Tecnium segment set designed for the refurbishment of Minarelli pistons (vertical and horizontal). Ideal for urban scooter riders looking to replace worn segments and restore proper engine sealing without changing the entire piston/cylinder assembly. This set is calibrated for a piston diameter of 40 mm with a segment thickness of 1.5 mm.
Segments are an essential wear part for compression and oil control in 2-stroke engines. Replacing the segments during refurbishment helps limit compression losses and reduce oil consumption. Installation is recommended in a workshop or by a qualified mechanic: check the condition of the piston, housing, and cylinder before installation and adhere to the manufacturer's assembly tolerances.
Product suitable for 50 cc scooters using Minarelli engines, for example:
