VERTEX Complete Top-End Kit - Cast Piston (Ref. VTK24370A)
Designed for motocross riders and workshops looking to restore a top-end without chasing parts, this VERTEX kit brings together the essentials for a meticulous renovation. It includes a cast aluminum piston, rings, and all necessary assembly components: saving time on reassembly and starting fresh, ready for the track.
Ideal for the relevant displacements, this kit is aimed at demanding users who maintain their YZ 85 and other equivalent motocross machines. Before installation, check the piston/cylinder clearance and break in according to the manufacturer's recommendations. Compatible with several YAMAHA YZ 85 models (notably 2025-2026 LW Big Wheels and standard versions), verify the reference and year of your machine before ordering.
