Some good motorcycle chain lube.The bottle is small enough to throw in my tool bag and allows me to maintain chain while on the road.Remember you are supposed to lube every 500 miles. You may have to do more frequently if doing a lot of rain riding.Compared to other chain lubes this stuff is pretty clean. It leaves a bluish tint instead of black gunky mess. I think compared to most products it's superior in the mess category.As a lube it lubes my chain, I have no means of testing it's effectiveness compared to other products except other than the fact that my chain is lubed.I wanted the lube that covers the chain in a firm white coat and this is it. Not sure about how good a lubricant it actually is but I have to rely on BelRay's name for that. I wish it came in a larger can. Good overall process.It had a bad straw it was cracked or I would have given you 5 starsI really like this chain lube. It isn't really tacky and messy as many others. Despite not being very messy it still holds to the chain very well. My only complaint is the white residue it leaves which remains there. It does provide a handy indication though that you should reapply if your chain is missing some whiter patches.Expensive for the size of bottle. If you're lucky maybe two uses.. Makes your chain look white you have to put an even coat on your chain beware of splash on rims.I bought this because it was in a small can and I could easily carry it with me on an upcoming 2500 mile trip. Well, I made the trip and used it along the way and it's honestly the worst chain lube I have ever used , Its difficult to get on evenly and just coats the chain with a white substance rather than penetrating it and lubricating it. The spray nozzle is also very messy and hard to get the lube where you need it, so you end up lubing your wheels if your not super careful. in 30 years of motorcycling, this is the first Bel Ray product I had a problem with, but I wanted to let others know so they could save their money.... stick with Maxima or Motul, you won't be disappointedI purchased this size bottle to take with me on my longer rides. It's bigger than expected but it's still smaller than regular size.Works great as a chain lube but it turns the chain a whitish color. If you don't mind that it works great
