RZV500R Boyesen Dual Stage Reed Valves

RZV500R Boyesen Dual Stage Reed Valves

Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs.

The Benefits:

  • Quicker acceleration for that all-important holeshot
  • Crisper throttle response for fast corner exits and surer jumps
  • More horsepower throughout the powerband for guaranteed performance
  • Improved engine efficiency and fuel economy for the long distance rider
  • Longer life - Boyesen Power Reeds outlast all other aftermarket reeds

Supplied as a complete engine set to suit:

RZV500R 1984-1986
