Air Filters For Dirt Bikes From Rocky Mountain ATV/MC

If there’s one thing that dirt bikes are good at, it’s kicking up roost on a dry motocross track or cruising a dusty mountain trail. As an off-road enthusiast, you know that dirt is simply part of the game. After all, you can’t have a dirt bike without the dirt! While sending dust flying every which way can be a lot of fun, it can be brutal on your bike’s engine. That’s why regularly replacing your engine air filter is an absolute must.

Dirt bike air filters are specially designed to withstand the rigors of off-road riding, and Rocky Mountain ATV/MC carries some of the most popular choices around. From leading brands like No Toil, Twin Air, Uni and PC Racing, you have air filter replacements to suit your particular style. (If you prefer sticking with stock air filters, check out our OEM section.) Many of our motorcycle air filters are built with dual-layer foam, capturing large dirt grains as well as minute dust particles without sacrificing your engine’s performance. This keeps your bike’s engine in top shape while allowing you to drive it for long periods of time. What’s even better is that with a little bit of cleaning and reapplication of oil, many of these filters are reusable! We also carry a variety of useful air filter accessories, including seals, filter skins and air box washing covers.

    A new review of this filter...

    I dropped a star from my original review...Why? Because these tend to come unglued at the seems. I have switch my filters to Twin Air and Moose and am much happier. IMO these aren't any better protection than cheap pre-oiled air filters (probably less) do to the seems coming undone. On a good note, when I called Uni about my one use filter, they promptly sent me a replacement, so 5 stars for Uni's customer service.

    This twin air backs up the first twin air filter

    Twin Air filters have been good to me and my equipment. Having a standing backup in a clean bag makes the service interval quick and high calibre. If you ride like you mean it, you should wrench like you mean it with proven parts. Rocky Mountain Cycle keep me supplied with what I need-quickly.

    Awesome Air Filter!

    I swapped from a K&N with an Outerswear over to this and am extremely happy with the performance & added security of a filter that traps dust particles better than an open filter design! It was well worth the money! I added an Outerwear to it and used Maxima's FFT and it's been working awesome!
