Why Nikasil Is the Future of Yamaha Banshee Cylinders – Introducing the BPRATV Banshee Ares 68mm Cylinder

 

Why the BPRATV Ares Nikasil Cylinder Redefines Yamaha Banshee Performance

Why Nikasil Is the Game-Changer for Yamaha Banshee Cylinders

When building a high-performance Yamaha Banshee engine, few factors matter more than the cylinder plating. That’s where Nikasil — a nickel-silicon carbide coating — completely transforms performance and reliability.

Compared to traditional cast-iron or steel sleeves, Nikasil-plated cylinders offer a range of critical benefits:

  • - Superior heat transfer for cooler engine temperatures under load.
  • - A harder, ultra-smooth surface that reduces friction and piston wear.
  • - Increased durability and longer life between rebuilds.
  • - Lightweight aluminum construction for faster revs and better efficiency.

In short: Nikasil means more power, less friction, and better longevity—exactly what serious Banshee riders demand.

BPRATV Yamaha Banshee ARES 421cc factory ported Nikasil cylinders – designed for Dune / Play performance with triple exhaust ports, large water jackets, and precision cooling for maximum reliability and power.

Athena, CPI Cub & Nikasil Cylinders: The Proven Standards

Performance riders have long trusted Athena Banshee cylinders and CPI Cub Banshee cylinders for their use of high-quality Nikasil plating. Both options have set the standard for durability and power output.

  • - Athena cylinders: known for strength and engineering precision, but typically at a higher price point.
  • - CPI Cub cylinders: loved for raw power delivery and robust Nikasil coating performance.

However, riders wanted something that offered Athena-level performance without the premium cost. Enter the BPRATV Ares Cylinders—a true evolution of value and design.

BPRATV Yamaha Banshee ARES 421cc factory ported cylinders – precision-machined aluminum Nikasil design with Dune / Play porting, large exhaust openings, and high-flow architecture for maximum power and cooling.

The BPRATV Ares 68mm Nikasil Cylinder: Built for Power, Priced for Riders

The new BPRATV Banshee Ares 68mm Cylinder delivers everything riders love about Athena—minus the inflated cost. Designed specifically for Yamaha Banshee builds, it’s Nikasil-plated for unmatched smoothness, cooling efficiency, and strength.

Each Ares cylinder is factory ported with a Dune / Play port design that delivers hard-hitting midrange power and a screaming top-end. This isn’t just a stock casting—it’s a true performance cylinder built by riders, for riders.

Truly Ported – No Gimmicks, No Games

When we say ported, we mean it. Every BPRATV Ares Cylinder comes ported from the factory with a Dune / Play performance design that produces explosive midrange torque and crisp top-end RPM.

Don’t be fooled by so-called “Triple Ported” cylinder claims—those simply refer to the number of exhaust ports (ours have three as well). The difference is that ours are actually performance-ported for real horsepower gains, not marketing fluff.

Key Features:

  • - 68mm bore size – adaptable for 392cc to 421cc depending on crank setup.
  • - Factory Dune / Play porting – real midrange punch and strong top-end performance.
  • - Enlarged water jackets – increased cooling capacity for sustained performance.
  • - Triple exhaust ports – delivers a broad, responsive powerband across RPMs.
  • - Nikasil coating – minimizes friction, maximizes reliability and lifespan.
  • - Lightweight aluminum alloy – enhances throttle response and top-end strength.
