IN THE WIND P30 NORTON DEVELOPING SUPERCHARGED 650 TWIN! N orton's Executive Director and Head of Design Simon Skinner has hinted the iconic British marque is considering supercharging its yet-to-be- released 650 parallel-twin. Skinner made the comments while chatting to Cycle News about the 1200cc V4 superbike project, due to be first shown to the public at the NEC Show in Birmingham, UK this November. "Stuart [Garner, Norton CEO] has ideas about supercharging the 1200 V4, but we in engi- neering want nothing to do with that¾we'll give it to someone else to do as a relevant little project aimed at absolute perfor- mance," says Skinner. "Super- charging the 650cc parallel- twin spinoff from the 1200 V4 is much more interesting and rational, and we're working on that right now. A bike weigh- ing 150kg (330 pounds) with 170 bhp from a supercharged 650 twin would go like stink, as well as being environmentally friendly, and better on fuel and emissions. "The great thing about modern-day supercharging is that you can have variable boost controlled by the ECU. You put loads of boost on as standard, then bleed it off and on as you need it, but you do it electroni- cally. We looked at turbocharg- ing as well, but it's that worry about the throttle response and the ability to get it off the line that deterred us, plus the issues of greater heat and bulk com- pared to a mechanical super- charger." Should Norton indeed follow through with the promise, it will join Kawasaki as the only cur- rent manufacturer (H2 and H2R) to have a production super- charged engine available to the public. Alan Cathcart Skinner (pictured here) is confident the 650 supercharged twin will be a massive success. HONDA 300s RECALLED O wn a Honda CBR300? Then listen up.
