Product Details

The Wiseco W5380 is a high-quality fiber base gasket engineered for motorcycle engines with bore sizes ranging from 70.00mm to 76.00mm. Designed to meet and exceed OEM sealing standards, this gasket delivers a reliable, leak-free seal between the cylinder base and engine cases — a critical interface for maintaining proper compression and preventing oil seepage.

Key Features:

  • Fiber construction for excellent compressibility and conformability to mating surfaces
  • Wide bore compatibility — fits 70.00mm through 76.00mm bore applications
  • Exceeds OEM standards for sealing performance and durability
  • Precision die-cut for accurate fitment and consistent crush thickness
  • Resistant to coolant, oil, and combustion gases
  • Compatible with 1973–1980 Kawasaki KZ900/Z1 and KZ1000D Z1R engines

Wiseco is a trusted name in high-performance engine components, and the W5380 base gasket upholds that reputation by providing a best-in-class seal that holds up under demanding conditions. Whether you're rebuilding a classic Kawasaki or performing a top-end refresh, this gasket ensures a proper, long-lasting seal at the cylinder base.
