And one of the biggest names will be Freddie Sheene, son of the late great Barry Sheene.
Freddie will be riding a Suzuki RG500 belonging to Steve Wheatman, just like his dad raced at Cadwell in the late 70s.
Freddie said: "I know Cadwell was one of my dad's favourite tracks and I'm really looking forward to experience what it was like for him to race a RG500 around Cadwell."
Freddie joins the rest of the stars on the Cadwell grid on August 3.
