Product Details

The Wiseco CK177 is a complete top end piston kit engineered specifically for the Yamaha Road Star 1600, delivering a 95.00mm bore and 10.5:1 compression ratio with a domed piston design for a total displacement of 1602cc. Forged from aerospace-grade aluminum alloy, this kit is designed and manufactured in the USA to deliver a superior combination of performance, durability, and precise fitment over OEM cast pistons.

Wiseco's dedicated forgings offer an improved tensile strength and optimized strength-to-weight ratio compared to cast alternatives. The domed piston profile promotes improved flame travel for more efficient combustion, while detailed skirt geometry ensures stability and smooth cylinder bore operation. Each piston is machined to the tightest tolerances and engineered with the correct installed clearance to produce maximum power, minimal wear, and a reliable seal at operating temperature.

Kit Includes:

  • Forged aluminum domed piston — 95.00mm bore, 10.5:1 compression ratio, aerospace alloy construction
  • High-performance piston ring set — engineered for extended service life and sustained power output
  • Alloy wrist pin — precision machined for consistent trueness and durability
  • Circlips — for secure wrist pin retention
  • Top end gasket kit — premium materials exceeding OEM sealing standards, includes head gasket, base gasket, and O-rings

Built on race-proven designs trusted by top-level race teams across all motorsport disciplines, the CK177 is an ideal solution for a standard bore top end rebuild or a performance upgrade on the Yamaha Road Star 1600.
