Hello. I just switched to a 14t front with stock 42t rear. I REALLY like the low end zip and better off road manners but after 70 it seems to start being a bit buzzy and the motor sounds stressed a bit. Is it? Would love this set up if the DR had a 6th gear!!!! I would like to retain the 525 chain, and there are not many options for gearing. I was wondering if dropping one tooth off the rear to a 41t would give that little extra RPM drop I am looking for or would it be negligible? I ride all kind of styles with this bike and am trying to find optimum gearing as here there is a lot of on road/off road transitions and wish not to keep changing sprockets. Just trying to create my perfect for me Adventure bike. Any info and or recommendations would be appreciated. Thanks!
