If you are gunna be riding anything other that dunes, dont cut the rears.
Not really... I mean there is the potential wieght saved because that's one less place for dirt/mud to cake onto. When I use to race 7s I would crawl under my truck between moto's and beat the mud off to cut down on wieght. Use to save me about 100-200lbs on the hole shot depending on how much water was layed down.other than looks...do you guys have any reason for cutting fenders?
