Wiseco 4714M09200 ATV Forged Piston Kit 92mm 2.0mm Over 13.5:1 Compression

The Wiseco 4714M09200 is a high-performance forged piston kit designed for ATV applications, featuring a 92mm (2.0mm over) bore diameter and a 13.5:1 compression ratio. Engineered for the rigors of high-performance and racing use, this piston is a direct replacement upgrade for select Kawasaki and Suzuki 400cc sport ATVs.

Wiseco forges all of its pistons in-house in the USA, maintaining strict control over every stage of the manufacturing process — from raw aluminum bar stock through final skirt coating. This vertical integration ensures consistent quality and dimensional accuracy across every unit produced.

Key Features:

• Forged aluminum construction — superior strength, toughness, and fatigue resistance compared to cast pistons
• 92mm bore diameter — 2.0mm over stock for use with a bored or sleeved cylinder
• 13.5:1 compression ratio — optimized for high-performance ATV applications
• Condensed, aligned grain structure — provides higher mechanical properties and resistance to impact and fatigue failure
• Optimized strength-to-weight ratio — reduces reciprocating mass while maintaining durability under extreme loads
• Skirt coating applied — reduces friction and improves break-in characteristics
• All forge tooling made in the USA — Wiseco controls the entire manufacturing process domestically

Compatible with the Arctic Cat DVX 400 2x4 (2004), Kawasaki KFX400 (2003–2006), and Suzuki LT-Z400 QuadSport (2002–2009). Intended for use with a cylinder bored to 92.00mm. A complete piston kit typically includes the piston, rings, wrist pin, and circlips.
