If you have twenty minutes to spare, this video is very interesting.
220bhp from 578cc, fuel efficient and clean.

That’s interesting thanks, really hope it does go into production, though not sure how long it would last if it does come, as everything is going towards electric

Oh wow, that’s incredible, both from an engineering perspective, as well as an opportunity perspective . That would be pretty awesome by the sounds of it in a bike.
Wish they had shown what it sounded like without the exhaust being extracted. Bet it would have been pretty awesome!
Some high-level comparisons:
I’ve chosen a Ducati Panigale V4 as this seems most comparable in terms of performance and the fact it’s the bike to have at the moment.
| Spec | REV Force Engine | Ducati Panigale V4 Engine |
|---|---|---|
| Displacement (cc) | 578 (–48%) | 1103 |
| Weight | 50 kg (–25%) | 67 kg |
| Max Horsepower | 220 (+1.9%) | 216 |
| Max Torque | 176 Nm / 130 lb·ft (+45.5%) | 121 Nm / 89 lb·ft |
| Max RPM | 8000 (–40.7%) | 13,500 |
| Engine Format | Inline two-cylinder, two-stroke | V4, four-stroke |
| Cooling System | Liquid cooled | Liquid cooled |
Okay, next part of this post is speculative based on some basic info about the engines given to Copilot. A quick and dirty job. Take it with a pinch of salt. Still, interesting I think…
Copilot Assessment:
That torque boost from the REV Force engine is seriously impressive, especially paired with a much lighter chassis. Of course, it’s trading some top-end finesse for that punchy low-mid power.
Riding Dynamics Snapshot
- RevForce Engine: With its higher torque and lighter weight, you’d expect explosive low-end power and quicker acceleration, especially out of corners. The two-stroke nature means rapid throttle response but less top-end overrun. Perfect for short tracks or tight road circuits.
- Ducati Panigale V4: Thanks to the high redline and smooth V4 delivery, this engine thrives on high-speed sweepers and longer straights. It’s more refined, with broader torque distribution, making it easier to ride consistently fast—even if it’s a bit heavier.
Dyno Curve Sketch (in words)
Imagine two lines:
- RevForce’s torque curve would peak early—sharp rise up to 176 Nm around mid-rev (~5000–6000 RPM), then taper off before 8000 RPM.
- Ducati V4 would show a more gradual build in torque, maxing at 121 Nm closer to 10,000 RPM, holding a flatter line until its redline at 13,500 RPM.
- Horsepower curves intersect around the 8000 RPM mark. Above that, Ducati’s line keeps climbing, while RevForce starts fading.
It’s a classic case of punch vs poise.
Speculative Race Circuit Comparison:
How an engine feels on different types of tracks can totally transform your riding experience—like choosing between a scalpel or a broadsword. Here’s how these two engines might perform depending on the circuit style:
Tight, Technical Circuits (e.g., kart tracks, twisty road circuits)
RevForce Engine would shine here. Its lighter weight and sharp torque delivery at lower RPMs mean faster corner exits and snappier throttle response. You’d be dancing through switchbacks while the Ducati V4 might feel like it’s waiting to hit the power band.
Fast, Flowing Circuits (e.g., Mugello, Silverstone)
Here’s where the Ducati Panigale V4 stretches its legs. Long straights and high-speed sweepers give that high-revving V4 time to unleash. With its broad powerband and stability at speed, the Ducati feels planted and majestic, while the RevForce could run out of breath before the straights end.
Street Circuits or Urban Tracks (e.g., Macau, urban GP courses)
Quick throttle response and agility matter most. The RevForce’s compact build and punchy midrange would feel like riding a caffeinated wildcat—ideal for darting between tight barriers. Ducati’s refinement might be overkill in stop-and-go scenarios.
Mixed-Style Tracks (e.g., NĂĽrburgring, Isle of Man TT)
This is the proving ground for versatility. The Ducati would likely offer more composure over longer stints and varied conditions, while the RevForce could feel thrilling but demanding to manage over extended rides.
