| Hiya,
I raced my 583 in many Class A / mixed grid races over the last two seasons - you will not have a problem whatsoever. A lot of the riders in both classes are evenly matched, so theres lots of mixing it up. At the faster tracks like Snetterton and Donny then you will notice the Class A advantage, but at places like Mallory it will be less noticeable.
You wont win the Class A championship on a Class B bike, but you could have a decent run and a lot of fun.
Oh, and as it happens I have a DD Class B bike for sale if you are looking. Its very tidy and looking for a home. :-) Its listed in the Ads section.
PM me if you are interested.
