If you're hunting for a fresh set of 2003 kawasaki 636 fairings, you already know how much of a legend this bike is. The "B1H" model, as the enthusiasts call it, was the bike that really put Kawasaki back on the map in the early 2000s. It had that aggressive look, the weirdly specific 636cc engine that gave it a bit more grunt than the competition, and, of course, those sharp, angular body lines. But let's be real—twenty years is a long time for plastic to stay in one piece.
Whether you had a low-side at the track, a tip-over in the driveway, or you're just tired of looking at faded, scratched-up paint, replacing your fairings is one of those projects that can totally transform the bike. It takes it from looking like a neglected "stunt bike" back to a showroom-quality head-turner.
Why the 2003 Fairings Are Special
The 2003 and 2004 models shared the same body style, which was a huge departure from the rounded ZX-6Rs of the late 90s. This was the era of the "mean" Kawasaki. The fairings on this bike aren't just for show; they're actually pretty functional with the ram-air intake right in the nose.
When you're looking for 2003 kawasaki 636 fairings, you'll notice that the front cowl is one of the most distinctive parts. It's got that sharp "beak" look and houses the dual headlights. If those tabs are broken—which they usually are on older bikes—your headlights will rattle like crazy. That's why a lot of guys just opt for a full new kit rather than trying to patch up the old OEM stuff with zip ties and epoxy.
OEM vs. Aftermarket: The Great Debate
Back in the day, if you wanted new plastics, you went to the Kawasaki dealer and paid a fortune. Today? Good luck even finding a full set of OEM (Original Equipment Manufacturer) fairings for a 2003 model. Even if you find a "new old stock" set, the price would probably be more than the bike is worth.
That's where aftermarket kits come in. Most of what you see online nowadays are Chinese-made fairing kits. Now, I know what you're thinking—"Are they actually going to fit?"
The short answer is: mostly yes, but with a bit of "massaging." The quality of aftermarket 2003 kawasaki 636 fairings has actually gotten way better over the last decade. They mostly use injection-molded ABS plastic now, which is the same process Kawasaki used originally. It's way more flexible and durable than the old compression-molded stuff that would crack the second you tried to stretch it over a bolt hole.
Injection Molded vs. Compression Molded
This is the most important thing to look for when you're shopping.
- Injection Molded: These are made using a high-pressure mold. The fitment is usually about 95% to 98% perfect. The bolt holes are usually pre-drilled, and the plastic is consistent in thickness. If you can afford the extra fifty or a hundred bucks, always go for injection molded.
- Compression Molded: These are cheaper because the manufacturing process is simpler. They're basically pressed into a mold. The problem? The holes often don't line up, and you might have to drill your own. They also tend to be more brittle. Honestly, for a bike as nice as the 636, it's not worth the headache.
Picking a Color Scheme
This is the fun part. Since you're replacing the whole kit, you aren't stuck with the original color your bike came with.
- Classic Kawasaki Green: You can't go wrong here. It's iconic. It makes the 636 look like it just rolled off the production line in 2003.
- The "Monster" Look: This was huge in the mid-2000s. A lot of kits come with the black and green claw graphics. It's a bit dated for some, but it still looks aggressive.
- Matte Black or "Stealth": If your frame is in good shape, a matte black set of 2003 kawasaki 636 fairings looks mean. It hides the lines of the bike a bit, but it gives it a modern "streetfighter" vibe.
- Race Replica Kits: You can find Movistar, West, or even old-school KRT (Kawasaki Racing Team) designs.
One thing to keep in mind: if you buy a kit with graphics, check if the decals are under the clear coat. Most decent aftermarket kits clear-coat over the stickers so they don't peel off the first time you wash the bike or get some gas on them.
The Installation Process (And the Headaches)
Installing new 2003 kawasaki 636 fairings isn't exactly rocket science, but it does require a fair amount of patience and maybe a six-pack of your favorite beverage.
First, do yourself a favor and buy a new bolt kit. Do not—I repeat, do not—try to reuse the old, rusted, mismatched bolts that are currently holding your bike together. A fresh hardware kit with the right rubber well-nuts and plastic washers will make the job 100% easier. It also makes the finished product look way cleaner.
When you're putting the new plastics on, don't tighten everything down right away. Start all the bolts loosely first. This gives the fairings room to wiggle so you can get the tabs lined up. If you tighten the bottom fairing before you've even started the mid-section, you're going to be fighting the plastic the whole time.
Also, be careful with the ram-air tubes. On the 2003 636, these can be a bit finicky to align with the front nose fairing. If they aren't seated right, your intake won't be as efficient, and it'll look "off" from the front.
A Note on Heat Shields
One thing people often forget when buying aftermarket 2003 kawasaki 636 fairings is the heat shielding. The exhaust on these bikes runs pretty close to the lower fairings. Most aftermarket kits come with some adhesive silver heat foil. Use it. If you don't, there's a solid chance you'll end up with warped or melted plastic after your first long ride. Pay extra attention to the areas near the headers and the mid-pipe.
Maintaining Your New Look
Once you've got the bike looking brand new, you'll want to keep it that way. Aftermarket paint isn't always as "hard" as factory paint. I'd recommend giving the new fairings a good wax or even a ceramic coating before you head out on the road. It makes bugs and road grime way easier to wipe off later.
Also, be mindful of how you store the bike. Constant sun exposure can fade aftermarket plastics faster than OEM ones. If you can't keep it in a garage, a decent bike cover is a cheap way to protect your investment.
Final Thoughts
The 2003 636 is a special machine. It represents a specific era of raw, analog sportbikes that didn't rely on traction control or wheelie control to make you feel fast. It's a bike that deserves to look good.
Updating your 2003 kawasaki 636 fairings is probably the best bang-for-your-buck upgrade you can do. It doesn't just make the bike look better for you; it drastically increases the resale value if you ever decide to part with it. Plus, there's just something incredibly satisfying about standing back and looking at a "new" bike that you put together yourself.
Just remember: take your time, get the injection-molded stuff, and don't forget the heat shields. Your 636 will thank you for it by looking like a total beast on your next Sunday ride.
