Ok, DAS erklärt ( mir ) natürlich auch den bei einigen China Varianten mitgelieferten Ring und die grade gefundene Bewertung des China Produkts:
"You have to remove the entire pulley system to put the mount behind it. Costs 250 USD at Harley Davidson to do it for you.
If you do it yourself it is very dangerous as you need to use a special locking tool to lock the nut back into the Pulley. HD service manual warns you to NEVER use the same unlocked nut.
This is a major part of your bike. Dont buy unless you want to spend 350+ USD on putting something like this on. Or do it cheap and risk your bike falling apart!"
