You need bottom end torque and midrange punch for the road anyway, not top end, and especially in a 'trailie' like the GS. Higher RPM power and associated gearing isn't needed for everyday riding unless you live near an Autobahn or track.
My daily ride/scratch tool is a Yamaha 'Thundercat' YZF600R (it saves my GS for best), once their 600cc sportsbike until the more extreme R6 was developed to respond to the ever more sports-focussed competition. Despite having slightly less top-end than an R6, it has more bottom and midrange punch and is more real-world road friendly than the more modern 600 sportsbikes. All I've done is enhance the chassis and brakes, the engine is more than enough for the road.
It depends how you ride, but for some people, too much is never enough.....
