rigs to come to mosport. They appear to get treated MUCH better up there.
