Wow, coming of age! Not much more power, just more refined way of getting the power. I rode my LM3 for 50Kmi before the wreck. It would run away from most 1100's. Then you have to stop, nice newer brakes haul down quicker. Find one(GRiSO) and ride it, you'll like it The 850 wicks up quick w/short stroke. 1100 I like the best. 1200 has the power.
Lots of info here, the GOOD and the not so good.
