2017 650 exec with Battlax front tire seems to be humming more especially when I move the bike from side to side but less when travelling straight. The bike has 12800 miles on and I doubt if it is wheel bearings starting to hum along. Could it be the Battlax tire nearing its end? Could the humming be coming from the tire or is it just the sound made by the variator and or transmission. I read somewhere on this forum someone mention how he loves the humming sound these bikes produce.
