§ 02 / About this part
What it is
The VERTEX PISTON KIT PRO HC TOP END Ø 78.00 C, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
High-compression internals increase torque and sharpen throttle response across the rev range. These components replace the worn assembly and gudgeon pin to refresh the upper engine. The increased dome profile requires precise fitment to maintain correct squish clearance. Sizing letters allow you to match the parts perfectly to your bore wear. Always verify ring end gap and ensure circlips are fully seated during the install. This is a technical upgrade for riders demanding more performance from a rebuild. It serves as a direct replacement for the standard OEM component while offering improved combustion efficiency.
