Mud Flaps & Splash Guards
About Mud Flaps & Splash Guards
A mud flap hangs behind a tire to stop water, mud and stones from being thrown at you, at the bike behind you and at the underside of the bike. Riders come here to replace a torn or missing flap, to add a flap to a cruiser for looks, or to fit a rear mud plate or roost deflector to a dirt bike. The category has two distinct kinds of part.
Dirt bike parts are model-specific. The listings here include rear mud plates for bikes such as the Kawasaki KX 85 and KX 250/450 F and Honda CRF 250 R and 450 R, flaps for Yamaha and Honda, and a number-plate roost deflector. They match the fender or the swingarm's mounting points, so check the model and years.
Cruiser and road flaps are sold by size, with listings such as 9-1/2 inches wide by 6-1/2 inches high and 10-1/2 inches by 8 inches, in plain, studded and custom designs. Measure the space behind your tire and your fender's mounting holes before you buy. Leave clearance so the flap does not rub the tire when the suspension compresses.
Brands in this category include UFO, Cycra, Moose Offroad and Drag Specialties. Pick your machine in the Ride Finder at the top of the page. For other protection, see Fork Guards & Covers, Radiator & Oil Cooler Guards and Skid Plates, Sliders & Spools, all part of Guards & Protection.
FAQs on mud flaps and splash guards
What size mud flap do I need?
Measure the width of your fender and the space between the fender and the tire. Cruiser flaps are listed with a width and height, such as 9-1/2 inches by 6-1/2 inches. Choose one that fits the mounting holes and leaves tire clearance.
Will a mud flap fit any fender?
Not always. The mounting holes and fender shape differ between bikes. Cruiser flaps commonly bolt to the fender or license plate area, and dirt bike plates are model-specific, so check the listing.
What does a roost deflector do?
A roost deflector is a shield, often combined with a number plate, that redirects dirt and stones thrown up by a tire away from you or from parts of the bike. Check the listing for the model it is made for.
Will a mud flap stop all water spray?
It reduces spray and thrown debris, but it will not stop all of it. Its size, shape and position all affect how well it works, so a flap that fits your fender is more useful than a generic one.
How do I mount a mud flap without it rubbing the tire?
Leave a gap between the flap and the tire, and check it with the suspension compressed. A flap that is too long or too close can rub the tire. Follow the listing's instructions.
