Having previewed a prototype V3 engine with an electrical compressor at the 2024 EICMA motorcycle show in Milan, Honda’s vision of internal combustion engined (ICE) motorcycles has become even clearer after the Japanese giant showcased a complete bike at last month’s big international shows.
Unveiled at EICMA 2025 and brought over to our own Motorcycle Live, fuller information regarding the ‘V3R E-Compressor Prototype’ is starting to emerge.
When we wrote about the 75° V3 last year, we speculated on an engine with a capacity of between 700 and 900cc. Honda have now confirmed the prototype clocks in at 900cc but should pack a punch equivalent to a naturally aspirated 1200cc machine. Taking something like Triumph’s Speed Triple 1200 as a benchmark, that means around 180bhp and plenty of low down torque from the blown motor.
As we speculated 12 months ago, the prototype utilises an electrically powered compressor, which would be a first in the motorbike world. Similar technology is also starting to break through in the car world and allows smaller engines to be more efficient.
It compresses air and forces it into the induction, allowing engines to release more performance than a naturally aspirated alternative. By being electronically controlled, as opposed to mechanically controlled like a traditional supercharger, engineers should be able to have greater control of the E-compressor’s characteristics, while it should also be smaller and more responsive than a regular supercharger or turbo charger.
Honda are developing the technology as part of its ‘2030 Vision’, as it works to develop safer and more environmentally friendly products without losing the fun factor. By adding a compressor to a 900cc internal combustion engine, the V3R should not only make the power of a 33% larger engine, it will also most likely have improved fuel economy and lower emissions levels than a naturally aspirated alternative.
Where last year’s engine prototype was presented in a simple trellis style frame, the V3R displayed at Motorcycle Live appeared as a complete motorcycle which looks close to production ready.
Beneath the distortion style graphics used to camouflage prototype designs, the rolling chassis looks fairly conventional. The distinctive asymmetric airbox design is the main giveaway as to what may lie underneath the skin, with the large scoop on the rider’s right hand side being where the air is forced into the compressor. Another small, although significant, touch is the new tank badge.
Honda call it the ‘Flagship Wing’ and comes as part of a corporate identity overhaul which sees some new logos for different products, with the ‘Flagship Wing’ applied to ‘Fun’ ICE powered machines and a new script used for electric vehicles, which has debuted on the 2025 WN7.
Although there’s no word on when, or indeed if, the V3R will make production, we fully expect to see this technology in our showrooms fairly soon. This year saw the introduction of the WN7, the company’s first full-sized EV motorcycle, a year after it was introduced as a concept during the winter shows, and it would be no surprise to see a production motorcycle based on the V3R on our roads in the next 12-18 months.
