This should be my last post on this subject. I applied an 8% stock speedo correction to my Speedo DRD, along with the 14/46 to 15/39 correction, and took it for a test ride on a downhill and then uphill very twisty six miles of road.
When I first bought this bike, I had the sinking feeling that I would be selling it soon. It was just too impractical. But after this gearing change, it feels like a normal motorcycle, although not an overly powerful one. HUGE improvement.
I'm happy. Around town, I have always had the habit of shifting from 1rst to 3rd and from 3rd to 5th, unless traffic was very aggressive. I was able to do that today with this gearing on this bike--no issues. I cannot imagine why people would want to stick with stock gearing. The bike's powerband is plenty broad enough to handle taller gearing. Stock gearing is foolish. What was Suzuki thinking?
I hope this helps.
