Yamaha Banshee Triple Ported 370cc Big Bore Cylinders with Pistons – Built for Serious Power

Unlock extreme performance with the Banshee Triple Ported 370cc Big Bore Cylinders with Pistons, a high-performance upgrade designed for riders who crave aggressive power delivery and race-ready speed. This setup isn’t just an engine rebuild—it’s a full-blown transformation built to push your Yamaha Banshee to the limits.

The 370cc Big Bore Cylinders significantly increase displacement over the stock 350cc setup, offering more torque, greater top-end horsepower, and a wider powerband. What sets this build apart is the triple porting, a performance porting process that dramatically improves airflow, fuel delivery, and combustion efficiency. The result? A high-revving, hard-pulling engine that excels on the dunes, track, or trail.

Each cylinder is precision-machined from durable aluminum and coated for optimal wear resistance and heat management. The triple porting ensures maximum intake and exhaust flow, giving you the crisp throttle response and brutal acceleration that the Banshee platform is famous for—amplified.

Paired with high-performance pistons, this kit is engineered for reliability under high stress. These pistons are built to handle the increased compression and temperatures that come with high-output builds. With proper tuning, you’ll experience explosive performance without sacrificing long-term durability.

Ideal for experienced builders and riders looking to compete or dominate in open terrain, the  Ported 370cc Big Bore Kit offers serious gains and a noticeable difference from stock or lightly modified builds. This setup is recommended for use with upgraded carbs, exhaust systems, and ignition components to fully unleash its potential.

If you’re ready to experience what a fully unleashed Banshee feels like, are your ticket to unmatched power and performance.
