Believe me Bill it wasn't really on purpose when I started not lubing my chain. The old Triumphs I had shot breather oil on it so it never needed to be lubed. So when I got this bike I just never really thought about it and lubed it a couple times. I really don't think it's worth it to lube it but I only have had this one stock chain and sprockets so I have no idea if anyone else would get the same results under different riding conditions. I rarely ride in bad weather and park my bike for the winter for the most part, It doesn't get as hot or cold here as other parts of the country, it isn't sandy here and so on. I can think of tons of variables that may play into the results. Could be I just got a really good set from the factory, who knows? Could be they tell you to lube the chain for liability reasons. I know with a std chain you should lube them since there is no seal to keep the dirt out or lube in. I was going to replace my chain and sprockets with a std. DID 530 and Honda sprockets but I think I may buy another OEM set from Triumph since these have worn so well.

I learned all I need to know about life by killing smart people and eating their brains.
