maybe it was dragging?
Make sure he does not put DOT 5 in!...after 2200 KM of riding. I this common? Did the brake fluid started to boil??
I was told, that this problem is due to the heat here in Thailand. A local Ducati mechanic told me, that he will change the brake fluid to DOT 5 (!!!) during the next service. I do know, that this fluid can handle higher temperatures, but I will have to watch out, it should be DOT 5.1. if any.
Asolutely - DOT 5 is NOT compatible with the Scramblers ABS system!!Make sure he does not put DOT 5 in!
