UFO and Acerbis are the two biggest aftermarket brands making OEM-style motocross plastics — fenders, radiator shrouds, and full body kits — for dirt bikes and off-road motorcycles. Both companies sell plastic sets for most popular Honda, Yamaha, Kawasaki, Suzuki, KTM, and Husqvarna models, and both are considered solid OEM-replacement options. The real differences riders run into are fit precision on specific models, how many color options are offered per kit, and price — not one brand being flatly "better" than the other.

If you're shopping MotoKong's motorcycle plastics selection and trying to decide between a UFO kit and an Acerbis kit for your bike, this guide breaks down what each brand is known for, what riders report in real-world use, and how to pick the right one for your model.

Where Do UFO and Acerbis Plastics Come From?

Acerbis was founded in 1973 by Franco Acerbis in Albino, in the Bergamo province of Italy. The company's first products were motocross fenders, and it later expanded into full thermoplastic body kits, boots, and other riding gear, making it one of the oldest names in off-road plastics.

UFO Plast came along a few years later, founded in 1977 in Tuscany, Italy. The company built its reputation specifically around off-road motorcycle plastics and accessories, and it has stayed closely tied to motocross racing ever since — UFO is currently the official plastics sponsor of the SMX World Championship and Pro Motocross series.

Both companies are still Italian-made, both focus heavily on motocross and off-road applications rather than street-bike fairings, and both sell complete body kits as well as individual replacement pieces, so you're not locked into buying a whole set if you only cracked one fender.

What Do Riders Actually Say About Fit and Durability?

Search any motocross forum and you'll find riders firmly in both camps, which is usually a sign that neither brand is dropping the ball. In threads on the Vital MX forums, several riders said UFO consistently nailed the fit on their bikes and called out the value — one rider mentioned paying under $90 for a UFO kit bought direct, versus well over $125 for the Acerbis equivalent at the time. Other riders reported the opposite experience: one said Acerbis fit their Husqvarna "better than the OEM stuff," and another called Acerbis durability "beyond seasonal."

A few common threads show up regardless of brand preference. Color matching is occasionally reported as slightly off from the product photos, a bolt hole sometimes needs a light touch with a round file or drill to seat perfectly, and plenty of riders describe both brands as "basically the same as OEM" once the kit is actually mounted. If you've bought either brand before and had a mixed experience, you're not alone — small running changes between model years are a common culprit, not necessarily the plastic itself. Our guide on why a part might not fit as ordered walks through the usual reasons.

Picking the Right Plastics Kit for Your Bike

Whichever brand you lean toward, getting the fit right starts with matching your exact model and year. Plastics are one of the most model-specific parts on a dirt bike, and a kit made for an early version of a model year run won't always bolt straight onto a later one, even within the same generation — always check the listed fitment against your bike's year and model before ordering.

A few examples of what's in stock to give you a sense of what each brand offers: if you ride an older Honda CR, UFO's replacement body kit covers the full set in factory-style red and white. On the Acerbis side, Husqvarna owners can find a full replacement body kit in black for a clean, non-OEM look.

Full Kit or Piece by Piece?

If your bike went down hard and you cracked a fender, shroud, and side panel in the same spill, a full kit is usually the better value — you get matched colors across every piece and typically pay less per panel than buying each one separately. If you only need to replace one cracked or faded piece and the rest of your plastics are still in good shape, buying that single piece (from either brand) keeps the rest of your bike's look consistent without paying for parts you don't need.

One more practical note: colors fade at different rates depending on sun exposure and riding conditions, so a single new piece next to older, sun-faded plastic may not match perfectly even within the same brand and color code. That's normal, not a defect, and it's one more reason full-kit buyers tend to be happier with how uniform their bike looks after a refresh.

Is UFO or Acerbis better quality?

Neither brand is objectively better across the board. Riders report excellent fit and durability from both, and forum feedback is split roughly down the middle. The more useful question is which brand makes a kit for your exact model, year, and color combination, since availability varies bike to bike.

Will aftermarket plastics fit as well as OEM plastics?

Most riders describe a good aftermarket fit from either brand as very close to OEM, sometimes needing a minor bolt-hole adjustment. If your bike has had a running change mid-model-year, double-check the fitment notes before ordering either brand.

Can I mix UFO and Acerbis pieces on the same bike?

Yes, many riders do this, especially when replacing just one damaged piece. Just know that exact shades can vary slightly between brands and even between production runs of the same brand, so a perfect color match isn't guaranteed.

Do UFO and Acerbis plastics come pre-drilled for OEM hardware?

Generally yes, both brands design their kits to use your bike's factory mounting hardware. Some riders report an occasional bolt hole needing to be slightly enlarged, which is common with aftermarket plastics from any brand, not specific to either company.

Do these brands make plastics for street motorcycles too?

Both brands are best known for off-road and motocross applications. If you're looking for street-bike fairings or body kits, check MotoKong's full fairings, plastics & body kits category for what's currently available for your model.

How do I know which kit fits my specific bike?

Check the fitment details listed on each product against your bike's exact year and model before ordering. If you're not sure, reach out to MotoKong with your bike's year, make, and model to confirm before you buy.
