How long have you had the bike? has it always done it or have the vibes recently started? Have you added any accessories?
Do the vibes come on at certain engine speeds. Do the vibes come on at certain road speeds?
How many miles have you got on your tyres?
What make of tyres are you running?
Used to get a numb right hand on my 2014, but I don't remember it happening after the bike had done around 5k. I put grip puppies on, which think must have helped also don't grip the bars too hard. Didn't notice if after that and haven't had any issues with my 1250. Also ride a 2015 RTP which has 30k on it and I haven't notice any vibration.
Turns out the dealer hadn’t actually inflated the front and back tires to the correct pressures �� and the fact the service light was on when I picked it up is another story which to be fair they have now sorted by way of a service at the local BMW dealer.
