Bloody hell! Not ANOTHER Simon!
Simon,
if I had my chance again, I would go with the sport option. If I remember correctly, 1 to 5 are the same as the standard box. The 6th, or 'E' gear is a very high overdrive. I spend most of my time ripping up A and B roads, and it's extremely rare that I ever use 6th. I found it useful for long hauls on the Autobahn (the quick way to get to the good roads) but not much use on motorways in this country. With all the traffic over here I'm constantly changing down to 5th. I only ever use it above 80 mph.
1st is also a bit tall, and would prefer the gearing of the 1100.
I'm considering fitting the final drive from an 1100GS, as a few people in the US have done. You'll know what I'm talking about because I've seen your post on ADVRider.
Hope this helps.
Steve.
