Veloce Motorcycles unveils a 1000cc X8 two-stroke café racer!
Built by Oxfordshire-based Veloce Motorcycles, the Aperion is a 1000cc, eight-cylinder, two-stroke naked bike — or perhaps more accurately, an engineering provocation with lights, wheels, and a number plate. Veloce claims 280 horsepower at 12,000 rpm from its in-house X8 two-stroke engine, with production limited to just 24 examples and commissions available for 2027.
Truly this eight-cylinder two-stroke seems like it was sketched out during a late-night argument over whether the maddest ideas from the two-stroke era could be resurrected with modern engineering. For anyone who grew up on the scent of Castrol, the shriek of 500cc GP smokers, or the manic charm of 125cc and 250cc two-stroke sport bikes, that alone is enough to raise the pulse. But the deeper you look into the Aperion, the stranger and more fascinating it becomes.
The Return of the Roadgoing Two-Stroke?
High-performance roadgoing two-strokes have been all but legislated out of existence. The likes of the Suzuki RGV250, Aprilia RS250, Yamaha TZR250, and Honda NSR250R remain legends, but they belong to another age — a time when light weight, razor-edged powerbands, and blue smoke were accepted parts of the sportbike experience.
In recent years, a few boutique manufacturers have dared to revive the format. Langen Motorcycles, also from the UK, brought us the Langen Two Stroke: a featherweight, street-legal 250cc V-twin with around 75 hp and a level of craftsmanship more akin to a watchmaker than a mass-production motorcycle factory.
Veloce, however, has gone in a very different direction. Where the Langen Two Stroke is delicate, jewel-like, and minimalist, the Aperion is baroque and brutal — an eight-cylinder two-stroke built around an engine that sounds like the fever dream of a Grand Prix mechanic.
The X8 Engine
The heart of the Aperion is Veloce’s 1000cc X8 two-stroke engine: eight cylinders arranged in an X configuration, producing a claimed 280 hp at 12,000 rpm. Veloce lists the powertrain weight at 105 kg, with the engine, chassis, and transmission combined into one load-bearing unit.
According to reports, the engine uses eight Rotax / Aprilia RS125-style cylinders with forged pistons, arranged around two separate V4-style crankcase assemblies and a central transmission casing. Each bank is reportedly machined from billet, with paired crankshafts geared to a common jackshaft, which then drives the custom clutch and gearbox.
In other words, this is not simply a pair of two-stroke fours bolted together. It is an attempt to create a compact, balanced, eight-cylinder two-stroke power unit in a motorcycle package — and Veloce says the X-layout helps keep the machine narrow.
The configuration is also said to have a major balancing advantage. Diagonally opposed pistons fire together, allowing the opposing forces inside the engine to cancel one another. Veloce says combustive, inertial, and rotational forces are naturally balanced within the design.
For a two-stroke, the X configuration also opens up packaging possibilities that would be difficult in a conventional four-stroke. With no traditional valve train or wet-sump lubrication system to accommodate, the cylinders can be arranged in ways that would be far more problematic with a four-stroke engine.
Carbs, Premix, and Eight-Cable Throttle Glory
In an era of ride-by-wire throttles, IMUs, Euro emissions maps, and invisible electronic intervention, the Aperion’s induction system sounds gloriously mechanical.
MCN reports that the bike runs four pairs of 24mm Dell’Orto carburetors and premixed petrol / two-stroke oil. Better still, the throttle is said to use an eight-cable spiral twistgrip arrangement — the sort of detail that makes the Aperion feel less like a conventional production bike and more like a moving sculpture dedicated to internal combustion.
The claimed 280 hp output equates to 35 hp per 125cc cylinder, a figure that makes sense in the context of tuned small-bore two-stroke performance. Still, multiplying that by eight creates something very different from the traditional lightweight stroker experience.
This is not a 250cc scalpel. This is a liter-class two-stroke with superbike power, exotic engineering, and a power delivery that we can only imagine will be unlike anything else on the road.
The Eight-Pipe Problem
Of course, any serious two-stroke lives or dies by its exhaust.
Expansion chambers are not simply pipes; they are part of the engine’s breathing system. Their length, volume, cones, and internal geometry are critical to scavenging and power production. Getting them right on a twin can be challenging. Packaging four on a 500cc GP bike was an art form. Packaging eight on a modern road motorcycle borders on the absurd.
This is where Veloce has turned to modern manufacturing. The Aperion uses a laser-sintered, all-alloy resonance exhaust system — essentially allowing the expansion chambers to be designed in CAD and produced in forms that would be extremely difficult, if not impossible, to fabricate using traditional cut-and-weld methods.
The result is one of the Aperion’s most striking visual features: a complex nest of expansion chambers wrapped tightly around the engine and chassis, turning the motorcycle’s mechanical function into its defining aesthetic.
It is hard to imagine a better use case for metal 3D printing in motorcycle design. Rather than using the technology for decoration or novelty, Veloce appears to be using it to solve one of the oldest and most difficult two-stroke packaging problems.
Engine as Chassis
The Aperion’s engine is not merely housed in the frame. It is the frame.
Veloce says the chassis, engine, and transmission are combined into a single unit for exceptional stiffness, with welded steel-tube trellis-style subframes front and rear. A large aluminum single-sided swingarm mounts directly to the cases, and the rear suspension uses Veloce’s own pullrod-actuated coilover damper mounted low and forward beneath the engine.
That underslung shock location is said to aid both cooling and geometry, while the overall design keeps mass centralized. Veloce also emphasizes the Aperion’s wheelbase and low polar moment, suggesting the bike is meant to offer stability and agility rather than simply serving as a dyno-sheet monster.
The clutch is hydraulic and built into the six-speed wide-ratio gearbox mainshaft, a detail that further underscores just how unconventional this machine is.
Naturally, many of the surrounding components are more familiar: inverted forks, modern brakes, road wheels, and sport-naked ergonomics. But the core architecture — X8 two-stroke engine, integrated chassis, 3D-printed expansion chambers, and underslung pullrod suspension — is anything but ordinary.
Who is Veloce Motorcycles?
Veloce Motorcycles is the trading name of Veloce Automotive Ltd, a private company based in Oxfordshire, England. The company says its powertrains and motorcycles are developed at its own engine cell and test circuit in Carmarthenshire, Wales.
It is a new name, but its ambitions are anything but modest. Veloce says its motorcycles are designed around high power per displacement, low weight, minimal polar moment, and a visceral riding experience — the sort of philosophy that feels increasingly rare in an era of platform sharing, emissions constraints, and software-defined performance.
The Aperion is not Veloce’s only planned model. The company is also developing the Ethereal, a 500cc, four-cylinder two-stroke machine with a claimed 145 hp at 12,000 rpm. The Ethereal uses an L4 cylinder arrangement, laser-sintered resonance exhausts, an underseat radiator system, and a novel transmission layout intended to improve mass centralization and rear-suspension geometry.
If the Aperion is the halo bike — the wild, eight-cylinder flagship — the Ethereal appears to be the slightly more attainable lightweight two-stroke weapon. “Attainable,” of course, is relative.
Production, Price, and Road Use
Veloce says Aperion commissions are available for 2027, with production limited to 24 units. The company also says the bikes will be MSVA compliant for UK road use.
MCN reports a price of £78,000, which places the Aperion deep into exotic collector-bike territory. That is not surprising. This is a tiny-volume, startup-built, custom-engineered motorcycle with an engine architecture no major manufacturer would attempt in the current market.
It is important to note that the Bike Shed display bike shown to the public was reportedly a non-runner, though MCN reports that Veloce has an operational test bike at its R&D facility in Carmarthenshire. As with any ambitious startup motorcycle project, the real proof will come when running bikes are tested, delivered, and ridden in the real world.
Still, even as a statement of intent, the Aperion is extraordinary.

Does the World Need a 1000cc Two-Stroke?
In our opinion, yes. Not because the world needs a practical 280-hp two-stroke naked bike. It very clearly does not. And not because the Aperion is likely to become a common sight outside cafés, track days, or Sunday meets. With 24 units planned and a reported price approaching six figures, it will remain a rare beast.
But motorcycles have always been about more than practicality. They are about emotion, engineering, noise, smell, danger, beauty, and the stubborn refusal to accept that the most efficient solution is always the most interesting one.
The Veloce Aperion is outrageous. It is also fascinating. In a market increasingly defined by electronics, emissions, and incremental refinement, here is a British startup building an eight-cylinder, 1000cc two-stroke with carburetors, premix, laser-sintered expansion chambers, and a chassis wrapped around the engine like a sculpture.
Whether it becomes a fully realized production motorcycle, a collector’s oddity, or the first chapter in a new boutique British performance brand, the Aperion is already one of the most intriguing two-wheeled machines of the decade. Long live the mad ones.
