Vertex Pistons 98-00 YZ 125 Complete Engine Rebuild Kit

Vertex Pistons is known for making well-built engine components, and this complete engine rebuild kit for your 1998-2000 Yamaha YZ 125 is a prime example. If you're looking to bring your engine back to life or prepare it for a demanding season, this kit bundles all the essential parts you'll need for a comprehensive overhaul. It's designed to save you significant time and money compared to sourcing each component individually, offering an average savings of $400 over OEM parts.

This isn't just a collection of random parts; it's a curated package built around a heavy-duty crankshaft from Hot Rods, ensuring a strong foundation for your engine. You'll also find a Hot Rods counter balancer bearing kit (if your model uses one), a main bearing and shaft seal kit, and a transmission bearing kit, all from Hot Rods to cover critical rotating assemblies. The kit also includes a water pump rebuild kit to keep your cooling system in top shape, and a Hot Rods wrist pin bearing. Vertex Pistons contributes their replica piston kit, which may be available in oversized options for specific applications, along with a complete gasket and oil seal kit to ensure everything seals up tight. If your YZ 125 uses a cam chain, a Hot Cams cam chain is also included where applicable.

Putting together a full engine rebuild can be a daunting task, especially when you have to research and track down every single part. This kit streamlines that process, giving you the confidence that you have the right pieces from reputable brands to get the job done right. It's a smart way to ensure your engine gets a fresh start with quality components.
