VELOCITY STACK KIT

The Graves Motorsports YZF-R1 Velocity Stack Kit is specially designed to suit the new fuel injected Yamaha Motor. The kit of two rubber intake stacks replace the stock intake stacks on the #2 and #3 cyclinders. 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.
