I've not made much mileage with the BDS Carrier. What I can say at this stage : much better feeling in response to the acceleration, and while the previous sprocket carrier required changes of silent blocks after 3-4k km, I've already done more than double with no requirements for change. And I also know some people who made more than 30k km without a single issue and no changes of silend blocks with the BDS carrier...I begin to realize that my cush drive rubbers may be toast. Jerkiness is really awful these days at 6000km.
The F3 800 RC 2018, while being a Euro 4 bike still carries the old style Euro 3 cush drive unit apparently.
I have contacted my dealer to check if MV is willing to "recall" my old drive entirely for a newer one. If not, I'll just change the rubbers and look closer at the BDS-system, which looks really nice. Any long term experiences of them so far?
