Improve intake performance with Boyesen 615 dual-stage motorcycle reeds. Designed as a direct-fit reed replacement for select Kawasaki two-stroke models, these reeds help optimize air-fuel flow through the intake system while maintaining dependable operation. The dual-stage design uses reed petals that respond efficiently across the engine's operating range, supporting improved throttle response and stronger overall performance.
Boyesen 615 reeds are engineered to open and close faster than conventional reed designs. This faster response can help improve low-pressure, low-throttle operation while increasing intake velocity and available flow area. The result is more consistent engine response and improved power potential from a minor component upgrade. The reeds are also designed for extended service life and will not cause engine damage if a reed breaks, providing an added measure of protection for the engine.
These Boyesen motorcycle reeds fit 1983-1986 Kawasaki KX250 models and 1984-1987 Kawasaki KXT 250 Tecate models, along with 1987-1988 Kawasaki KXF 250 Tecate 4 models. Verify the motorcycle year and model before installation to ensure proper fitment. Manufacturer and vendor part number 615 identifies this Boyesen replacement reed assembly.
