I'd like to know what rpms 900 Monsters, & SSs (I assume they have the same gearing) turn @ 75 mph, in 6th gear, with stock gearing. I'm interested in all years. Also, I would be interested in the answer to the same question re. the ST4. Finally, can anyone recommend hard bags for the Monster? I know there was a "City" model, with standard hard bags, available in Europe, but I've never seen such a setup available in the U.S. Thanks to all of you in advance for your help!
