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.

2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo

The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff.  Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).
