Description

The Vertex Complete Engine Rebuild Kit (MPN: WR101-148) offers a convenient, all-in-one solution for motorcycle enthusiasts and professional mechanics seeking to refresh or rebuild their KTM 85 SX or Husqvarna TC 85 engine. This kit is designed to provide nearly all components required for a thorough and reliable rebuild, ensuring optimal performance and longevity for your dirt bike.

Each kit includes a high-quality Vertex Piston Kit, featuring a standard compression piston, piston rings, wrist pin, and retaining clips. Complementing the piston components, the kit incorporates a Hot Rods Heavy Duty crank with a stock stroke, complete with a wrist pin bearing for two-stroke applications. Essential bearings and seals are also provided, including a Hot Rods main bearing/seal kit, a Hot Rods transmission bearing kit (which includes transmission bearings, an output shaft collar, and a sprocket lock washer), a Hot Rods counter balancer bearing kit, and a Hot Rods water pump bearing and seal kit.

To ensure a complete top and bottom end seal, a Vertex complete gasket kit is included, covering all necessary gaskets, seals, and O-rings. Furthermore, the kit comes with a Hot Cams cam chain, addressing a critical component for engine timing and reliability. This comprehensive assembly of parts not only simplifies the rebuilding process but also offers significant cost savings compared to purchasing each component individually. Please note that for 'Over Size' (OS) pistons, cylinder boring and potentially re-plating may be required.

This kit is confirmed to fit the KTM 85 SX (17/14) for years 2013-2017 and the Husqvarna TC 85 (17/14) for years 2014-2017. The '17/14' designation refers to the wheel sizes, indicating a 17-inch front wheel and a 14-inch rear wheel, a common configuration for these dirt bike models. Ensure to verify specific engine and transmission details for your vehicle before purchase, although this kit is designed for the standard 85cc 2-stroke configuration of these models.
