Icon Motorcycle reveals Barry Sheene tribute
News Icon Motorcycle reveals Barry Sheene tribute LONDON, UK: New manufacturer Icon Motorcycles has launched a limited production bike as a tribute to the late Barry Sheene. The British motorcycle champion has long remained an icon in the public mind that has lingered long after his death through cancer seven years ago. The brain behind Icon Motorcycles is Andrew Morris who made his fortune in the shipping industry. It was on a rowing trip across the Atlantic in 2005 that he came up with the idea of the Icon Sheene motorcycle. “For about a year and a half following that it was no more than a concept in drawings. I showed them to Steve Parrish, the 500cc World Motorycycle champion in 1976, and Barry Nutley, the radio and TV commentator, both of whom were close friends of Sheene, which led me to getting in touch with Stuart Tiller of Spondon Engineering. This, in turn, led to more contacts so that by the end I had around 20 core contacts who all got involved in the project in one way or another. Everything about the bike is bespoke from the handbeaten aluminium fuel tank to hand-blown glass HID headlamp and from the keyless ignition to the handmade swing arm with unique integral polished hugger and axle lifting system. The bike is powered by a By William Kimberley turbocharged Suzuki 1400cc engine that delivers 257bhp at the wheel and 133 lb ft of torque. “We’ve set out to make the bike quick and powerful but also going back to technology that was around in Barry’s era,” said Morris. “So what we’ve done is mated up a Garrett turbocharger to the last of the really strong oil and aircooled GSX motors, with which Barry would have been very familiar. However, we’ve stripped everything out of it, put in Wiseco pistons and Carrillo conrods, replaced the cams and valves, oil pump and clutch and have had some engineers make all the oil coolers. Using a MoTec contol system and hours of research and dyno time, we have managed to make the engine more manageable and linear so that the turbo doesn’t suddenly cut in with a surge to spit the rider off in mid-corner. Instead the turbo starts to spool up as low as 2,000-2,500rpm making it a very tractable and rideable bike.” active in British and World Superbikes, who did the install for us.” Unlike the engine, though, the 6-speed gearbox has not really required any attention. “It is bullet-proof,” said Morris. “We know of identical engines to ours that have run up to 400bhp and we are at 257bhp.” The bikes has Bitubo front forks and Öhlins at the rear, but the final decision has not yet been made as to which suspension setup will be the preferred choice. “In fact, we’ve advertised it with Bitubo but when we ran it with Öhlins all round, it was also very good,” said Morris. Hydroforming gives a unique seemless bend, the difficulty about the process being that there is only one machine in the UK, so Morris has had to look further afield for a supplier for his exhaust boxes. “The down tubes and all the turbo pipes, though, are all hand-formed by a current Formula One exhaust engineer. We are also running with only a minute silencer because the turbo damps all the noise out. The bike is rorty but not illegal.” Eight months to build but each frame is made to suit the individual buyer, the information fed back to Spondon Engineering that will be making the 52 chassis – each one having its unique playing card logo carefully hand painted onto it. Other design features include the handmade solid silver Daffy Duck logo, a Barry Sheene trademark, and the signature of Sheene and his wife Stephanie on the top yoke. “Even the pressure from the pen supplied has been replicated in the CNC machine with variable depth.” The levers are all multiple adjustable for reach and pressure, the switchgear inbuilt into the clamp. “The have been made by Acke Rising who used to race against Barry in the ‘70s who wanted them on his bike but he wasn’t allowed to do so. Acke runs ISR Brakes in Sweden and he has made the brakes just for us.” Deposits are currently being taken for the £107,000 bikes which are being built to order. The only bikes not being sold is the seven of hearts, the current show bike due to the demands being placed on it. Modern touches Another modern touch is the use of data cabling rather than wires to keep the weight down. “It cost thousands just to have the loom laid up but it has been worth it just to eliminate a great deal of the wiring.
