The Naraku NK103.74 cylinder and piston kit includes a 70 cc V.2 cylinder and matching cylinder head for D50B Euro4 engines manufactured from 2018 onward. The cylinder has a shape adapted to the original and an anthracite finish. Its compression makes it suitable for everyday riding, with an emphasis on torque and acceleration.
The cylinder head thread is compatible with temperature sensors manufactured from 2018 onward for Euro4 models. The kit is designed for use with standard or sport exhaust systems. If retaining the original carburettor, increasing the jet size by approximately 7–10% is recommended; a 19 mm sport carburettor is also recommended.
