Replace your original piston with a sturdy replacement part using this TECNIUM forged piston kit Ø66.00 mm. Designed for the Quad and Roadster universes, this forged-type piston is aimed at riders and tuners looking for a reliable reconditioning part for Yamaha 350 cc engines. The finish and forged manufacturing meet the machining and fitting requirements on a bore of Ø 66 mm, standard compression.
This kit is suitable for common replacements on several Yamaha 350 cc models — notably the YFZ 350 BANSHEE (2006-2007) and the RD 350 LC (1992) — but always check the bore and engine tolerances before installation. Ideal for engine refurbishment, it integrates into piston operations, axial play checks, and ring installation. To ensure a safe installation, follow the manufacturer's recommendations and have the installation performed by an experienced mechanic if necessary.
