The Cycra Powerflow Intake Shrouds are the next performance leap in technology. 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 Cycra's patented venturi effect scoops that pump air into the airbox.


  • 40% airflow increase to airbox.
  • Dramatically reduces radiator, fuel tank and cylinder head temperatures.
  • Slimmer than stock.
  • One-piece shroud design.
  • Stronger and lighter than stock.
  • Sold as a pair.
  • Made in the U.S.A. by Cycra.
  • Note: Optional Cycra Fuel Tank Cover (sold separately) one-piece design is slimmer and lighter than stock.

The shrouds have gone through extensive testing with the factory race teams. From the racers' input, Cycra has 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. Cycra's Powerflow airflow scoops bypass the radiators and deliver cool air to the cylinder heads and fuel tank. The bypass airflow around the radiators uses 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.

Kinda disappointed

Bought for my 2014 yz250f. the positive is that it does make the bike skinner, which made the bike way more comfortable to ride. The negative is that the plastic is really weak, after 3 rides there are stress marks in about 5 spots

Bought the new one piece shrouds for the 2014 yz250f and rode with them twice and after that, blew up my motor!!! There's less than 5 hours on on my bike. They suck in way too much air and dirt!! I would not recommend these to anyone!!!!!

Great product made in USA!

I purchased these shrouds for my 2014 crf450. I was hesitant after reading the review about fitment from another customer. After recieving the shrouds, they fit perfect. There is a notch cut in the scoop inside the shroud that your radiator guard fins fit into. I don't know why the other guy said he had to cut these. Anyhow the color is very close to the factory red. I matched these with red acerbies side panels and rear fender. The acerbies is a closer match to the factory red but like I said they cycra red is so close that you can't really tell a difference.

Good shrouds but don't fit my bike

For some reason it is taking companies forever to come out with solid red shrouds for the 13 honda crf 450r / 14 crf 250/450. Acerbis offers solid white, solid black, and then red white oem style. I bought the Cyrca shrouds to get a solid red shroud mainly; the added air scoops were just a plus. However, I am running works connection radiator braces on my bike and the shrouds do not fit with radiator braces on. It also looks like you have to cut almost your whole first louver/grill fin off in order to make them work on the 13/14 hondas. I found this out after installing new graphics on the shrouds! :(

It's a good idea that works

I've had a set of these on my KTM for a couple of years now, and can say that they bolt right up without any unwanted drama, and hold up well to use and most abuse. I say most because there are some people who can wreck anything. They are well made and really do flow more air through the rads. If you have a bike that tends to run hot, or live and ride in the desert like me, they can make a substancial difference. There are 2 negatives about them though, although they are almost being nit-picky if you will. First they add about 1/2" to 3/4" width to the bike at their forward edge. And second, if you put graphics on them, there is a bit of trimming to be done. Overall I'm glad I have them, and wouldn't hesitate buying them again. Whether or not you should have some too, is as always, for you to decide.

They do help keep it a few degrees cooler then without, also if you add the front fender then temp drops even more due to added air flow. The only draw back for the racer or guy who is worried about looks is that you have to make a few cuts on your sticker kit to fit right. Not a big deal if you do it right you cant tell anyways.

They do keep the bike about 5-10 degrees cooler but if you want to put a graphics kit on them you have to cut the graphics to shape it to fit this shroud.

I have a 05 crf250r and i was wondering if the 06 shrouds would fit the same?
My bike is an 05 with a 06 subframe, seat, fender, exhausts, side plates, and airbox, so i don't know if i should just get the full kit or not...

Yes, According to Acerbis the Powerflow Shrouds would be the same for the Honda CRF250R from 2004-2009. The 2006 shrouds would actually be the same as the shrouds on your 2005 so the plastic kit for the 2006 model should fit your bike just fine.

Will the cycra powerflow radiator shrouds work with graphics I would typically get when I order them for my bike?

The Cycra Radiator shrouds will be the same shape as the OEM shrouds. So the graphics you typically purchase will fit.
