Product details :

Features

Manufacturer's ref: VTK24570B — Complete top-end kit VERTEX (cast piston). Designed for motocross machines, this kit includes the components necessary for replacing the piston and sealing elements, in order to restore the top-end to its original geometry after wear or repair.

Cast aluminum piston (piston diameter Ø 53.950 mm)
Rings (ring set)
Piston pin
Circlips
Top-end gaskets
Needle bearing for 2T applications (4T kits include a timing chain)

Technical specifications: indicated bore 54.00 mm — diameter Ø 53.95 mm — oversize letter: B. Piston compression: standard. Material: aluminum.

This kit is aimed at riders and mechanics looking for a complete set of parts for overhauling the top-end on motocross machines. It allows for the replacement of the piston, rings, and connecting rod components in a single operation, minimizing trips back and forth to achieve a properly fresh engine. Be sure to check engine compatibility and operating clearances before installation.
