I have both: an Adv 03 1150 with twin spark, Servo ABS. It is a brilliant bike, easy to ride, plenty of flexibility in the motor (stick in top at 40 and forget the gears until you come to stop) Overtaking in top is no problem - just wind it on and she'll pick up cleanly and fast - if you drop a gear it'll go like a R1. I have left several sportsbikes behind on overtakes - the Gs has lower gearing so accelerates faster, but runs out of puff at about 115.
I also have a 2002 1150, standard version, single spark, non servo ABS. The gearing is different, she rides completly different to the taller Adv. It feels as though the steering geometry is different, even if it isn't it feels different. That may be just the lower stance of the standard 1150 over the taller legs of the Adv.

The single spark is quite a bit quicker than the Adv, it picks up just as fast, it just does what is required - a great bike too.
i won't be selling either of them. Sometimes it is difficult to choose which to go on. The older bike has more range as I have a 41 litre tank on it. About 150 or so more miles to the tankful....very useful in rural France over the weekend.

Ever tried getting fuel on a Sunday in the sticks in France? The 41 litres keeps the bike and camping stove going fo rthe entire weekend - fill and forget until Monday.
I don't think there is a BAD 1150 made - even the twin spark coil packs don't give trouble anymore. I had to replace ONE of them - the other one is still th eoriginal, so they don't all fail. The new, replacement ones don't break.
You will be very happy with a single spark version. Just don't get a 1200......
