| 'RACING CONICAL' 4-1 or 4-2-1 CONFIGURATION The Akrapovic Racing range of systems are designed to give maximum power increase to standard and tuned motorcycles alike. The Racing range feature conical header tubes and crossover tubes where appropriate. This optimises mid range power increases without sacrificing any peak power gains. The most appropriate application for these systems is to maximise power increase for professional race use or mildly tuned engines. |
