Apico Head and Base Gasket Set for KTM, Husqvarna and GASGAS 125/150 Two-Strokes 2023-2027

The Apico head and base gasket set GTHBSX125 23 (Apico ref 14B001H-14H903B) gives you just the cylinder head and base gaskets for the latest 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.

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.
