Moped Engine DBR 4P

Item description:

The DBR 4 stud engine with forced air cooling is available in three versions, each designed to meet different performance needs in the motorcycle mechanics field.

• DBR 4p sport: engine with 70cc cast iron thermal group, 6 transfer ports, and elliptical exhaust.
• DBR 4p competition: engine with 70cc aluminium thermal group, 6 transfer ports, and exhaust with booster ports.
• DBR 4p extreme: engine with 70cc aluminium thermal group, 5 transfer ports, and exhaust with crossbar.
• Internal rotor ignition with variable advance.
• Flat valve carburettors of 24mm, 26mm, and 28mm, depending on the version.

The materials used for the engine’s construction ensure sturdiness and reliability. The cast iron or aluminium thermal group is designed to withstand high stresses, while the ignition and carburettor are optimised for superior performance.

The engine is compatible with various transmission systems and can be supplied assembled or for assembly. The use of a reinforced DBR skid plate is recommended to maximise performance.
