MALOSSI Cylinder Kit - Ø47mm for KYMCO KXR 50, MAXXER 50, MXU 50 2004-2007

MALOSSI offers this cylinder kit for KYMCO KXR 50, MAXXER 50, MXU 50 2004-2007. The cylinder kit groups a cylinder and the parts to fit it (piston, rings, gaskets depending on the kit: see contents). “Big bore” kits increase the bore and therefore the displacement: the engine gains torque and power.

Why buy a cylinder kit?

The benefits:

• A cylinder and its matched piston: perfect fitting clearance.
• One order to rebuild the top end.
• Big bore versions give more torque and power (check the rules if you race).

Why choose MALOSSI?

Malossi began in 1930 in Bologna as Armando Malossi’s bicycle and motorcycle workshop. Now based in Calderara di Reno, just outside Bologna, the brand develops its scooter and moped performance parts in a 12,000 m² plant with robotic production cells, test rooms and laboratories.

When should you replace the cylinder on your KYMCO MXU 50?

Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.

No manufacturer hour figure for this model. Cross-Mania guideline: compression check every 30 h in hard use and every 60 h for leisure.
