Vertex Piston Kit Cast Replica 24212C — KTM/Husqvarna/Gas Gas 85cc 2003-2024 (46.96mm)

Product Description

Bring back the sharp throttle response and peak power of your 85cc 2-stroke machine with the Vertex Cast Replica Piston Kit (24212C). Precision-engineered as a direct factory OE replacement, this 46.96mm piston is designed for a wide range of KTM, Husqvarna, and Gas Gas 85cc platforms manufactured between 2003 and 2024.

Vertex cast pistons are constructed from an 18% silicone-content gravity-cast aluminum alloy. This advanced metallurgy significantly reduces thermal expansion, ensuring the piston maintains its exact shape under the intense heat cycles of 2-stroke competition. Combined with a factory-applied Molybdenum Disulphite (MoS2) skirt coating, this kit guarantees accelerated break-in times, reduced internal friction, and an extended top-end lifespan.

Frequently Asked Questions

Q: Is this piston suitable for my cylinder?
A: This 46.96mm piston is an "A" or standard size replica meant for a healthy, factory-spec 47.00mm bore cylinder. We always recommend measuring your cylinder bore with a precision gauge to confirm the clearance is within service limits before assembly.

Expert Pro-Tip: Always block the crankcase opening with a clean rag during circlip installation. This simple step prevents an accidental slip from dropping a circlip into your engine's bottom-end, saving you from a major headache.
