Product Details

The Wiseco PK1052 is a complete forged piston kit engineered for Kawasaki KLF, KEF, and KVF 300 ATV engines. This kit is a +1.00mm oversize offering a 77.0mm bore (Wiseco forge code 4671M), making it ideal for cylinder rebuilds on worn or bored-out cast iron lined cylinders. Compression ratio is 8.6:1, maintaining reliable, streetable ATV performance.

Complete Kit Contents:

  • Forged piston (77.0mm bore, +1.00mm oversize)
  • Matching piston ring set
  • Taper-wall wrist pin
  • Wrist pin circlips
  • Complete top-end gasket set

Wiseco Forged Piston Advantages:

  • Forged and machined in the USA at Wiseco's Mentor, OH facility
  • Forged aluminum construction delivers superior strength-to-weight ratio versus cast pistons
  • Condensed, aligned grain structure provides higher mechanical properties, impact resistance, and fatigue life
  • Designed to withstand the stress and heat of demanding powersports applications
  • ArmorGlide skirt coating reduces friction for optimized performance and longevity
  • Wiseco rings are matched specifically to Wiseco pistons — not interchangeable with other brands

Note: Cylinder sleeves must be purchased separately. Wiseco pistons must be used with Wiseco rings only. Wiseco forge number: 4671M. OEM cross-reference ring set: 3051XC (77.50mm). Top-end gasket set: W5740.
