High-torque, everyday NARAKU 113cc cylinder kit for all scooters with 100cc Minarelli engines. This cylinder kit is not designed for the higher rev range, its strengths lie lower down. Just above the idle speed comes constant and progressive acceleration, without straining the engine at unnecessarily high revs. The drive from standstill provides excellent traffic light getaways and power on hills, even with a pillion. The noise level remains almost low. A performance improvement arises even with an original exhaust system, which makes your scooter into a great day-to-day all-rounder. Compatible for original and sport exhaust systems. The jetting should be slightly increased. Comes complete with gasket set. The original head is retained.
