I'm looking into 1190's or maybe 1090's.. Is there an issue with high speed wobbles?
Not that I know of - some folk say the wobble fully loaded at high speed, but had my 1190 with huge panniers fully loaded at about 115 on the Autobahn, in Comfort mode it weaved a bit, but changed to Street mode and it went away, many bikes wobble a bit at high speed when heavily loaded - but if you want to cruise at 125 mph with luggage your looking at the wrong genre of bike!
Both bikes are great, but the 1190 engine is much stronger than the extra 100cc / 25 BHP may suggest, the way the power builds is highly addictive, the 1090 is still good, and probably as good or better than the competition (V-Strom 1000 / Versys / Tiger 800 / GS 850) but if you're a power / adrenaline junkie go for the 1190!
IMO the 1090S handles a bit better, the forks have better damping, the 1190 is a bit soft up front, but does absorb bumps real well, but for thrashing through the curves I loved the 1090, the steering may also be a bit sweeter due to it having skinner tyres - but either way it is still a great fun bike.
When I stuck the deposit on the 1290 one of the others had to go, I was in two minds so let the Mrs decide, she had clocked a few thousand miles on the 1090 already, we swapped bikes for about 3 miles one day so she could see how the 1190 compared and when we went to swap back she had a grin that said it all - we kept the 1190....
...but the current prices for the 1090s make them a bargain that cannot be ignored!
Win / Win really.
