NK102.53 - Naraku Cylinder Kit V.2 For Derbi GPR 50 Nude 2004-2005

Features: The long proven 70cc Naraku cylinder kit is now also available in a V.2 version for EBE / EBS engines. Naraku offers this kit exclusively with a 70cc cylinder head precisely 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 are deliberately not in the foreground with this sports cylinder. This Naraku cylinder kit is recommended for both stock exhaust systems and sport exhaust systems. If the original carburettor remains installed, it is highly advisable to increase the carburettor jetting by about 7-10% (guideline). We recommend using a sports carburettor (19mm).
