just what the hell is a "street gp?" it wasn't exactly explained properly in the video. this could've been more....but the guy just chose to read off his parts list instead.
Street is for the bike's street legality and GP is for the bike's readiness for track racing, in short Street GP is a street legal track ready bike. the difference between the Circuit Concept and the Street GP Concept is that you can't use the Circuit Concept publicly or in public streets due to its missing important parts like side mirrors, plate number, lights and obviously registration.
