aprillia might just start to be the bikes  for supertwins

Looks like it's an A2 compliant smaller version of the RS660.  No details yet on engine capacity but they're calling it the RS457.  Make of that what you will.

probably make a good addition to Junior Supersport and it looks like a Yamaha R4 is also on the way.

Any enthusiasm for an Ultra Lightweight TT?  Loads of manufacturers that could potentially get involved

I think a small bike class would be great - hopefully they can fit it in.
