TL;DR: The first-generation MBK Stunt Naked found in Dunkirk is in exceptional stock condition after 22 years — Maxiscoot snaps it up to transform it in a fully filmed build project, covering teardown, paintwork and a soft 70cc engine configuration.
🛵 A Stock 2002 MBK Stunt Naked Found Intact
The MBK Stunt Naked is one of the most iconic 50cc scooters of the 2000s generation: clean bodywork, exposed tubular frame and an air-cooled vertical Minarelli engine — it introduced thousands of young riders to two-wheel mechanics. Finding one in stock condition after more than two decades is almost a miracle, given how many of these machines have been modified, dropped and badly repaired over the years.
That’s exactly what the Maxiscoot team tracked down in Dunkirk: a first-generation example that Nico, one of the team members, rode in his youth. Period paintwork with no visible touch-ups, original plastics, engine never opened — this 2002 Stunt Naked ticks every box of a truly preserved example. The trip up to northern France was absolutely worth it.
🔍 Walkaround: What the Inspection Reveals
Before any build project, a thorough inspection is essential. On this MBK Stunt, the first look is reassuring: the frame shows no signs of impact, the welds are intact and the original tyres still hold air — which, on a two-wheeler of this age, speaks to genuinely good storage conditions. The analogue dashboard works, the cables aren’t cracked and the brake levers respond properly.
On the engine side, the air-cooled vertical Minarelli block is the reference platform for entry-level scooter builds. Its straightforward architecture — side-mounted carburettor, variator accessible without complex disassembly, split crankcase — makes it an ideal base for anyone wanting to develop their mechanical skills while achieving measurable performance gains. The cylinder head and barrel still need checking, but there are no external signs of overheating or old oil leaks.
The first road test confirms what the eye had already suggested: the engine runs smoothly, the variator-belt transmission operates without jerks and the braking — modest by nature on a period 50cc — is consistent. This 2002 Stunt Naked rides like a scooter that just came out of a well-kept garage.
🎬 Today’s Video: Watch the Pickup Live
Maxiscoot filmed everything, from the drive to Dunkirk to the first start-up in the yard: the road trip atmosphere, discovering the scooter at its owner’s place, the detailed inspection and the first laps. It’s exactly the kind of content that reminds you why you fall in love with a well-preserved machine.
The video also lays the groundwork for the project ahead: you can catch the first thoughts on the engine configuration, discussions about aesthetic choices and a teaser of the partner involved in the build. Nothing is set in stone yet — and that’s precisely why your comments matter.
⚙️ The Build Project: Soft 70cc, Paint and Much More
The announced roadmap centres on a so-called “soft” build: the goal isn’t to push the engine to its limits, but to achieve a coherent performance gain that’s reliable for everyday use and compliant with current regulations for the intended purpose. On a vertical Minarelli, going to 70cc typically means a new matching cylinder-piston kit, a reworked cylinder head and a larger-bore carburettor to properly feed the increased displacement.
The aesthetic side is just as eagerly awaited. Repainting a Stunt Naked means choosing between staying true to the period spirit or taking a decisively modern direction — and that’s exactly the question Maxiscoot is putting to its community. The full plastic teardown, planned from the next episodes, will also allow a structural check under the covers and identify any wear parts to sort before the final recommission.
A Maxiscoot partner has been involved in the project from the start. Their role hasn’t been revealed in detail yet, but their expertise should guide the technical choices and ensure consistency across the selected parts. Upcoming episodes will gradually lift the lid on that.
💬 Your Say: What Setup Do You Want on This Stunt?
This project is designed as an open collaboration with the Maxiscoot community. The question posted in the comments under the video is straightforward: what configuration do you want to see on this MBK Stunt Naked? Soft 70cc as announced, a more aggressive build, a colour choice for the paint, priority on looks or performance — every piece of feedback is taken into account when making decisions going forward.
Dropping a comment, hitting the thumbs up or sharing the video is also the best way to encourage the team to keep up this publishing pace and document every step with the same level of detail. Subscribe to the Maxiscoot YouTube channel so you don’t miss a single episode of the project.
❓ FAQ
What is an MBK Stunt Naked?
The MBK Stunt Naked is a 50cc scooter with an air-cooled vertical Minarelli engine, sold from 2002 onwards. Its defining feature is its exposed tubular frame — hence the name “Naked” — which gives it a sportier, more stripped-back silhouette than the fully faired scooters of the same era.
Why is the vertical Minarelli engine so popular for builds?
The vertical Minarelli engine is valued for performance builds because its architecture is simple, well-documented and benefits from an enormous parts catalogue. 70cc cylinders, carburettors, variators and exhausts are available in countless configurations, making it possible to tailor the build precisely to the intended use — from a smoother power delivery right through to all-out performance.
What is a soft 70cc build on a 50cc scooter?
A soft 70cc build means replacing the stock cylinder-piston with a 70cc “mild porting” kit, without aggressively reworking the cylinder head or exhaust. You gain torque and mid-range pull without sacrificing reliability or everyday rideability. It’s the recommended starting point for anyone new to performance mechanics.
Is a 2002 MBK Stunt Naked hard to find in good condition?
Yes, finding a first-generation MBK Stunt Naked that’s fully stock and in good condition has become genuinely rare. Most examples have been modified, dropped or repaired over the years. A scooter this well-preserved after 22 years is an ideal project base and a real collector’s piece for fans of the 2000s generation.
Where can I find parts for an MBK Stunt Naked?
Maxiscoot stocks a wide selection of replacement and performance parts compatible with the MBK Stunt Naked, whether you need stock wear parts or build references for the vertical Minarelli engine. The dedicated category brings together all available references for this specific model.
