Vertex Piston Kit, Vertex small end bearing and Vertex top end gasket set.

Fits KTM EXC300 TPi 2018-2023. Graded size 71.925 A. The clearance is to allow for piston expansion when it heats up.

 Vertex pistons are manufactured using exotic aluminium alloys called Low-Ex (low expansion) Silicon charged with 12%, 18% or 21% depending on the application. Vertex pistons are manufactured using either a gravity cast or hydraulic forging process to make the blank parts and then the material structure is refined using a hi-tech Heat Treatment completed in an automatic HT implant with solubilization by quench in hot water. This heat treating process is cutting edge technology for this type of aluminium alloys.

The machining process is completed using the latest CNC machines and software as well as the usage of diamond tools. By using this high tech tooling, specific surface finishes can be achieved depending on the final application of the finished piston. Every Vertex piston passes through a rigorous manual and automatic quality control process to insure only the highest quality level.

Vertex pistons are coated with a special Molybdenum Bisulphite black coating to aid during piston break in and reducing friction during the work inside the cylinder. Recently, following the latest developments used in Formula One engines, Vertex has introduced a new, all over, Phosphate Coating which has a slight hardness increase combined with a light surface porosity that exhibits superior adhesion qualities of the Molybdenum Coating, extending the coating durability for twice as long.

We reccommend when fitting a new piston kit to a used cylinder that you have the bore honed.

This honing method leaves a functional cross hatched effect on the cylinder to help retain 2 stroke oil in the bore which aids the piston and bore life.

Oversize pistons are available for certain models with boreable liners fitted.

We combine these advanced materials with state-of-the-art manufacturing processes to provide custom-tailored solutions to meet the needs of each individual customer. Our design engineers have the ability to analyze the environment the gasket will perform in, select the proper material, and apply the appropriate technology to offer the highest performing gaskets available on the market.

To ensure superior performance across a wide variety of engine types and sizes, we manufacture our gaskets from a wide range of materials. Whether the situation calls for the latest in advanced technology like our multi layer steel gasket or a synthetic blend fiber, ProX offers a wide range of products your application will suit.

Prox gaskets are manufactured by high quality factories to ProX specifications to ensure top quality sealing. Precision engineering and the use of first class materials guarantee the quality you demand from a gasket. The gaskets are complementary to our pistons and rods, so we developed a top end gasket kit and complete gasket kit.
