Best bet? About ever 10mph or higher is what I do that seems to be best. Or? Listen to her
On a stock bike yes...I can hit 30 in first gear easy...if you have aftermaket pipes/jet kit/sprockets..your shifting will change...it's just like a car you will learn to shift by feel and sound of your bike..
These speeds are too low. Add at least 10mph to each shift.
Really?? It's probably because the aftermarket exhaust. I never rode the bike with stock exhaust so I went by ear and by owners manual even though the manual has you shifting every 10 km/h.
(12, 19, 25, 31-mph)
