With a 19 T you'll be 3380 rpm @ 60mph, 3940 @ 70 and 4500 @ 80mph in 5th gear according to the chart.
I ran 17, 18 and opted for the 19 for its relaxed cruising speed and slightly better fuel consumption. It also stopped me feeling for another gear at 50 mph.
No noticeable lack of acceleration detected...just hang onto each gear a bit longer.
I have a Triumph T100 Bonneville with an 18 tooth front sprocket Im thinking about replacing it with a 19 tooth sprocket is there any reduction in engine revs at cruise speed with the 19 tooth and if so how much would it be if any?
