When you hit the throttle of your dirt bike, there may be any number of things going through your head. If you’re racing on a motocross track, you might be anticipating the next series of whoops. If you’re on an enduro trail, you might be watching out for fallen trees. You’re probably not thinking about your engine valves, but that doesn’t reduce their importance. Your intake and exhaust valves are continually in motion, ensuring that your engine is operating at its peak performance. If they aren’t… well, fallen trees and whoops are going to be the last things on your mind.
When it’s time to replace your dirt bike valves, Rocky Mountain ATV/MC is your one-stop shop. We carry an extensive assortment of motorcycle engine valves: intake and exhaust valves, titanium and steel valves, and more. We stock leading brands like Pro X, Faction MX and Hot Cams. And with our Parts Finder, identifying the valves you need is easy. Need CRF250R valves? How about for a YZ250F? No problem! Just enter your bike’s make, model and year. We’ll do the rest to show you what fits.
Aside from valves, we also have important accessories like spring kits or shim kits. We even stock individual shims measured down to half sizes! And with the best prices, there’s nothing better than Rocky Mountain ATV/MC!

I installed this kit in my 2008 crf450r. Install was very easy and the valves were machined to perfect specs. My own shims worked and set both valves to the required specs. I have only put a couple hours on so far but I didn't notice and power loss or problems. Can't beat this kit for the price!Read All Reviews

I was able to purchase all the parts, tools, and chemicals to do a complete top end rebuild on my 07 yz450f from RMATVMC for less than a 3rd of the cost to have it done at a local shop. Used the RMATVMC video series too! Great product Great price, arrived on time. Would recommend.Read All Reviews
