Well how about a Twins Triples and Singles Class .I think it is one way to go all you had to do is look at Mark Millars results from TT 2007 on a European Twin. When you list the Manufacturers who produce Twins Triples and Singles their are quite a few . Ducati . Aprillia . Mondial . BMW . KTM . Triumph . Honda . Kawasaki . Yamaha . Suzuki . Buell . CCM . Voxan . Hyosung . they are the only ones i can remember at this time. As i said in an erlier post you could split them into to 2 classes.

Class one for Unlimited Twins up to 1450cc with Triples to 1000cc and Class 2 for Twins to 750cc with Triples to 675cc and 900cc Singles let them run after market Chassies and the like it would be like a prototype class or call it Extream Twins Triples and Singles just a thought for now..... cheers Irish Ago...
