A 160-170bhp Yamaha R1 isn’t, of course, fast enough for some people. Which is why there are NOS kits, turbochargers and superchargers in this world. And, right on cue, here we have a late-model carbureted Yamaha R1 fitted with a Rotrex supercharger, with the engine producing around 200 horsepower. At least now it should be fast enough for most people…The Rotrex supercharger kit consists of the charger unit, engine cover, drive belt, oil cooler/oil container, oil hoses, intake tubes, air filter, plenum chamber, blow-off valve, carb mods, bigger fuel pump, fuel pressure regulator, two head gaskets and modified exhaust. Other mods include an Akrapovic exhaust, Brembo brakes with four-piston radial-mount calipers and high-spec Ohlins fork and shock.The owner says the bike is running very low boost, so does not need fancy new pistons or cranks. ‘It starts on the button every time and is a joy to ride. I’d recommend this mod to everybody. It is a complete pussycat if you want it to be, or an animal at the twist of the wrist. There is power everywhere…,’ says an obviously very happy R1 owner.Including labour charges and seup, the R1 supercharger kit cost US$7,000. Maintenance routine is said to be the same as that for a regular R1.
