A simple product made complicated.

First thing to note is that most established companies such as Renold, iwis and Sedis do not want
to be involved to the low volume motorcycle business. Renold never really produced a "motorcycle"
chain they just made superb industrial chain.

Old Brit bikes and indeed Italian used chain because it was readily available and is the most efficient
way to transmit power.

As to the Diamond, they will also not mention motorcycle but they do have many chains is the range.

The different materials all refer basically to industry with for example stainless and afore mentioned
chromised steel. Stainless is a no no on motorcycles as it is unhardened and chromised, apart from
iwis where it is standard, is used mainly for cam drives, in both cases the cost rises.

There are only really 2 standards ASA (American Standard) and BS (British Standard) there is only one
size, 10B-1 and asa50, that have the same gearing dimensions. But the ASA is wider and can cause
problems when used on some Brit bikes. Importantly these standards DIN 8187 (BS) and DIN8188 (ASA)
are not a measure of quality as such, but a dimension standardization. This means that a 10B-1 connecting
link will fit across all manufacturers using this standard.

As for lubefree or maintenance free chains apart from O ring chains these should again not be used on
motorcycles. Most have a sintered bush and as of yet nobody has found out how to harden one of these.

Going back to diamond it is interesting to put motorcycle in the search feature.

Here is their "Powersports" products page, which mentions motorcycles and ATV's. http://www.diamondchain.com/power-sport ... p5HLU32b4g

All these mentioned are base on Jap chains and dimensions. Brit bikes need the
British Standard dimensions looking through the range they dont appear to list
chains to DIN8187.

Please dont get me started on heavy duty

A good friend tried out the Diamond chain on his Vincent quite some years ago. This was before the advent of sealed chain, so it has been around for a long time.
From the ad hype for the Diamond, he believed he had found a chain that would last for eons.

One three thousand mile trip and multiple adjustments later it was time for a new chain, silly thing didn't even last as long as his regular chains, whatever they were back then.

I must be rude about other manufacturers chains but all I can say is that there is
a load of crap out there.
