It's a bit strange reading how all you owners of the XR are relishing revving the arse of your bikes because before I tried and bought a GS LC, I had a Yamaha Fazer 1000 2nd generation for 5 years which is a similar sort of bike. Obviously not as technologically advanced but a rev monster all the same. It could do an indicated 80 mph in first gear and I did a timed standing 1/4 mile in 10.9 seconds at Elvington once.
Went touring the Continent on it quite a few times and intended to keep it "forever". That was until I tried the GS with it's less frantic engine and huge torque. It made me realise that I don't actually want to rev the nuts off a bike and that I prefer the lazy but still pokey engine of the GS.
I haven't tried an XR yet but have a feeling it will be out of the same mold as the Fazer. It would be interesting to see, if you could only run, either an XR or a GS which you would choose. I suppose it would depend on what you want out of a bike and where you ride it, but for me, I don't think I would go back to a bike like the Fazer although it's engine smoothness and lack of the "bolts in a bucket noise"would be nice to have in the boxer.
I wonder if all you new owners will eventually tire of it's highly strung nature.
