Japanese motorcycles moving into forced induction

While turbocharging and supercharging may be nothing new in the automotive industry, motorcycle engines are almost always naturally aspirated. But even that's beginning to change. At the Tokyo Motor Show last week, two major Japanese companies showed off new forced-induction motorbike engines.
Kawasaki rolled in with a supercharged four-cylinder motorbike engine. It offered little in the way of details, disclosing only that the turbine blades were developed in-house to withstand the heat and vibration of spooling up at motorbike speeds.
Suzuki is taking a different approach, however. Its Recursion concept bike packs a turbocharged 588cc two-cylinder engine with a turbocharger and intercooler. The compact package churns out just under 100 horsepower and 74 pound-feet of torque, packaged into a motorbike that weighs just 384 pounds dry.

Suzuki introduces reborn Katana motorcycle

At the Cologne INTERMOT motorcycle show, Suzuki has shown its all-new Katana bike. The model brings back the classic, sword-referencing Katana name, which the manufacturer first used in 1980 — that bike, the GSX1100S Katana, was also unveiled in Cologne all those years ago. The bike utilizes a modified version of the GSX-R1000 engine in a lightweight, twin-spar aluminum frame. The engine's 150 peak horsepower comes at 10,000 rpm; the bike weighs 474 pounds. There's a fully digital gauge cluster, complete with the classic Katana logo. The bike's styling is quite dynamic, as if it were in fact sliced into completion using a Japanese sword. It is highly reminiscent of the Katana 3.0 concept Suzuki showed last year at EICMA — consider the new Katana a road-going version of the concept bike. The stacked headlight has LED running lights, and the taillight, fitted in the angular tail, also comprises LEDs. The plate in turn is fixed on a swingarm extension, as near the rear tire as possible. There are fully adjustable 43mm USD front forks and an adjustable rear shock from KYB, Brembo brakes from the GSX-R1000 and Bosch ABS. A three-mode traction control system is included, but it can also be excluded via switching it off. The system monitors wheel speeds, throttle and crank position, adjusting timing and air delivery to reduce engine output when it notices wheelspin. The related GSX-R1000 and R1000R models are also updated; the latter gets an adjustable swingarm pivot and new stainless steel braided brake hoses. The R1000R's bi-directional quickshifter and auto-blipper are now standard on the R1000, enabling smoother gearshifts. The Katana and the updated GSX-R1000 and GSX-R1000R reach dealers in spring 2019.

Toyota and Suzuki are looking at an R&D partnership because they admit they're behind

The Chairman of Suzuki Motor Corporation, Osamu Suzuki, and the President of Toyota, Akio Toyoda, have convened at Toyota's Tokyo offices to declare plans to join hands regarding research and development. According to Toyoda, Toyota "hasn't been good at creating alliances," and its partnership with the small carmaker Daihatsu has been the most well-known collaboration so far. Perhaps the comment has a tinge of regret from Toyota and GM's NUMMI days in Fremont, especially as the statement released by Toyota says that "Toyota is conscious of the fact that it may be behind competitors in North America and Europe when it comes to the establishment of standardizations and partnership with other companies." But as different technologies advance at breakneck speed and it is difficult for companies both big and small to stay competitive, let alone ahead of the game, Toyota is accepting the need for collaboration. Toyoda referred to passenger safety, environmental issues, automated driving, and hydrogen technology, all of which are key challenges for any carmaker looking to stay relevant, and all expensive to experiment with. Spreading the cost over more vehicles should help. "We received an offer from Suzuki regarding collaboration possibilities on advanced and future technologies such as in information technology. Suzuki made a frank proposal to us, and in understanding that Toyota is facing the challenges which I had mentioned earlier, we thought that with the relationship between both companies, there is an opportunity for a business partnership to help solve such challenges. As such, we decided to explore such possibilities together," said Toyoda. In the future, Daihatsu will still be Toyota's tool in emerging markets, but now Toyota could have access to Suzuki's small-car know-how. Osamu Suzuki acknowledges that "Suzuki's current business focuses on minivehicles in Japan and India," as Suzuki withdrew from the US and Canada in 2013. A joint effort will help Suzuki remain relevant, and as a manufacturer of predominantly small vehicles it has been focusing on competitive pricing more than cutting edge technology. Related Video:
