I looked it up, but I couldn't find a list of eligible bikes.
Perhaps it is a modern class which doesn't require vintage pedigree or design, and in that case the AVL Bullet could participate. The AVL is not eligible for any vintage class racing because it is a modern bike.
If it is a modern class like Super Mono, then you will be up against all the modern singles under 610cc, and that could be pretty stiff competition, because they will alol have at least twice or 3 times the hp that you have.
