Superchargers have always been popular when it comes to cars but when it comes to motorcycles, they haven't been in vogue for long. It all started when Kawasaki launched the ballistic Ninja H2. And since then, we've heard a lot of rumours about quite a few manufacturers looking into the supercharger tech... mostly patents. In the latest news, Honda has just renewed their supercharged V-twin patent and that... should mean something's coming.



Supercharging, along with turbocharging, is a wide-spread method used in cars to help wring more power out of smaller, more fuel-efficient engines. In motorcycles, there are just 2 examples; both from Kawasaki. We are talking about the Ninja H2 and more recent Z H2. Both the motorcycles feature a supercharged 999cc inline-4 engine.

In the case of other manufacturers, we've only had rumours. Rumours of Suzuki considering a supercharged engine for the next-gen Hayabusa and BMW exploring electric superchargers. Nothing concrete. Honda's supercharger patents go way back but with the passage of time and no real implication so far, they were buried under the pile.

Recently, Honda has updated its patent for a supercharged v-twin engine. Considering that Kawasaki's inline-4 is the only forced-induction mill out there, a supercharged V-twin ought to make things interesting. The patent filing gives away concrete cues that the design of the engine is all but complete and it's not like Honda has any shortage of chassis components lying around... so what are they waiting for?

Well firstly, as we can see in the picture, the motorcycle depicted in the filing does not resemble any current model in their stable. It looks like a mix of a modern-design streetfighter and their own Neo-Sports Cafe. That can only mean that this motorcycle may not be a part of any existing line of products but a new product altogether.

The star of the show is, of course, the supercharged, direct-injection V-twin. The document describes an “internal combustion engine with a supercharger for a saddle-ride type vehicle wherein the internal combustion engine is a V-type internal combustion engine including a front bank and a rear bank, wherein one of the front bank and the rear bank is provided with the TBW throttle device.”



Sadly, the patent was filed in 2017 and it has remained a patent since. Fortunately, it was published (updated) January 2020 and that might mean that Honda may have something planned. Of course, 'may' is the keyword.
