I just finished a job, where a dude brought in his 2015 R6, worried that there is something wrong with his gear box. I took it for a test ride and it had a severe ticking noise. Only to find a battery strap caught up in the front sprocket. I asked him where's his battery strap was. He said he lost it the last battery change 18 months ago. So this thing had been curled up in the front sprocket for all that time and nothing bad happened.
