Newbie question

[Golightly]

What are the typical classes for the SV650? 
Looks like they fit into several, but I assume there are typical classes in which they run and can be competitive?

My first time racing will be Sep 20th -21st at VIR. 
Will only be racing LW F40 on an SV650, so far.

Pretty much anything other than ultralight weights and 125gp.

Around the midwest they usually are in lwss, lwsb, lwgp, thunderbike where they are best suited. They run fine in supertwins except on large tracks wher 1000cc twins can get a scooting.
