Haven't installed it yet but I'm confident they will be awesome!
Motosport is the only retailer that I have found that offers a full replacement plastic kit for the 07 CRF 450R from Cycra. Motosport's service was awesome as usual I recieved the order quickly. If I had to offer a suggestion, it would be that Cycra includes white fork guards with the kit, instead of the OEM "natural" guards.
Ordered these for my 2012 crf250r and they look great! Couldn't be happier with them! Picture as all of the cycra plastics except for the shrouds. I am currently waiting for graphics to come in.
