Apico Head and Base Gasket Set for KTM, Husqvarna and GASGAS 125/150 Two-Strokes, 2016-2023

The Apico head and base gasket set GTHBSX125 16 (Apico ref 14B001H-14B001B) gives you just the cylinder head and base gaskets for the KTM-group 125 and 150 two-strokes. It is a cost-effective alternative to a full top-end kit when you only need these two gaskets, for example for a piston change.

The gaskets are made from high-quality materials to the same specification as the OEM gaskets, and seal as well as or better than the originals.
