I will have the lt on a 300 soon. I believe it will be enough power and torque, the 300 with a st does a lot of track spin in my opinion. I feel the 300 is more suited to load than free rev. My personal 300 is built to rev as much as possible without using the domed piston conversion. That might be the next level though. A true sx, with the gas gas domed piston conversion, running on straight 110 leaded. I hate to admit it but after riding in some really deep condition I am admitting that a e start is awfully nice. Hard enough to get on the bike in 60" of fluff, much less kick the sob. I know one thing for sure, the 300 feels so quick and light compared to a 450 or a 500plus four stroke. Time will tell.
