Thanks for replying.
OK, point taken but there are other hidden engine mounts other than those used by the Crashbar mounts so I would still suggest getting them all retorqued.
I can understand how the crossbar of the Crashbars could be part of the cause from a resonance point of view. Indeed an L6 that I rode with Touratech Crash Bars, had considerably more vibes than mine with the OEM items. However that crossbar is there to facilitate sharing an impact with the bar on the other side, so removing it is a possible compromise.
One other item to consider that I have seen to cause excessive vibration on another make/model, is a malfunctioning injector. That bike was also a twin and a replacement injector cured the issue. Just something else to get checked out.
As is suggested this is a brand new bike and the dealership should sort it out. If not I would mention to them that Your next port of call will be the importers. to be honest their attitude to date is poor. Perhaps also get a trusted friend to ride the bike for an unbiased opinion ?
