1000cc Street-Legal Quad: “Feels like a Formula 2 car with a motorcycle handlebar – positively crazy…”
The BMW M 1000 R is the company’s flagship “hyper-naked,” featuring a 207-bhp ShiftCam engine from the S 1000 RR homologation superbike — a motor that’s neither detuned nor remapped before going into this highly sophisticated flat-bar monster. The “MR” makes 44 more bhp than than BMW’s S 1000 R “Single R” naked bike.
The “MR” is surprisingly easy to live with at sane speeds, but the story changes once you get into the sweet spot of the WSBK-bred engine:
“At 9,000 rpm the M 1000 R morphs into an entirely different beast. It revs so freely that it feels like the engine is frictionless. A wall of frantic air grabs feverishly at your leathers, you bend your torso into some kind of defensive tuck… And the speed just builds relentlessly.” –Motorcyclist
Two hundred and seven ponies is a lot to put down through a single 200/55-17 rear tire, but there’s a company in Germany that transforms this two-wheeled super naked into a four-wheeled monster…while retaining a handlebar.
Meet EXEET GmbH, founded in 2012 by veteran quad racer Sebastian Jornitz, who spent years designing and building his own racing quads (and running his own dealership) before starting a company to build street-legal motorcycle-based “hyperquads” for customers. Bases include the BMW S 1000 RR, Kawasaki Z H2, Ducati Streetfighter, and others.
We spoke with EXEET managing director Thorsten Arenz about the “MR Competition” model you see here, which combines the M 1000 R engine and electronics suite with a proprietary chassis and suspension setup. In this case, the inspiration came from modern GT and prototype race cars.
“The design idea in one sentence was: ‘Superbike heart in a vehicle that visually feels more like a small prototype race car — clean, technical, without fake drama.'”
With Sebastian’s racing experience as a key driver, EXEET doesn’t build novelty show machines — their quads are built to perform on the street and track. The wide-track chassis is fabricated in-house, sporting double-wishbone / pushrod front suspension and a dedicated rear axle with Öhlins shocks tuned just for this vehicle and its rider.
EXEET’s own performance braking system includes internally ventilated discs, and the front and rear carrier structures are also designed in-house. The bodywork is custom, including carbon fiber panels to keep down the weight, and the BMW M electronics package is fully integrated to work with four wheels instead of two.
As you can imagine, the thrust and mechanical grip are simply extraordinary.
“It feels like a Formula 2 car with a motorcycle handlebar – positively crazy… On the road it’s extremely precise: sharp turn-in, lots of feedback, brutal but controllable braking. On track it becomes a real edge-of-your-helmet experience — very late braking points, high corner speeds, and superbike-level acceleration out of the turn, but with much more stability.”
The matte silver paint of this model — and the way it rockets out of corners — earned it the in-house nickname “Silver Arrow.” Germany is notoriously strict in terms of vehicle regulation, but the EXEET MR Competition is fully registered for road use in the country…you only need a regular drivers license to operate it!
While we’re partial to two wheels here at BikeBound, this is one hyperbike-based four-wheeler we’d love to ride. Below is our full in-depth interview with Thorsten Arenz of EXEET, including many more photos and technical details.
EXEET MR Competition Hyperquad: Director Interview
• Please tell us a bit about yourself, your history with motorcycles, and your workshop.
My name is Thorsten Arenz, I’m one of the managing directors of EXEET GmbH in Euskirchen, Germany, and I’ve been with the company since 2020. My professional background is actually in the car and commercial vehicle industry — I did a commercial apprenticeship, held various roles in the automotive world, and most recently worked as a branch manager at MAN. So I mainly bring topics like organisation, quality, structured processes, and customer care into EXEET.
EXEET itself was founded in 2012 by Sebastian Jornitz. Sebastian used to race quads successfully, and even back then he was designing and building his own race machines, because what was available on the market simply wasn’t good enough for what he wanted to do. In parallel he ran a very successful quad dealership, including Polaris, where he was awarded “Newcomer of the Year.”
Today Sebastian is the technical head and chief designer behind our vehicles, while I focus more on the commercial side and structure. In our workshop in Euskirchen we build street-legal hyperquads that combine modern superbike performance with a completely proprietary chassis and suspension concept — always as one-off builds, planned very personally together with the customer.
• What’s the make, model, and year of the donor bike?
This EXEET MR Competition is based on a current-model BMW M 1000 R. We only use brand-new motorcycles as donor bikes — never used ones.
• Why was this bike built?
This silver MR Competition with matte metallic paint and carbon parts is a mix of a customer project and a company show bike. On the one hand, we wanted a machine that clearly shows what is technically and visually possible on the MR platform. On the other hand, we had a customer who wanted exactly that: uncompromising performance, lots of exposed carbon, but still a very clean, technical look rather than a loud show build.
• What was the design concept and what influenced the build?
The design idea in one sentence was: “Superbike heart in a vehicle that visually feels more like a small prototype race car – clean, technical, without fake drama.”
We chose matte silver metallic as the main colour because it lets the proportions of the vehicle speak without shouting for attention. The carbon parts are placed very deliberately around the front, sides and rear, exactly where the technical action is: suspension, brakes, air flow.
Visually, the build is strongly influenced by modern GT and prototype race cars: clear lines, defined edges, no unnecessary gimmicks — a design that puts engineering and function front and centre.
• What custom work was done to the bike?
From the M 1000 R we mainly keep the engine, electronics, and some peripheral systems — the overall vehicle concept is completely rebuilt as a hyperquad. Key work includes:
- Development and fabrication of a complete EXEET quad chassis with a wide track
- A double-wishbone / pushrod front suspension with Öhlins shocks, tuned specifically for this vehicle
- A dedicated rear axle concept with custom mounts
- Our EXEET Performance brake system with large, internally ventilated discs and a bespoke brake balance
- In-house-designed front and rear frame / carrier structures
- Custom bodywork and carbon panels, matched to the quad chassis and new proportions
- Adapting steering, seating position, footrests and controls to the new layout
- Full integration of the BMW M electronics package (riding modes, traction control, suspension control, TFT, etc.) into the new vehicle concept
So in the end, it’s less a “conversion” and more a new vehicle that uses the M 1000 R as its technical heart.
• Does the bike have a nickname?
Officially the bike is called “EXEET MR Competition”. Inside the workshop, it very quickly picked up the nickname “Silver Arrow” — because of the matte silver paint, the carbon and the way it fires out of corners.
• Any idea of horsepower, weight, and/or performance numbers?
Yes – we’re in the range of the M 1000 R figures, adapted to our concept:
- Engine: 999 cc inline-four
- Power: about 210 hp
- Torque: roughly 116 Nm
- Ready-to-ride weight: around 255 kg (depending on spec)
- 0–100 km/h: about 2.7–2.8 seconds
- Top speed: around 230 km/h
The MR Competition is registered in Germany as a new vehicle for two people, and you can legally drive it here with a car licence (class B). The whole setup is tuned so that the vehicle really sticks to the road — lots of mechanical grip, supported by the M electronics.
• Can you tell us what it’s like to ride this bike?
The most accurate description we’ve found is: “It feels like a Formula 2 car with a motorcycle handlebar – positively crazy.”
You sit in the vehicle rather than on top of it, with a low seating position and a very wide track. The pushrod front end and that width give you a huge amount of confidence, and the MR literally feels like it’s glued to the road.
At the same time you have the full BMW M electronics — riding modes, traction control, suspension control and so on — making the huge power surprisingly usable.
On the road it’s extremely precise: sharp turn-in, lots of feedback, brutal but controllable braking. On track it becomes a real edge-of-your-helmet experience — very late braking points, high corner speeds, and superbike-level acceleration out of the turn, but with much more stability.
• Was there anything done during this build that you are particularly proud of?
Yes, two things stand out for us:
1. The full integration of the BMW M electronics into our quad platform.
After such a deep transformation, everything still works as if the bike left the factory like this – riding modes, traction control, suspension control, TFT, rider aids. There’s a lot of development work hidden behind that “it just works” feeling.
2. The overall balance of the Competition spec.
The MR Competition could easily have become a pure showpiece. Instead, it’s a very serious performance tool that happens to look wild. It’s eye-catching, but everything on it makes technical sense — and the important part: it actually gets ridden hard, not just parked as garage art.
• Is there anyone you’d like to thank?
Absolutely.
- First of all our EXEET team, who put so much handwork, experience and attention to detail into these builds.
- Then Sebastian Jornitz, as the designer and technical brain behind the concept.
- A very special thank you goes to the BMW Niederlassung Bonn (BMW dealership in Bonn), and especially to Oliver Banisch — without his support and cooperation on the donor bike, this specific vehicle simply wouldn’t exist.
- We’d also like to thank our partners in suspension, brakes and electronics, and of course the customer who had the courage to build something this extreme with us — and actually uses it properly on the road and on track.

I have ridden versions of concepts like this and they are very tireing to ride compared to the two wheeled version, lack of leaning in the corners takes a big toll on the body and I believe not as good of performance.
