Well, I'll have a go but I can only guarantee the figures for the "E" box . . .
The ratios for the "E" box are, per 1,000 revs.
1st = 7mph
2nd = 9mph
3rd = 12mph
4th = 14mph
5th = 16mph
E = 21mph
So, if you're doing 5,000 revs, that'll be 60mph in 3rd, 70mph in 4th, 80mph in 5th, and 105mph in "E".
Theoretically, then, at redline of 7,500 revs you should be able to do 158mph but you can't because the bike won't rev out in "E" much beyond 6,500 revs. Redline in 5th is 120mph
The ratios for the sports box are the same as above (I believe) but 6th = 18mph. This gives a theoretical top speed at 7,500 revs of 135mph which is easily reached. In actual fact then, top speed is about 135mph for both boxes (but the theoretical limit for the "E" box is higher).
Your 1100GS will have slightly higher mph per 1000 revs because the gears are further apart. 5th gear on the 1100GS is higher than 5th gear on the 1150. This is the reason people think that the 110GS is faster than the 1150GS. It's not. It's just the different gearing and the way the bike is ridden. Anyway . . .
1150GS:
3rd gear - 2000rpm = 24mph; 2500rpm = 30mph; 3000rpm=36mph
1100GS:
err on the side of caution and keep below 2500 revs in 30mph zone.
1150GS:
4th gear - 2000rpm = 28mph; 2500rpm = 35pm; 3000rpm = 42mph; 4000rpm = 56pmh; 5000rpm = 70mph
1100GS:
I'd keep to 2500rpm in 40mph zones; 4000rpm in 60s; and well below 5000rpm in 70s
1150GS:
5th gear - 4000rpm = 64mph; 4500rpm = 72mph; 5000rpm = 80mph
1100GS:
I'd stick to below 4000rpm on any national limit roads where you think there might be cameras.
Hope this helps.
