Cylinder Kit DR 50cc cast iron Yamaha BW's / Slider

Cylinder DR Evolution 50cc Minarelli vertical

Are you looking for an affordable, robust cylinder suitable for everyday use that also gives you more power? Then the DR Evolution 50cc cylinder kit is just right for you.

DR Evolution cylinder design

The cylinder has 5 transfer ports and is supplied with a 2-ring piston. The performance of the kit is similar to the TopPerformances cylinders, 5 to 7 hp are realistic, depending on what exhaust you use. All in all, a powerful cylinder for little money. The kit can easily be run with the original carburetor (adjust the jet and spark plug ) and will last a good 20,000 km if it has been run in properly. Nevertheless, we recommend using a 17.5mm carburetor and a performance exhaust.

Attention: Supplied without cylinder head, simply reuse the original head.
