TST Undertail Fairing Kit for Yamaha R3 2015+ / MT-03 2020+

If you are removing the OEM fender from your Yamaha R3 or MT-03 you will be left with an ugly recessed area and several holes. Installing the TST Industries Undertail Fairing Kit will make your bike's tail sleek and smooth again. Our Undertail looks like an OEM part that should have been there from the factory. This system installs with ease with no permanent modifications to the bike.

When you remove the OEM fender from your R3 or MT-03, you end up with an unrefined look in the tail area. We took the necessary time to develop an Undertail Fairing that would be unsurpassed in fit, style, and look. Our undertail is the only one of its kind in that it perfectly matches the lines of the bike down to the color and texture of the surrounding components. It closes off the trunk area from water and debris, and provides a mounting base for any license plate bracket that has hole spacing of 1 3/16" (30mm) on center. If you are just looking to close off the area but are not interested in remounting your license plate, this kit will be perfect for you. If you do need a license plate mount along with this kit please see our Fender Eliminator Kit ad.

We always design our products with the hope that customers think, "this is how the bike is meant to look, not how the factory released it." This system is no exception, and we believe we've accomplished that response!

FITMENT NOTE: This undertail closeout has only been verified to fit the North American models of the Yamaha R3 and MT-03. If you are outside of that market, it is your responsibility to verify fitment before placing an order.

How is this not stock for the bike? By far the easiest mod and completely changes the look of the R3 not to mention the weight advantage.

Advantages: Something like three pounds lighter
Looks completely stock
Simple install
Lightweight tag bracket had multiple holes for different plates

Disadvantages: The sticky back tag light isn't my cup o' tea. Could use a little more permanent option.

Yamaha 2015+ R3 Fender Eliminator, Adjustable Plate Mount & LED Plate Light Kits. Prompt & safe delivery of purchase (USPS Priority). Quality materials & even though it's a pretty simple product, thoughtful execution of design & manufacturing. 4.8947 Stars.

Advantages: Quality finish & materials; anodized aluminum & stainless steel. Light wiring hole position is clearly marked if you need to drill. Good installation video.

Disadvantages: Paper print Installation Sheet, Inventory List & Tool List would be handy instead of being stuck to a laptop. (3mm & 4mm Allen Wrench. 8mm & 10 mm Wrench).

Couldn't find installation of Stock Lighting to Fender Eliminator Adaptor (use light bracket between License Plate Mount & Fender Eliminator).
