Applied Smog Block off Kit CRF450X 2005 - 2010

The Applied Smog Block Off Kit is a great way to increase performance on your CRF 450x. It also removes a pound or two from your bike. I do suggest that you use the applied vent kit at the same time. To wake this bike up, get the FMF 4.1 slip on, Nicoll Racing custom jet kit, small air box mod, and applied smog and vent kit. For not a lot of money you will be very happy.
