GP45 is the Next Generation of racing motorcycles and they're now being supported by NG Road Racing. These 450cc single cylinder racers have been given special dispensation to allow 15 year olds to race them proving how serious the ACU are taking the class into the future. They make the perfect transition between 125cc and 600cc as a genuine race bike. The GP45 transforms a 450 single motocrosser into a GP-inspired racer with no permanent changes allowing the bike to return to it's MX form.
