The Graves Motorsports Velocity Stack Kit is specially designed to suit the new fuel-injected Yamaha motor. These new intake stacks mount directly into the stock airbox (or Graves Ram Air Box) without modification and are designed to smooth out the power curve, increase horsepower throughout and improve fuel efficiency. Power gains of up to 6 HP in the mid-range and 2 HP at the top-end are not uncommon.
- Developed to smooth out the power curve, increase horsepower throughout and improve fuel efficiency.
- Note: Contents vary by fitment.
Notes: The plastic ridges at the top of the airbox need to be removed (see video HERE). Stock bikes the larger velocity stack install on the ride side of the motorcycles. Race bikes equipped with the Graves' velocity stacks, WORKS2 full exhaust, DNA air filter and Graves FTEcu flash: you will install the taller stack on the left side of airbox.
