Product Description

ACF-50 for Motorcycles

What is it?

ACF-50 (Anti-Corrosion Formula) was originally designed to protect aircraft from existing and new corrosion and is now available to motorcyclists. Aviation products have to meet rigorously high standards and ACF-50 not only meets these but has been awarded Aviation approvals - MIL-SPEC 81309 types II and III which means it is 'approved for ferrous and non-ferrous metals, electrical systems and electronic components'. The US Navy carried out tests using ACF-50 on the jets on their Aircraft Carriers. They found that ACF-50 so significantly reduced the corrosion they had previously experienced they now use ACF-50 all the time!

It works perfectly in that type of harsh environment so imagine how well it's going to protect your bike!

When applied ACF-50 forms an 'Active' ultra-thin clear film that will kill any existing corrosion cells and will protect your bike against new corrosion forming. On areas such as switches or under the tank and seat, one application will last up to 12 months. Other more exposed areas will need topping up more regularly. ACF-50 has the ability to 'chemically neutralise road salt' and water will bead on contact and literally bounce off. Ideal for the bike that is used all year round in all weathers, a superb service spray as ACF-50 is also a lubricant and penetrant (without loosening structural attachments) and if you put your bike away for the winter, applying ACF-50 will ensure that moisture will not be allowed to cause any damage! Untreated moisture will creep into cracks and will not freely evaporate - ACF-50 actively ejects moisture from these areas.

The Facts

  • Kills existing corrosion and prevents new
  • 'ACTIVE' for up to 12 months
  • Excellent lubricant and penetrant
  • Approved for use on electrics and engines
  • Easily applied non-drying, ultra thin, clear film
  • Very economical
  • Contains no wax, silicon, Teflon or water

How to Use

ACF-50 is 95% product, hence virtually no propellant. Keep the tin in a warm environment, shake very well before use and remember a little ACF-50 goes a long way, so keep a rag handy to soak up any excess - then use the rag to help spread the product. ACF-50 has strong capillary action so will creep into all the areas that moisture can, 'actively' pushing out moisture and replacing it with protection. Go cautiously when applying to callipers to ENSURE YOU KEEP IT OFF THE BRAKES.

Use ACF-50 anywhere, except the brakes, on your bike including the engine and exhaust (will smoke on first start and burn off down pipes but still slows down corrosion process). Safe on paintwork, most rubbers and brings up black plastic trim a treat. ACF-50 contains no water and is approved for electrics so spray directly into electrical joints and components where it will prevent corrosion induced failures and high resistance joints. Works well at stopping dirt, mud and salt from sticking. You can come back from a winter ride with the bike 'white with salt' - a quick wash off and it's gone with the bike still protected.

Areas not in direct contact with the elements ie tank/seat areas, electrics require treating approx once a year. Other exposed areas re-apply as necessary. You can tell the product is still 'Active; as water will bead on contact...having no water content and not being water soluble ACF-50 only dissipates by being 'sacrificial' whilst stopping existing or new corrosion so just re-treat as required.

Remember, ACF-50 protects jets on US aircraft carriers! If it works for these jets in these conditions, think how well it's going to work for your bike!

What People are Saying about ACF-50

I ride a bike all year round and I have been using ACF-50 for about 18 months. My Hayabusa has not corroded and it is great on the wheels where all the road salt and grit ends up. All the alloy is corrosion free, and I will be using it straight away on my ZZR 1400 when I pick it up next week

Highly recommended

I 'discovered' ACF-50 last winter and was hoping that it was as good as the reports said. In November I gave the bike a thorough cleaning, took as many of the removable parts as possible off my BMW F800ST and gave it a good spraying. Snowy conditions aside, I commuted 300 miles per week and didn't wash the bike until the end of March. The bike was almost black. Guess what? Having removed all the layers of grime - no corrosion, the bike cleaned up like new. ACF-50 is amazing, all that's required is a strong nerve and a little faith!


“My mate ran this on his Fazer coated the engine, etc. Rode all winter in the wet, kept outside under a cover. Washed it off at the end of the winter, bike looked mint! Mine looked worse with only a handful of winter dry miles and garaged! Great stuff

I've used both: FS365 the winter before last and ACF50 this winter just gone. I prefer ACF50. "

Really good stuff! does what it says on the tin, would highly recommend this to anyone, bike's been fully protected with acf50 for two and a half years now with absolutely NO new corrosion or rust! well worth the money, wish i'd discovered it sooner!

The big disadvantage to FS365 is you have to keep re-applying it, especially after a wet ride. You get home, it's teeming down with rain and you have to spend a minute or two out there spraying the engine, fork legs, etc before you can cover it or roll it into the garage (assuming there's not enough room in your garage to do this).

With ACF50 you apply a nice coating and ... leave it. You can spray extra on occasionally, as you see fit. The engine looks absolutely filthy after a while, but that means its doing its job. I only cleaned the engine once or twice last winter, which meant reapplying the ACF afterwards, and it has survived fine. For the fork legs, I would clean and reapply every time I washed the bike.

It doesn't take much ACF50 to get a good coating so a can should last several winters, which makes it better value than FS365 in my opinion.”

"I was sceptical at first but I researched it on the net - It's used by the US Airforce on their aircraft carriers, used by boeing and other manufacturers. I have used it since September and apart from having to reapply it to my downpipes it has lasted through many washes and many winter rideouts, no furring on nuts and bolts or whatever. When you ride a 9 grand superbike it's worth its weight in gold. I have just replaced my tin having used it on my other vehicles. I paid 12 quid-ish. Despite the cold weather I have used my bike far more than before because I'm less anxious about road salt rotting my pride and joy!"
