I went to the launch at Jeffries in Shipley - just for a look as I can't afford one. I thought there were some improvements, practical and aesthetic over my '08 1200adv. There was
no info
on whether mpg was any better on the new model and yes, I did ask. Like Sooty I do relatively high mileage, I don't have wads of cash so fuel economy matters to me. The 1200 gives significantly better MPG than the 1150 as well as more power. In this simplified but to me important comparison, the new bike seems to be a backward step ?
In fairness if I wanted a powerful bike I wouldn't be riding a GS, the 1150 makes quite enough horses for my needs, the 1200 if I'm in a sporty mood.
I'm not wishing to knock GS's of any vintage, I think they are great bikes. I don't see an improvement in the most fundamental areas that matter to me.
