Banshee 421cc ARES 68mm Cylinders Wiseco Pistons Athena Style Ported Top End Kit

Yamaha Banshee ARES 68mm Cylinders by BPRATV – Athena Nikasil Performance at a Fraction of the Cost!

✅ Unleash Athena-Level Power at a Fraction of the Cost

The BPRATV Banshee ARES 68mm Cylinder Kit is engineered for riders who want serious horsepower, reliability, and value. Featuring factory pre-ported dune/play port design, larger water jackets, and triple exhaust ports, this kit is ready for +4mm stroker builds—no spacer required.

🔥 Built to Perform – Complete Top End Kit

• Banshee ARES 68mm Nikasil Cylinders – pre-ported for dune/play powerband
• Larger water jackets for superior cooling
• Triple exhaust ports for a wide, responsive powerband
• TRULY PORTED – No Gimmicks, No Games. When we say ported, we mean it. Every cylinder is factory ported with a dune/play design that delivers hard-hitting mid-range pull and screaming top-end power for all-around performance. 
  • Don’t be fooled by “Triple Ported” Cylinder claims — all that means is the cylinder has three exhaust ports (ours do too). What sets us apart is that our cylinders are actually performance-ported for real gains, not just marketing jargon. 😂
• Wiseco Pro Lite Forged STROKER Pistons with rings, pins, and circlips
• Heavy-duty wrist pin bearings
• Special cut 68mm big bore 4mil stroker domes (22cc)
• Cometic one-piece fiber base gasket, intake gaskets, and cool head O-ring kit*

🚨 Port Timing Is Critical – Don’t Skip It

This 421cc setup must be ported properly. These cylinders are dune/play ported by design, however, the port timing is made for a 392cc/400cc configuration. Slapping in a thick base gasket is NOT a real fix and WILL rob your Banshee of its true potential!

• Correct port timing to match 421cc stroke
• Use BPRATV’s in-house porting service for maximum performance

✅ What Makes Nikasil Special?

When it comes to building a high-performance Yamaha Banshee, Nikasil (nickel-silicon carbide plating) is a game-changer.

• Transfers heat more efficiently, keeping your motor cooler
• Provides a harder, smoother piston surface, reducing friction
• Lasts longer between rebuilds thanks to durability
• Lightweight aluminum design for stronger performance

Athena vs CPI Cub vs BPRATV ARES

Athena and CPI Cub cylinders have long been the benchmark for Banshee builds. Athena delivers strength at a higher price, while CPI Cubs are known for raw performance and Nikasil durability. The BPRATV ARES cylinder bridges the gap—offering Athena-level performance at a fraction of the cost!

✅ Key Features of the BPRATV ARES Cylinder

• 68mm bore size – runs 392cc to 421cc depending on setup
• Larger water jackets for enhanced cooling
• Triple exhaust ports for responsive, wide powerband
• ACTUALLY PORTED with dune/play port design (strong mid-range pull and screaming top-end power for all-around performance)
• Nikasil plating for superior strength and low friction

Tested Across Banshee Builds

Proven across real-world setups:
