The MBK Booster Spirit 50cc is a legend in the world of two wheels. Many current motorcyclists started with this scooter. Its maximum speed barely reached 45kmh, but the beautiful sensations on its handlebars were… memorable.
The MBK Booster Spirit is a bestseller
A fashion phenomenon when it was launched in 2013, the MBK Booster opens the way to a new category of scooter. Its large wheels were a small revolution in the world of mopeds accustomed to finesse. Two million copies of this model left the brand’s assembly lines in Saint-Quentin in Picardy. The product’s success even benefited copiers who produced similar versions.
The pioneer of the BWS or big wheel scooter category looked great with its wide rim tires and its double globular optics. Aesthetics was not his only argument. The public loved the reliability of its 49.2 cc 2-stroke engine. Those under 16 could experience the pleasure of driving this slightly nervous motorcycle before having their A prime license.
A reliable scooter that has become a rare gem
Sold for less than 2000 euros on the second-hand market, the MBK booster 50cc is the perfect gift for a teenager lacking excitement. The height of saddle adjusted to 815 mm made it accessible to all sizes. This scooter reassures parents with its clumsy appearance. The 120/70-13 and 140/60-13 tires were like a crazy gamble for the manufacturer. Its 190mm front and rear disc brakes inspired confidence. Speed is not the strong point of this 97 kg empty model, but the 3.6 Nm of torque at 6000 rpm is more than sufficient for romantic trips!
This scooter belongs to a bygone era when 2-stroke engines were allowed. Its single-cylinder carburettor remains a vestige of the past. Unlike current injector two-wheelers, it can still be started with a kickstarter. That said, the electric starter was also functional. It remains for the driver to check the contents of the small 6.5 liter tank before setting off on a trip. The oversized wheels allow you to go off-road.
Other details to know about this 2-stroke moped
Euro 2 certified, the Booster Spirit 50 can no longer be driven in many municipalities which prohibit 2-stroke engines. However, there was a time when the post office and many companies had a large fleet of similar motorcycles. That said, it can still continue to drive in areas where emissions standards are less strict. Indeed, its single cylinder, described as “smoky”, burns gasoline and oil at the same time.
2-stroke engines have the particularity of starting at a quarter turn. They also provide immediate torque from the slightest rotation of the throttle grip. On the other hand, wear occurs more quickly than with current 4-stroke models. Finally, MBK is a French manufacturer which was responsible for assembling the Spirit Booster sold under the name Yamaha BWS on the international market.
