It provides smoother operation, reduced friction, and maximum reliability under high RPMs.Raptor 660 R CP Stroker Piston 102mm Big Bore Cylinder 719cc Top End Rebuild Kit

• 719cc Big Bore Cylinder:
  The oversized cylinder expands your engine’s displacement from 660cc to a massive 719cc, allowing for increased airflow and fuel mixture. This directly translates to more torque, more horsepower, and significantly improved throttle response. Precision-machined to factory specifications for a perfect fit and finish.

• Top-End Gasket Set:
  Premium gaskets made to withstand high heat and pressure for a leak-free, reliable seal. Ensures consistent compression and protection against blow-by under heavy load.

• Piston Rings, Wrist Pin, and Circlips:
  Complete piston assembly hardware included, ensuring a seamless and secure top-end rebuild. The rings are designed for superior oil control and compression retention.

⚙️ Performance Enhancements:

• Significant Displacement Increase:
  Jump from the stock 660cc to a robust 719cc for improved power throughout the entire RPM range.

• Aggressive Throttle Response:
  Instant power delivery from low-end through mid-range, ideal for rapid acceleration and tight trail maneuvering.

• Improved Heat Management:
  The forged CP piston offers enhanced heat resistance, making it ideal for aggressive or extended riding sessions without overheating.

• Enhanced Torque for Utility Use:
  Greater low-end torque helps with pulling, climbing, and pushing through deep terrain like mud, sand, or snow.

• Stronger Compression Ratio:
  Boosts combustion efficiency, power output, and overall engine responsiveness.

🏍️ Ideal Applications:

• Trail Riding & Backcountry Exploration

• Sand Dunes & Desert Racing

• ATV Drag Racing & Track Use

• Heavy-Duty Utility Work (plowing, hauling, etc.)

• Performance Engine Rebuild Projects

This kit is perfect for both performance enthusiasts and utility riders looking for reliable power, longer engine life, and smoother operation in any environment.

💥 Why This Kit Stands Out:

• Premium Brand Components: CP Pistons are widely known for precision engineering and championship-grade reliability.

• Designed for the Raptor 660R: Direct-fit components make installation straightforward with proper mechanical experience.

• Complete Top-End Solution: Everything needed for a full top-end rebuild is included—no guesswork, no mismatched parts.

• Built for Riders Who Push Limits: Whether you’re riding for fun, racing competitively, or working in rugged terrain, this kit keeps your Raptor performing at its peak.

🔧 Installation Note:

Professional installation is strongly recommended to ensure correct assembly, clearance checking, and proper engine tuning. To maximize performance, pair this kit with a fuel controller, performance exhaust, and upgraded intake system.
