Bought one of these to replace my trusty but ageing C90. After about a week it developed an irritating vibration from the front headlamp unit whenever I changed gear. Today I took it for its 600 mile service and I asked them to look at it and rectify the fault. After getting the bike back I checked the lamp and found that it was still moving around. One of the bods at the dealership saw me doing this and asked if everything was alright and I asked if they'd done the work on the headlamp. His reply was "yes, but we get a lot of complaints about this problem" He checked with the mechanic who said he'd stuck some foam round the inside of the unit and told me that the problem is that "there are only 2 small clips holding the thing in place" Needless to say, the foam has had little effect.... So..... is that it then?! Am I now stuck with a bike with an irritating vibration just because they didn't build the thing to a decent enough standard? Any thoughts would be much appreciated cheers.
