Complete one-box solution for a professional 2-stroke engine rebuild. This VERTEX kit combines a piston kit, heavy-duty crank and all key bearing, seal and gasket components to refresh your 85cc engine reliably.
This VERTEX Complete Engine Rebuild Kit for 2-Stroke is the convenient, one-stop “rebuild in a box” designed to help you restore performance and reliability with a thorough, professional-level refresh. Instead of chasing individual parts and risking mismatched components, you get the major wear items and critical hard parts together in one complete kit.
It’s ideal when your engine needs more than a top-end—covering key areas like the crank, bearings, seals and gaskets, so you can address common rebuild issues such as air leaks, worn bearings, tired crank assemblies and coolant-side seal wear in one go.
