Wiseco VT2784 Milwaukee-Eight 107 CID Forged Piston Kit 11:1 Compression

The Wiseco VT2784 is a high-performance forged piston kit engineered for the 2017 and later Harley-Davidson Milwaukee-Eight 107 cubic inch (1745cc) engine. Built to an 11:1 compression ratio, this piston delivers a meaningful power and torque upgrade over stock, making it ideal for riders seeking more aggressive street or touring performance from their M8-powered Harley.

Wiseco manufactures all of its pistons in-house in the USA using a proprietary forging process that produces a stronger, lighter piston than cast alternatives. The result is improved throttle response, greater durability under high heat and load, and tighter tolerances right out of the box.

Key Features:

• 11:1 Compression Ratio – Increased compression for improved power and torque over the stock 10.0:1 ratio
• USA Forged Construction – Forged aluminum alloy for superior strength-to-weight ratio versus cast pistons
• In-House Manufacturing – Forged, machined, and finished entirely at Wiseco's Mentor, Ohio facility
• Dyno-Developed Design – Validated through extensive R&D and dyno testing for real-world performance gains
• Precision Fit – Engineered to OEM bore specifications for the Milwaukee-Eight 107 CID engine
• Industry-Leading R&D – Decades of motorsports experience applied to V-Twin performance applications

Wiseco's VT2784 piston kit is a popular foundation for Milwaukee-Eight engine builds, frequently paired with performance cams, heads, and exhaust upgrades. Whether you're building a street cruiser or a high-output touring machine, Wiseco's forged V-Twin pistons provide the durability and performance consistency professionals and enthusiasts demand.
