Its not really a focus on power.
I am having to ride the dommie harder than I would like... I don't like redlining my bikes so I want a bit more power.
I would also like a bit more extra weight as it makes me feel more planted.
You'll thrash a Transalp too then. Personally I have no issue with doing this to the GS or the Transalp as they thrive off a bit of abuse.
You could always change the gearing.
Are you off roading it, because if you're not then an old triumph tiger would fit the bill. If you are off roading then you have to decide at what level you are prepared to sacrifice your road/off road ability. The GS is as planted as you'll get on road with a 21" front wheel. The smaller the front wheel the worse off road.
All trailie bikes have to be thrashed on road unless you are prepared to fork out on the newer big stuff (KTM 990 SE etc).
The Dommie does have a top speed of around 100mph like the Dak, the Transalp has another wheel weaving 10mph if your brave.
You could always look for a twistier route to your destination
If you're already travelling the back lanes at full chat, then you might be better with a bandit 600 and a cheap trailie for green laning?????
