I like V6LW as a class the best. I get to practice and race while the light weight modern stuff is on the track. Since I'm on my RZ350 this keeps things interesting. Also the lighter bikes are most fun to me. The most powerful bike I have been on a track with was only 90 HP so maybe I haven't had the big bike experience but I love the light bikes. If you're older I heartily recommend trying light weights. Just getting them in the trailer or putting on tire warmers is worth the change!
