Fitted the 43T and much happier with the low end and still pulls well, still need a PCV etc to reduce the jerkiness.I also went with a 43 tooth rear and i am happy with the results, bike just feels better at low speed town riding and I feel it hasn't lost anything mid range or top end.
Perhaps because not everyone has the same view of riding as you. For example, and yes he stunts and yes it is a sales video but he could easily also sell longer gears if he agreed with you.Hi all, new to the forum but came across this thread and thought I would pass on my set-up.
I have a 2017 390 Duke which I use for commuting, touring and squirting in the hills.
So, after experimenting (playing with gearing is both cheap and easy) I settled on 16/42.
Other than stunting, I cannot understand why some folks go even shorter gearing than stock.
