About the Product

Graves Motorsports Yamaha R1 Velocity Stack Kit for the 2002-2003 model sport bikes. The Graves Motorsports YZF-R1 Velocity Stack Kit is specially designed to suit the new fuel injected Yamaha Motor.

The kit contains two rubber intake stacks that replace the stock intake units 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.
