A production bike can be converted into a superbike for racing by making a few modifications. These modifications include reducing the weight of the bike, improving the aerodynamics, fitting better tires, and upgrading the engine to increase power. Suspension, brakes, and exhaust systems can also be improved. All these modifications will help the bike to handle better and increase its performance. Finally, the bike needs to be tested to ensure that it can handle the increased power and speed.
