Not long ago, the only “American” way to get more power from an engine was to make it bigger and while things haven’t completely changed, we do witness technological progress being applied on engines such as this V4 powering the latest Motus. It features Gasoline Direct Injection (GDI) instead of upstream injection and what the first system does is inject gasoline straight into the combustion chamber right after the intake process is complete, significantly improving the engine’s blows, which translates into more performance.

And speaking of performance, this engine is no stranger to it as it is designed by Michigan-based Katech, which also happens to supply the engines for the Pratt and Miller Corvettes. That is why you won’t have troubles spotting plenty of similarities between those and the Motus engine if curiosity strikes you.

A recent Cycle World article by Kevin Cameron speaks about the benefits of GDI, while Brian Case told The Kneeslider this is “the first V4 made in America for a production vehicle, the first gDI production motorcycle engine, and even the first gDI V4 for that matter.”

Configured as a 1650cc, V4 with 2 valves per cylinder, the Made in America powerplant makes 140hp, but we still can’t help but notice how the performance upgrade is still related to gas, meaning that this mill is after all faithful to its origins.

Why do I want a chain drive sport tourer - I don’t think so. Maybe if I was racing or into serious sport bikes but not on a touring bike. I doubt they will have cruise control, heated seats and grips, radio, and adjustable windscreen. Don’t need 140hp on a sport touring bike. This sounds like the nonsense Honda came out with on the new VFR. They are calling that bike a sport touring bike also. I guess if they put some side cases on it and maybe heated grips it instantly becomes a sport touring bike. BMW is the only company that makes a true Sport Touring bike.

Another disappointing chapter in the American motorcycle technology book. While the Japanese manufacturers can make 600 cc inline 4’s with 140hp or close to it, this engine harkens back to the time of the covered wagon with two valves per cylinder and a displacement larger than some cars! Direct injection is great! But the rest of that engine is hardly worth the space on the internet. I wish a company like this would really utilize the technology available to do something innovative. The US has one good hope for a desirable technologically innovative motorcycle and that comes from the Motoczysz camp.
