Bolt Motorcycle Hardware 2014+ Yamaha Four Stroke Pro Pack

The Bolt Motorcycle Hardware Yamaha Pro Pack (YZPP-14) is a comprehensive 190-piece fastener kit engineered specifically for 2014 and newer Yamaha 250cc and 450cc four-stroke platforms (YZ-F, YZ-FX, and WR-F). Unlike the smaller track packs designed for trailside emergencies, the Pro Pack is intended as a complete workshop and race trailer solution. It contains the exact OEM-spec metric hardware, unique oval bodywork bushings, and oversized dimpled flanges required to properly maintain the modern Yamaha chassis.

Constructed from class 8.8 zinc-plated steel, this kit goes beyond basic frame and plastics hardware. It includes specialized components such as a full set of sprocket bolts, rotor bolts, chain adjuster screws, countershaft sprocket lock washers, and even routine engine maintenance components like oil change O-rings and drain plug crush washers. Additionally, the YZPP-14 kit features a Dzus Eliminator kit to replace the often-problematic quick-release airbox fasteners found on early 2014–2017 YZ-F models with secure, threaded hardware.

Features:

• 190-Piece Kit: A complete workshop assortment covering bodywork, chassis, driveline, and routine maintenance hardware.

• Yamaha Factory Specs: Replicates Yamaha's proprietary hardware, including specific oval bodywork bushings and dimpled flange hex bolts.

• Driveline & Braking: Includes replacement chain adjuster screws, rotor bolts, a complete sprocket bolt set, and countershaft lock washers.

• Maintenance Hardware: Comes equipped with fresh oil change O-rings, drain plug crush washers, valve stem grommets, caps, and rim lock spacers.

• Dzus Eliminator Kit: Includes the hardware necessary to convert the 2014–2017 YZ-F quick-release airbox fasteners to standard threaded bolts for improved security.

• Organized Storage: Packaged in a durable, compartmentalized plastic container for easy organization in your toolbox.

What's in the Box:

• M5, M6 & M8 Dimpled Hex Flange Bolts

• Specialized Bodywork Bushings & Flange Collars

• Complete Sprocket Bolt Set & Rotor Bolts

• Chain Adjuster Screws & Nuts

• Dzus Eliminator Fasteners

• Oil Change O-Rings & Copper Crush Washers

• Rim Lock Spacers, Valve Stem Grommets & Caps

• Thread Chasers, Cotter Pins & Fuji-Lock Nuts

Fitment:

• Fits most 2014 and newer Yamaha 4-stroke dirt bikes. Compatible models include: YZ250F, YZ450F, YZ250FX, YZ450FX, WR250F, and WR450F

Fitment Notes:

• Intention: This kit is designed specifically for modern Yamaha four-strokes. For YZ125 and YZ250 two-stroke models, or pre-2014 four-strokes can benefit but there specific kits for those models that will more specifically benefit the fitment.

• The Dzus Eliminator: The Dzus fasteneres that hold the airbox cover in place are kind of junk for those that ride hard. This kit includes Dzus Eliminator kit to convert the airbox cover mounts to accept a standard low-profile bolt, ensuring your airbox stays securely sealed regardless of how hard you grip the bike with your knees.

• Proprietary Yamaha Bushings: Yamaha utilizes unique oval-shaped aluminum bushings and specific collar lengths for mounting their plastics. Using generic hardware store bolts without the proper collars can quickly crush the plastic and crack your shrouds or fenders. This Pro Pack provides the exact factory-style collars and bushings needed to mount the bodywork correctly while allowing the plastics to flex as designed.
