Hi there, Newbie here, American living in Argentina .....I recently bought my first Iron 883 (2017), incredible motorcycle, BUT with only 200 miles when stopping using only the rear break, I get this acute sound when stopping.
I will have service in 5 days...really strange because it is a new unit. I also have difficulty finding the NEUTRAL position, 50% of the time...but I agree, probably lack of practice..

Great forum, Thanks everyone!
