Kit de cylindre 70cc avec culasses - Piaggio & Derbi D50B (Euro 3)

Cylinder Kit V.2 70cc incl. cylinder head for Piaggio / Derbi D50B Euro3

• The long proven 70cc Naraku cylinder kit is now also available in a V.2 version for D50B0 engines built up to 2018 (Euro3)
• The mould was adapted to the original D50B0 cylinder
• The cylinder is painted in the factory cylinder silver colour and therefore hardly distinguishable from the original
• Naraku offers this kit exclusively with a 70cc cylinder head exactly matched to the cylinder
• The resulting compression ratio makes the kit a daily driver with rich torque and excellent acceleration values
• High revs and associated noise levels were deliberately not in the foreground with this sports cylinder
• The cylinder head thread matches temperature sensors built up to 2018 with Euro3 emissions standard
• Practically, the cylinder head also fits Euro4 models
• However, for these Euro4 vehicles, the thread adapter NK103.78 must be used in addition
• This Naraku cylinder kit is recommended for both standard and sports exhaust systems
• If the original carburettor remains installed, it is highly advisable to increase the carburettor jetting by about 7-10% (guideline)
• We recommend to use a sports carburettor (19mm)
