As all Sportsbikes do use chains to drive the Wheel, but most of them do have way too heavy Drivechains, mostly 530 - I thought it maybe a good Idea to offer here those real Quality 520 "lightweight" drive Chains which I use since 20 years.
Those Drivechains from DID or EK can last " a Lifetime" if serviced correctly.
Maintenance: Long Time ago I got a hint from an AFAM-Employee, he asked :" What you use for servicing your Drivechain ?" , I replied " a usual chain-Oil ", then he gave me hint ( an Oil not really designed to be used for servicing a drivechain ) , he said :" use Bel-Ray 6in1 " .
I did it, and never regret it.
Now this Lubricant is my recommendation - to you.
