Dirt Bike Front and Rear Fenders

What would a good moto be without flying roost? It’s part of the fun, and it wouldn’t be quite as exciting without the roost flying. Even so, a certain level of protection is required for both you and your bike. That’s where fenders come in. They help control the mud, dirt and water that are thrown from the tires, keeping all debris safely out of your way. Without fenders, roost could turn from a bit of fun and excitement into a safety hazard.

But that’s not the end of it – there’s also the rugged looks of the machine. Rocky Mountain ATV/MC carries replacement front and rear fenders in a variety of styles and colors to help you get the perfect look for your bike. We carry brands that are known for their high quality plastics: Acerbis and Polisport. (If you’re just looking for OEM replacements, click the OEM button at the top of the page to see what we have available.)

Fenders are an important part of every dirt bike for both safety and aesthetic reasons. When it’s time to replace them, count on Rocky Mountain ATV/MC. Take a look at your options, and see how you can spruce up your bike with a new fender.

    Inexpensive option but not lost to OEM quality

    The OEM plastics might be made by polisport but there's definitely a difference between OEM and OEM-replacement as far as quality. This was a a lot softer and more flexible than the OEM and when I screwed on the under fender they dimpled the fender and there's two whitish bumps. I don't really care at all about that but if you wanted OEM quality the Acerbis is the better budget option to OEM.

    Great stock replacement with a newer color scheme

    This mounted right up and replaced my OEM plastic perfectly. I changed up the color and it looked great on the bike.
