Improve throttle response and power delivery with Boyesen 612 dual-stage motorcycle reeds. Designed for riders seeking more responsive engine performance, these replacement reed petals use a two-stage design to provide quicker opening and closing, enhanced low-throttle response, and improved intake flow. The result is stronger performance across the operating range while maintaining dependable operation for off-road and competition motorcycles.
Boyesen dual-stage reeds are engineered to deliver greater air velocity and increased flow area compared with conventional reed designs. This allows the engine to respond more quickly to throttle input and helps support improved horsepower throughout the powerband. The durable construction also promotes longer service life, while the design helps prevent engine damage if a reed breaks during operation.
These Boyesen 612 motorcycle reeds are designed for fitment on select Husqvarna two-stroke models, including 1973, 1974, 1976, 1977, 1978, 1979, 1980, and 1981 Husqvarna WR 250 motorcycles, as well as 1977 and 1978 Husqvarna CR250 models. Verify the motorcycle model year and existing reed assembly before installation to confirm proper application. Manufacturer part number 612 and vendor part number 59-7612 identify this replacement reed component.
