Boyesen Power Reeds Yamaha YZ250 / WR250

Boyesen's dual-stage reed valves offer a significant upgrade for 2-stroke engines, providing enhanced performance especially during high RPM operation. The product features a cleverly designed pair of reeds: a flexible top reed combined with a sturdier, flow-through base reed. This arrangement ensures optimal intake regulation and air velocity, translating to swift acceleration, precise throttle response, and a noticeable boost in horsepower. Riders looking to eclipse their stock reed valves will find Boyesen's dual-stage reeds as an exceptional choice for consistent power delivery across the entire RPM spectrum.

• Dual stage OEM replacement reeds
• Minor change gives major H.P. improvements
• Faster opening and closing
• Greater low pressure (Low-throttle) response
• Greater velocity and flow area
