If you're looking to swap out your old, cracked fenders for a 2005 trx450r plastic kit, you probably already know how much of a difference a fresh set of plastics can make to the overall vibe of your machine. There is just something about a clean, shiny quad that makes it feel like it's brand new again, even if it's been through the ringer on the trails or the track for nearly two decades. Let's be honest, the 2005 TRX450R is a legendary machine—the "kicker" year that many Honda purists still swear by—but even the most bulletproof engine can't hide the fact that twenty-year-old plastic starts to look a bit tired.
Whether your current fenders are held together by zip ties and hope, or they're just hopelessly faded from years of sitting in the sun, upgrading your plastics is one of the most satisfying projects you can take on. It's not just about looks, either. Brittle plastic can snap at the worst possible moment, and nobody wants a sharp piece of fender digging into their leg during a hard landing.
Why the 2005 Model Still Deserves the Best
The 2005 Honda TRX450R holds a special place in the hearts of ATV riders. It was that sweet spot in design where the quad was light, aggressive, and had that raw power that people still crave. Because these bikes are so well-built, there are still tons of them out there tearing up dunes and woods. But because they are used the way Honda intended, they usually show their age on the outside.
Finding a 2005 trx450r plastic kit today is actually easier than you might think, which is a testament to how popular this quad still is. You don't have to settle for scuffed-up OEM parts from a salvage yard. Aftermarket companies have stepped up big time, offering kits that often fit better and hold up to abuse better than the original stuff did back in the day. Plus, you get the chance to move away from the standard red if you're feeling like a change of pace.
Picking the Right Color and Style
When you start shopping for a kit, the first big decision is obviously the color. You can't ever go wrong with the classic Honda Red. It's iconic, it looks fast standing still, and it just feels right on a TRX. However, since you're replacing everything anyway, why not get a little creative?
White plastics offer a super clean, "factory" look that makes the frame and engine pop, especially if you've got a black or red frame. The downside? They show every bit of Georgia clay or muddy water if you don't scrub them down immediately. Then there's black. Black looks mean and stealthy, but man, it shows every single "roost" scratch and swirl mark within the first five minutes of riding.
Some people even go for more "out there" colors like fighting red or orange, or even a two-tone setup. A common move is to run a different color for the hood or the tank cover to break things up. Whatever you choose, make sure it's a color you're going to be happy with for a few years, because a good quality kit isn't exactly pocket change.
Compatibility and Fitment Realities
One thing you've got to keep in mind is that the 2004 and 2005 models are essentially twins when it comes to the bodywork. If you see a kit listed for an '04, it's almost certainly going to work for your '05. However, things changed a bit when the electric start (ER) models came out in 2006. While some parts might look similar, the mounting points and the way the fenders sit over the engine and battery box can be different.
When you're looking for a 2005 trx450r plastic kit, always double-check that it's specifically designed for the kick-start generation. Most reputable brands like Maier or UFO are very clear about this. You don't want to be halfway through an install only to realize the tank cover doesn't line up because the kit was actually meant for a later model year.
What's Actually Included in a Kit?
Most full kits are going to give you the essentials: the front fenders and the rear fenders. Some "complete" kits go a step further and include the tank cover and the hood. If you're doing a total overhaul, I'd highly recommend getting the kit that includes the hood and tank cover. There's nothing worse than putting on beautiful new front and rear fenders only to have your old, scratched-up tank cover sitting right in the middle like a sore thumb.
If you're looking to save a few bucks, you can sometimes find "race cut" fenders. These have the front "wings" trimmed back. It's a popular look for MX riders because it gives you a better view of your front tires and saves a tiny bit of weight, but if you ride in the mud, be prepared to get absolutely covered. Full fenders are definitely the way to go if you do a lot of trail riding or just don't want to eat dirt all day.
The Installation Process (and Staying Sane)
Installing a new 2005 trx450r plastic kit is a job you can definitely do in your garage on a Saturday afternoon, but it does require some patience. It's not just a matter of popping out a few clips. You're going to be dealing with those annoying plastic push-pins, various bolts, and the rubber grommets that keep everything from vibrating to pieces.
Pro tip: don't throw away your old hardware until the new kit is completely on. You'd be surprised how often a new kit is missing one specific washer or bolt, and you'll be glad you kept the old ones. Also, if you're working in a cold garage, the plastic can be a bit stiff. If you're having trouble getting a hole to line up with a bracket, a little bit of heat from a hairdryer (don't go crazy with a heat gun) can make the plastic just pliable enough to get that bolt started.
Another thing to watch out for is the heat shielding. Your exhaust gets incredibly hot, and the rear fender sits right above it. Most kits don't come with the heat-reflective tape pre-installed. You'll want to peel the old stuff off your old fenders if it's still good, or better yet, buy a new roll of adhesive heat shield. If you skip this step, you'll end up with a melted, warped spot on your brand-new rear plastics within the first hour of riding.
Graphics: The Finishing Touch
Once the new plastics are on, the quad is going to look a bit naked. A 2005 trx450r plastic kit is basically a blank canvas. This is the perfect time to pick out a graphics kit. Whether you want to go for a "replica" look of the old racing teams or something totally custom, graphics do more than just look cool—they actually provide a layer of protection against scratches and "branch rash."
Applying graphics is an art form in itself. Use a little bit of soapy water in a spray bottle so you can slide the sticker around until it's perfectly centered. Then, use a squeegee to get the water out from under it. It's a slow process, but it makes the difference between a quad that looks professional and one that looks like a middle-schooler's notebook.
Keeping the Shine Alive
After you've spent the time and money to get your TRX looking mint, you're going to want to keep it that way. The secret weapon for anyone with an ATV is silicone spray (like SC1, often called "new bike in a bottle"). After you wash your quad and it's dry, spray a light coat on the plastics and let it sit. It gives it a deep shine and, more importantly, it creates a slippery surface that mud doesn't like to stick to. Next time you go riding, the dirt will practically fall off when you hit it with the hose.
Just be careful not to get that stuff on your seat or your footpegs. Seriously, you'll be sliding off the bike the first time you hit a bump. Keep it on the fenders where it belongs!
Wrapping It Up
At the end of the day, a 2005 trx450r plastic kit is one of the best investments you can make for an older quad. It protects the internals, keeps you safe from debris, and honestly, it just feels good to pull up to the staging area with a machine that looks like it's cared for. These Hondas were built to last a lifetime, and with a fresh set of skins, yours will be looking good for another twenty years of riding. So, grab some tools, maybe a buddy to help hold the fenders in place, and give that old kicker the makeover it deserves.
