Hi there again,
Don from Ricor/vibranator company indicated that this is the right device for a Tenere xt660z with BarkBusters hand guards:

I will keep you posted about the installation and final result.
He also sent me a quick pdf manual about how to fit the vibranator with and without handguards. Send a PM if you are interested and I can send it by email.
Cheers
