Honda Teases Upcoming V3 Motorcycle Engine with Electric Compressor Tech

Honda has taken the wraps off its new 75-degree V3 engine, which was first teased at EICMA 2024 in Milan. This engine uses an unusual layout—two front cylinders and one rear—to blend the punch of a three-cylinder motor with the slimmer form of a twin. The result is a compact engine aimed at better aerodynamics and weight distribution. After over 1,100 hours of dyno testing, the engine is now close to production, marking a big step forward for Honda in high-performance motorcycle tech.

One of the most interesting features of this engine is its electric compressor. It’s a fresh take on boosting power, doing away with traditional turbos and superchargers. Since it doesn’t rely on exhaust gases or engine speed, the boost kicks in immediately—no lag. This gives the rider smooth, consistent torque across all rev ranges, especially at low speeds. And without needing an intercooler, the engine stays compact but still delivers strong performance.

Balancing a V3 engine can be tricky due to its uneven cylinder layout. But Honda’s engineers used their experience with bikes like the RC211V MotoGP machine to fine-tune crankshaft and piston timing. That means no need for extra balancing shafts, keeping things light and efficient. The engine also gets a unique exhaust note from its firing order—something riders are likely to notice and appreciate.

Honda has confirmed that this engine will power some of its future large-capacity motorcycles. Thanks to the electric compressor, a 750-800cc engine could perform like a 1,000cc one, with added benefits like better fuel efficiency and fewer emissions. This opens the door for new motorcycle designs that offer both performance and smarter packaging.

With this V3 engine, Honda is showing there’s still life in petrol-powered bikes. By combining electric tech with clever engineering, they’re aiming to deliver quick throttle response, smooth operation, and a strong riding experience. Now, riders and fans are waiting to see which models will get this engine and how it might shape the future of performance motorcycles.
