I have a lot of experience riding.......but almost all of it was on a motocross, enduro, dual-sport or trials bike that weighed 250 pounds or less. My trials bike weighs 165 pounds and was my only motorcycle for severeal years prior to buying the Savage.....and the 350 pound Savage felt like a heavy bike in comparison.
Last winter my wife and I rented a Harley Ultra Classic for a day while visiting Florida, and this was before I had my Savage and put some street miles under my butt. The Harley felt fine out on the highway and anything over 15 mph was a piece of cake. In town, and when at rest the weight of the bike was impressive. The wide tank and wide seat made it impossible to have your legs near vertical when stopping - and my legs were splayed out at angles that made it hard to support the bike if it wasn't vertical. At one stop light I came to a stop and put my left foot out on the ground while my right foot was on the brake - and as I leaned the bike every so slightly to the left.....my wife leaned left to look at something!

I had a very brief Sumo-Session with my left leg as I worked to keep everything vertical. I am 5'-8" tall and weigh 156 pounds and I am in great shape as I work out at the gym for an hour and half every morning.......I would guess the motorcycle and my wife combined was about 850 pounds and it was a challenge to keep it vertical. I also made a mistake of parking the bike under a tree in a gravel parking lot, and when I came back there were cars on both side that prevented me from being able to swing the bike around. I had to get on the bike and slowly back-pedal the bike on the slippery leaves to get it back out of the parking space......I learned a lesson on how to park a big heavy bike in that episode.
I am certain that riding a heavy bike is possible......however having riding experience and being a good rider is certainly is a plus. You need to adapt your riding and parking style to the weight of the bike. I did find that riding out on the road was great.....around town it felt cumbersome and bulky compared to the smaller bikes.
It cost us $ 85 to rent the bike from 9:00 AM to 5:00 PM, it woudl have been $ 140 for a 24 hour period. We had a fun time, got to experience what it was like to ride an $ 14,000 bike, and learned what it was like to ride a big Harley. I believe it was money well spent, and I enjoyed it much more than I would have enjoyed Disney World! If you want to experience a big bike before you go buy one.....rent one!
