The MBK Stunt was MBK’s version of the Yamaha Slider, a plain and inexpensive 50 cc scooter built in France. It was the cheapest model Yamaha offered while it was on sale, and its simplicity made it a favourite of young riders.

History of the MBK Stunt
One scooter, two names
The Yamaha Slider was built in France and sold in several countries; at home MBK called it the MBK Stunt. Production ran from 1999 to 2004, and so many parts carried MBK’s name that French registration papers listed MBK as the maker. Apart from differently painted body panels and stickers, and the name on the side, the Slider and the Stunt were the same machine, and the Stunt was sold directly by MBK.
Simple engineering
The engine was a 49 cm³ air-cooled two-stroke of 2.5 kW (3.4 hp), or 2.7 kW in German figures, with a single disc brake at the front and a drum at the rear. It started on the button or on the kick, and had a rarity for scooters of its generation: a choke lever on the handlebar. The tank held 6.5 litres, and two-stroke oil lived in a separate 1.1-litre tank, metered into the fuel at 1:72.
Practical but plain
There was no helmet compartment under the seat, although a luggage rack and a top case could be fitted. The exhaust had a catalytic converter that clogged easily, especially when the scooter was restricted to 25 km/h for young riders, and many owners replaced it with a sport pipe. As the cheapest scooter in Yamaha’s range, the Stunt was deliberately simple in design and construction. In 2008 it was the subject of a recall campaign because of a defect in the front brake hose.

- Mixed brakes: a single front disc and a rear drum, light and easy to maintain.
- Two ways to start: electric starter and kick starter.
- Handlebar choke: unusual for scooters of its generation.
