Suzuki to bring back Turbo powered bikes

Did you know that the idea of using a compressor driven by exhaust gasses to force air into an internal combustion engine to increase power output(turbo) was invented in 1909.

"Suzuki to build a production version of the Recursion concept"

Basically a turbocharger is designed to increase mass airflow into an engine where it enables the engine to produce more power without ruining any power from the engine.

“The concept made its first UK appearance at Motorcycle Live 2014, where we gathered feedback on the styling and technologies involved to help the factory with planning and development.” said Suzuki GB General Manager Paul de Lusignan.

production model is ongoing, the core will be a turbo charged 588cc parallel-twin, because of the turbo system a newly designed intercooler must be added which in exchange will require changes in the headlight design.

"Big low-rev torque"

On the October 13th Tokyo Motor Show where the bike was unveiled, Suzuki claims that uses a 588cc parallel twin with a single turbo producing 99bhp at 8,000rpm. The engine is a single-overhead-cam design for lighter and smaller dynamics compared to DOHC engines.The Intercooler is an air to air design laying underneath the rider's seat unlike Kawasaki's supercharged H2 that does not use an intercooler. Fitting an intercooler on motorcycles can be challenging but its has its own purpose, it cools the pressurized intake air and thus lowering the temperature of the charge prior to entering the engine to produces better combustion.
But whats impressive is that the torque is measured to be 74ftlb at 4,500rpm, a figure you can only get from 1,000cc superbikes.

Underneath the front of the engine is where the turbo is attached specifically to be as near as it could be to the headers to reduce turbo lags. The air filter is found beside the rider's left foot where its sucks and compresses air then sends it to the intercooler, on normal bikes where air is passed thru the radiator then cooled with water The intercooler uses air itself via large pipes covered in fins for heat reduction. The intaked air is now delivered to a pressurized box attached to the body of the engine. The silencer and catalytic converter are also placed underneath the engine, Suzuki really tried to utilize the available spaces without compromising the performance and design of the bike.

"Since the down fall of turbo-bikes in the mid-1980's,
why go back to turbos now?"

Efficiency - that is what modern turbos are all about. bigger NA type engines relies on the throttle valves, when the valves are not wide open the engine struggles therefore affects power and emission at low speed. a turbo charger equipped bike on the other hand improves the losses associated with bigger NA type engines.

With Kawasaki releasing a supercharged Ninja and with Suzuki's production version of the Recursion concept to be the first bike to bring back turbos, a new battle between Innovation, Design and Dreams are about to start in the world of motorcycles. have you chosen your side yet?
