Wiseco 4896M08400 84.00mm 11.5:1 Compression ATV Piston Kit 2.00mm Oversize Suzuki

The Wiseco 4896M08400 is a high-performance forged ATV piston kit machined to an 84.00mm bore diameter at a 2.00mm oversize with an aggressive 11.5:1 compression ratio, designed as a direct-fit replacement for compatible Suzuki ATVs. Built for riders who demand more from their engine, this piston delivers the strength, precision, and reliability that Wiseco is known for across decades of motorsports competition.

Key Features:

• Forged high-silicon, low-expansion aluminum alloy construction for superior strength, reduced weight, improved heat transfer, and extended service life
• Computer-engineered piston skirt profile minimizes cylinder wall friction for improved efficiency and wear resistance
• Lightweight forging delivers instant throttle response and maximizes torque output
• Diamond-turned CNC finish ensures precise sizing with no variation for a perfect cylinder fit
• Aerospace-grade forging process compresses and aligns the aluminum grain structure, resulting in superior resistance to impact and fatigue compared to cast pistons
• 2.00mm oversize bore (84.00mm) — requires cylinder sleeving or professional cylinder boring prior to installation
• 11.5:1 compression ratio suited for performance and high-output engine builds

Kit Includes:

• 1 Forged piston
• Piston ring set
• Wrist pin (piston pin)
• Circlip set
