Hi Gents,
I got my red Icon last week and did about 200km so far. I noted a delicate vibration that increases its frequency in line with the speed. It is only noted at above 50km. I checked it with the engine disengage, on different gears and engine revs, on different type of surfaces and it is still there. It most definitely be the tires defect or simply wheel balancing issue. But I was wondering if anyone experienced the same problem and if this would be common for this sort of dual purpose tires. My old bike is Monster 696 with 15k and it runs like a Swiss watch compering to the Scrambler - no vibrations from wheels at all (it has Contisport Attack 2).

Is the vibration from the tires wobbling at thigh speed or does it feel more like it is because parts are not tightened and holding together properly? I would guess that it can be taken care of by the dealer though since its not a problem that everyone is experiencing. Probably just needs a tune up of some kind.

Maybe you want to check if the tire pressure is too high. If you filled it to rated pressure on a cold day it could be too high when warmer. However, your area should be cooling down now :) Just guessing. Somebody mentioned a resonant helmet noise http://www.ducatiscramblerforum.com/forum/wheels-tires-suspension/6753-helmet-noise.html#post77177, and I have had something similar, thought I could feel the vibes through the handle bar and at the same time hear a very low pitched hum. Was definitively not the engine, independent of revving. Do not know what it is. Checked my tire pressure and it was on the high side (first warm spring day). Do not know if this is related to it.

Update on the vibration issue. I had the bike checked by the dealer twice. The first time they confirmed the vibration and found it to come from too tight factory chain setting. They adjusted the chain and checked tyre pressure. They confirmed the wheel and tyre runout to be within factory limits so did not do anything to the wheel. Upon test ride I noticed the vibe is still there so on the second occassion they rebalanced the wheel and found it to be 5mg off - this was corrected. I can not feel vibrations other than from road bumps and the bike seems to be fine now :)

They adviced these tires are dual purpose and they will generate some vibes anyway. I sort of agree with them when it comes to vibe from the thread but this was different and I am glad I kept pushing to get this done properly.

I have the same issues with my 2020 Icon Dark's front tyres, so your story is not individual. My 1000 km service will come soon, thank you for kind descriptions of experiences! ;)
