I agree that a little loose chain is better than a little tight. I just traded in my 2011 Suzuki gsx1250 for my new tracer900. I had the original chain and sprockets with 56000 miles on them and not ready for replacement
I cleaned and waxed the chain every 200 miles and used dupont degreaser and chain saver.I believe riding conservatively puts less strain on the chain vs
riding like a maniac!
