I recently installed the Yoshimura Oil Filler Cap Type-FB on my Kawasaki ZX-4R, and here’s my review:About quality and textureThe quality of the Yoshimura Oil Filler Cap is excellent. It’s made from durable materials, and the finish is smooth with a nice Yoshimura logo engraved on it. It looks high-end and adds a bit of a premium feel to the engine area. It doesnt come with a new O-ring though.About the feeling of useThe cap feels solid and well-made. It fits perfectly and securely, so I have no worries about leaks. Plus, it comes pre-drilled for safety wire, which is a great feature if you’re using it for track days or just want extra security.Products to buy togetherI would recommend pairing this with other Yoshimura parts, like their bar ends or frame sliders, to keep the look consistent across your bike. It’s a nice touch to have matching pieces.Difficulty of installationThe installation was super easy. You’ll need a 14mm socket to tighten it properly, and it only took me a couple of minutes to install. No special tools needed, and it fit perfectly with my ZX-4R.Cost performance and comparison with other productsIt’s a bit more expensive than basic oil caps, but the quality and design are well worth the price. Compared to cheaper options, the Yoshimura cap feels more solid and gives the bike a cleaner, custom look.About shipping and packagingShipping was fast, and the packaging was great. The oil cap came in a small, well-protected box, so it arrived in perfect condition without any scratches or dents.Any concerns, cautions, or advice when purchasingMy only advice is to make sure you have the 14mm socket ready for installation. Also, the pre-drilled hole for safety wire is a great bonus if you’re into track riding. Overall, it’s a small but excellent upgrade for the ZX-4R, both in terms of function and appearance. I’m really happy with it!
Ce bouchon de remplissage d'huile de marque Yoshimura est très bien fini. Il apporte un côié vraiement plus classe que le bouchon simple en plastique Honda. Cela rend très bien avec un carter noir. A noter qu'il faut bien conserver le bouchon d'origine pour faire vos niveaux d'huile car celui ci n'est qu'un simple bouchon. Je le reocmmande et merci à Webike pour leur service!----------------------------------------------------------This Yoshimura brand oil filler cap is very well finished. It brings a really classier look than the simple Honda plastic cap. It looks very good with a black crankcase. Note that you must keep the original cap to do your oil levels because this one is only a simple cap. I recommend it and thank you to Webike for their service!Powered by Google TranslatorView Detail

About quality and textureGreat material from Yoshimura once again. Non plastic like the OEM one. Made of aluminium coloured. My is blue in color.About the feeling of useLooks great on the bike. Not my first time buying. I bought for my Suzuki Katana too.Products to buy togetherI bought the other engine cover protectors just to much the yoshimura look.Difficulty of installationUsing the same rubber gasket as the oem one. No issue installing it.Cost performance and comparison with other productsIt's a bit more pricey. But nothing beats yoshimura itemsAbout shipping and packagingShipping is cheap as item is small in size.Any concerns, cautions, or advice when purchasingMaybe when removing and installing try to use a plastic to cover the item so that it won't scratch or decolonize it.View Detail
About quality and textureThe bracket is solid and well made. The metal is thick enough to feel sturdy, and the finish is clean with no sharp edges or burrs. The mounting holes are well drilled and the surfaces are smooth.About the feeling of useOnce installed, the horn holds firmly in place. I like that it’s possible to adjust the position so the wires can be better hidden behind the frame. That makes the setup look cleaner and reduces the risk of snagging the wires.Products to buy togetherI recommend grabbing a P-clip to secure the horn wiring to the original horn location for a cleaner look.Difficulty of installationThe install was straightforward, but there is one catch: the instructions show a different bracket for the ABS sensor wire, so you must fit the horn bracket after securing the ABS sensor wire bracket (not before). I used a P-clip to secure the horn wire at the original horn mounting point, which worked nicely. Take your time positioning things and test fit before tightening fully.Cost performance and comparison with other productsThis bracket is modestly priced compared to premium alternatives. It doesn’t have a fancy design, but it does its job well. In my view, for the cost you’re getting solid value, especially given the adjustability and decent build quality.About shipping and packagingIt arrived in a plain but sturdy box. The bracket was wrapped so it didn’t get scratched in transit, and all the hardware was included and organized. Shipping was timely and no parts were missing.Any concerns, cautions, or advice when purchasingMake sure you install the ABS sensor wire bracket first, before mounting this horn bracket, because the instructions assume a different bracket layout.Be careful to route the wires so they don’t rub on edges or move too freely. Using a P-clip or cable tie at the original horn mounting point helps.Check clearances once mounted, especially near forks or other moving parts.After a few rides, re-check all bolts in case vibration causes slight loosening.View Detail
About quality and textureThe machining is top notch — edges are crisp, surfaces are clean, and there are no visible flaws or rough spots. The finish looks great: anodized black and silver parts blend nicely with the bike’s overall aesthetic, and the hardware all matches. The texture gives just enough grip underfoot without feeling too abrasive.About the feeling of useOn the road, the rearsets feel precise and solid. I especially like how they integrated the return spring into the rear brake pedal — that’s a smart touch. The brake lever returns cleanly and doesn’t flop around. The shift action is also good with reduced slop or play, and shifting feels more direct than with the stock rearsets.Products to buy togetherTo make the most of these rearsets, I’d pair them with new stainless (or titanium) bolts and locknuts to match the high end of the parts. Also, a good quality thread-locker (medium strength) is a must. If you’re upgrading foot controls, matching rearsets with a shorter shift rod or linkage can help optimize ergonomics. And if you use heel guards, make sure they line up with the rearsets’ mounting points.Difficulty of installationInstallation took me a couple of hours, largely because I was being careful. You’ll need basic hand tools (metric sockets, spanners, Allen keys). Pay attention to torque specs and make sure the levers move freely without interference.Cost performance and comparison with other productsThese Over Racing rearsets are certainly more expensive than entry-level generic rearsets, but you’re paying for better fit, finish, and engineering. Compared to other premium brands I’ve tried, they feel more tailored to the bike (less need for adjustments). The weight savings of around 0.5 kg off the stock setup helps a bit (especially high on the bike) and justifies the upgrade for me. For the quality and features, I think you’re getting good value among high-end rearsets.About shipping and packagingThey arrived in a sturdy, well-packed box with foam inserts so none of the parts were scratched or damaged. All the components were individually wrapped, and nothing was missing. Shipping was prompt (within expected timeframe), and the tracking updates were reliable.Any concerns, cautions, or advice when purchasingDouble check that the rearsets are exactly for the ZX-4RR (many rearsets cover wide model ranges, and slight differences can affect fit).Use medium thread-locker on critical bolts (especially pivot bolts) to prevent loosening from vibration.After install, re-inspect all hardware after your first few rides (vibration can settle things).View Detail
About quality and textureThe machining and finish are excellent, just what you’d expect from Over Racing. The anodizing is clean and even, and the overall feel is very solid. It doesn’t really save any weight compared to stock, but the quality and rigidity are a clear step up.About the feeling of useOnce installed, the front end feels more planted and precise. Steering feedback is sharper, and the bike feels a little more rigid under braking. It’s a subtle difference, but definitely noticeable.Products to buy togetherIt pairs well with upgraded clip-ons or bar ends, since you already have everything apart. A steering stem nut from Over Racing or similar would also complete the look.Difficulty of installationInstallation isn’t overly complicated if you’re comfortable with tools, but it does require removing the stock top bridge and carefully re-torquing everything to spec. Having a torque wrench is a must. You will also need to remove the shear bolts! I used the dremel method by cutting a slot and using a flat head screw driver to remove them.Cost performance and comparison with other productsIt’s not a cheap upgrade, especially since it doesn’t really save weight, but the finish and rigidity justify the price if you’re after performance feel and aesthetics. Compared to other aftermarket bridges, the quality of machining stands out.About shipping and packagingThe product arrived well-packaged with plenty of protection. No scratches or damage on arrival, and the parts were individually wrapped.Any concerns, cautions, or advice when purchasingDon’t expect dramatic weight savings—it’s about rigidity and quality feel rather than shedding grams. Make sure you torque everything correctly during installation, and be prepared to re-align your controls afterward.View Detail
About quality and textureThe Eazi-Grip Centre Tank Pad for my Kawasaki Ninja ZX-4RR feels premium right out of the package. The material is thick, flexible, and has a high-quality finish that blends perfectly with the bike’s tank. It doesn’t look cheap or like an afterthought.About the feeling of useOnce installed, it provides excellent grip and prevents my jacket zipper from scratching the tank. It’s subtle in appearance but makes a noticeable difference in comfort and control when riding.Products to buy togetherBest paired with Eazi-Grip tank grips for the sides to get full tank protection and better knee grip.Difficulty of installationInstallation is very easy thanks to the simple instructions provided. Just clean the tank, align, and stick—took me less than 10 minutes.Cost performance and comparison with other productsThe price is fair for the quality. I’ve seen cheaper tank pads, but they often have poor adhesive or fade quickly. This one feels built to last, so it’s worth the extra cost.About shipping and packagingArrived quickly and well-packed, with a protective film on the pad to prevent scratches before installation.Any concerns, cautions, or advice when purchasingMake sure the tank is completely clean and free of wax before installation for the best adhesion. Also, check your positioning before sticking it down—once it’s on, it’s hard to adjust.View Detail
About quality and textureThe quality of the Zero Gravity Corsa screen is decent, but it’s not quite on the same level as the OEM screen. The material feels a bit thinner and not as refined around the edges, though the overall shape and finish are still good enough for everyday use.About the feeling of useOnce installed, the Corsa screen made a noticeable difference in wind protection. At higher speeds, especially on the freeway or track, I felt much less wind hitting my chest and helmet. It gives the bike a more aggressive look too, which I really like.Products to buy togetherI added the kawasaki oem sticker.Difficulty of installationInstallation was straightforward. It’s just a few screws to swap the OEM screen out, and everything lined up without issues. Took me about 15 minutes with basic tools.Cost performance and comparison with other productsIn terms of value, it’s reasonably priced. It’s cheaper than some of the high-end options like MRA or Puig, but you do get what you pay for — less refinement, but solid performance. If you’re after better wind deflection without breaking the bank, this is a good choice.About shipping and packagingShipping was quick and the packaging was secure. The screen came wrapped well with no scratches or damage.Any concerns, cautions, or advice when purchasingIf you’re really picky about fit and finish, just be aware that this won’t match OEM quality exactly. Also, double-check that you’re ordering the Corsa version — there are different shapes (Double Bubble, Sport Touring, etc.), and they vary a lot in looks and performance.View Detail
