Lee as I stated in a previous reply, how often will you top out on speed? In the real world mid range is where you need flexibility and this will give it to you in spades. I have been riding my M1200 with this gearing for years now and would not change. I have never once had the bike flat out, go figure!
My Mut has 15/42 and has seen 154 mph in Germany, coming back from N-Ring. Sat nav said 146 mph. That’s more than ample as Marquez is currently sick and I didn’t want to embarrass him in front of onlookers.!..
