News Patents Reveal Production Turbocharged Suzuki Recursion

Discussion in 'Motorcycling News' started by NetriderBot, Apr 9, 2015.

  1. Just a few months ago, there was a flurry of news surrounding the turbocharged concept Suzuki showed off at the 2013 Tokyo Motor Show. Firstly, Japanese magazine Young Machine claimed the bike had been confirmed for production. Days later, it was discovered that that Suzuki had re-registered the Katana brand name and logo in Europe and the United States. The Recursion has a passing resemblance to the original Katana, a bike which was the fastest production motorcycle in the world at the time.

    Now, Suzuki has filed new patents for the Recursion, but with a change to its looks that brings it from concept to real world. There’s no reason for Suzuki to file new patent applications with such a change in appearance unless production was going ahead.

    The biggest change in looks is at the front of the machine. Gone is the sleek, futuristic and no doubt expensive face and replaced with a more generic headlight and windscreen arrangement. No doubt part of that is to bring costs down and another is to do with the intercooler – it will need as much air as possible to suck down, and hence as big an inlet as possible is required – function over form.

    From the patents, it appears that the air goes into a tube which splits in two, goes around the steering head and then onto the top of the engine. The turbocharger is positioned in front of the engine and connected closely to the exhaust headers. The engine itself is revealed as a single overhead cam unit, making it lighter and smaller than a double overhead cam power plant. That’s not because Suzuki is trying to be cheap, it’s because with the turbocharger added into the mix, high revs aren’t required for power delivery and therefore a second camshaft would be prove mostly unnecessary.

    Like the concept, the patent shows that the aluminum frame goes over the engine instead of beside it, keeping the bike narrow. And if previously leaked documents still hold true, The Recursion/Katana will produce 100 hp @ 8,000 RPM and a massive 73 ft-lb @ at only 4,500 rpm – torque that bikes with twice the capacity make.

    The other big advantage of a turbocharged arrangement is that it will supposedly have improved emissions and fuel economy over a similarly sized 600 cc bike by as much as 50 per cent. For this reason alone, we’ll see more and more brands returning to forced induction technology as emissions regulations in Europe and California become stricter.

    We’re very excited for Suzuki this year. After years of languishing at the bottom of the Japanese pecking order, they’ve returned to MotoGP full-time and there are big rumors that an all new GSX-R1000 will debut before years end. 2015 could well herald the renaissance of Suzuki motorcycles.
