The Cycra Powerflow Intake Shrouds are the next performance leap in technology for Yamaha. These intake shrouds improve the airflow to the airbox by a whooping 40%. This eliminates the throttle lag off the bottom and allows the motor to run freer. This is done by increasing the volume and using our patented venturi effect scoops that pump air into the airbox.
The shrouds have gone through extensive testing with the Factory Yamaha Race Team. From the racers input we have slimmed and simplified the shrouds to a clean one piece design instead of the complex two piece unit. The slimmer shrouds give the riders improved feel of the bike with a smooth outer shell.
The simpler shrouds improve the ability to maintain the airbox with fewer fasteners and pieces while saving weight.
Even with all these updates, most aftermarket graphics will fit the shrouds with little or no modification. The Smooth surface makes decals easier to apply and resists pealing.
The patented Cycra Powerflow Technology dramatically reduces Radiator, Fuel Tank and Engine Head Temperatures. Cycras Powerflow airflow scoops bypass the radiators and deliver cool air to the cylinder heads and fuel tank. The bypass airflow around the radiators using the venturi effect that actually pulls the air from behind. This kind of technology has been only used on aircraft and formula one race cars.
