I ride 2 up probably 60 - 70% of the time and my wife even commented on how much better the bike felt with the 28T. She noticed the extra mechanical advantage translated into being pushed back into the back (butt) rest harder, especially in the higher gears. Probably one of the reasons I like it is because it makes the bike feel lighter when I ride 2 up. With her, me and some gear we're probably 330 lbs.
You're right John, the bike loves RPMs. 4000 rpm in the 65mph range is very smooth, 5000 rpm in the 80mph range is almost electric smooth and the roll on acceleration
BTW, <1/4" chicken strip and I still haven't scraped anything..... Took some nice switchbacks yesterday 2 up in 3rd working between 4000 - 8000 rpm and not a scratch. Maybe I have the "extra ground clearance" version or maybe the bike isn't as leaned over when you're taking a 30 mph turn at 70
Shocked a couple of crotch rockets when they didn't pull away from me through the turns or on the straight. Keep the V-Rod above 5000 rpm and the bike will stay with almost anything in short spurts. Of course it they know what they are doing and/or don't get caught off guard you're toast
