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.

    Works great

    I wanted to swap a 2018 fender and number plate on to my 2003 YZ85 to make it look newer. Turns out that the 2018 plastics bolt right on to the older bikes, no mods needed. Great fender.

    i bought this fender to replace the funny looking fender on the Gen 2 KLR. Install was simple and took maybe 10 minutes. The day after I put it on, I crashed in some deep sand and the bike suffered no damage.It's a good way to improve the looks over the stock fender.

    Worth it

    It is a huge improvement over the stock look it did require a drill to counter sink some holes but no big deal it was still only a 20 min install

    Fit, color, and value is great

    The plastics color matches stock perfectly. The fit was perfect and Polisport kits always long up great. That is rare with aftermarket plastics.
