The Vertex MN 5Q6J piston kit is an excellent choice for Yamaha YZ85 engine enthusiasts seeking high-performance upgrades. This piston kit, manufactured in 2019, is specifically designed to fit the Yamaha YZ85 engine and guarantees enhanced power and efficiency.
The pistons in this kit are meticulously crafted from high-quality forged aluminum alloy. Forged pistons offer greater strength and durability compared to cast pistons, allowing for increased power output and longer engine life. Each piston is precision-machined to ensure optimal engine clearance and compression ratio.
The Vertex MN 5Q6J piston kit comes with two pistons one for the standard engine configuration and another for the power valve (PBVS) system, making it a versatile option for riders. Both pistons feature a designed crown to maximize combustion efficiency and promote better power delivery across the entire rev range.
The piston skirt is surprisingly thin, contributing to a lighter reciprocating weight, which results in smoother engine operation and reduced vibrations. This enhances the overall riding experience, providing increased throttle response and improved engine response.
The Vertex MN 5Q6J piston kit also comes with rings, including an olive oil ring and two compression rings, ensuring proper sealing to ensure optimal engine performance. The rings are precision-machined to fit perfectly on the piston, ensuring a snug fit and preventing any unwanted oil or combustion gas leaks.
