New Member Introductions » Front wheel hop/vibration on 2016

This is my first post as I'm a new member and a first time BMW owner. I recently purchased a used 2016 RS with 35,000 km and the previous owner had put new Michelins prior to me purchasing that were put on by a non BMW dealer. On my first few rides I noticed a wheel hop/vibration at around 110 kms per hour and getting progressively worse at higher speed. I took it to the local BMW dealer for the 40,000 service and also had them re-balance the front wheel. The hop/vibration is still there after 800 kms of riding. Is this a characteristic of the bike or could it be something else, maybe a bent rim? TIA for your help.

That is not a charismatic of the RS. It sounds like there is either a defect in one of the tires or one of the wheels that is causing that vibration. However, your dealer should have picked up on either of those issues. If the didn't they were not doing their job, assuming that you asked them to check both wheels and tires thoroughly. The problem might not be in the front wheel, but it could be in the rear. A rear tire imbalance would also be felt as a hop in the front wheel.

The back tire was not checked and that would be a logical place to start. When balancing do they spin them? If not how would they spot tire flaws etc.

A mate had a similar issue on his S1000XR - it turned out that the TPMS sensor had come loose and was rotating around the hub inside the tyre.

Has the rear wheel got any weights on it? A lot of independant shops don't have the adapters to balance single sided rear wheels. I had the same problem with a Speed Triple.

Just had Ocean Plymouth carry out a 12k service and fit new tyres. Two days before I removed front wheel, gave it a good clean and added grease around wheel bearings and the spindle.
I also removed all old wheel weights and cleaned both rims. (used a heat gun, 50degrees warm and the weights unpeel with no marks on the paint)
You would not think it would make much difference on old worn tyres but after 30 miles riding down to service I had numb hands from the very minor vibration. Speed was around 60mph on minor roads.
The ride home and 100 miles since on new, balanced wheels Road 5's have been carpet smooth. Both wheels have balance weights added.

I also experience a "buzzing" through the handlebars and the hopping at higher speed. It's fatiguing after a few hours. The rear wheel has new weights on it but when the old weights were removed the glue/gum was left on so I took it off. That tells me what kind of job was done. I heard that many independent shops do not have the adaptor and rear balance is likely what it is. I'll be taking it in next week to get the rear re-balanced and take it from there. Thanks for the input.

Had them check balance on rear wheel and it was out 3.5 ounces! Now it rides as it should and much more comfortable. In fact I think I'll blow this afternoon and ride!

I am due tyres and thought I'd check with BMW on prices. They were surprisingly competitive and willing to haggle . So, they got the job .
Yes, its not the cheapest but with things like TPS and single sided swingarm they've got all the kit . Life's too short sometimes !
