says, there are trade-offs. Depends a lot on how you ride. At your weight you're probably on the min setting without bottoming out. If you want a softer more cushy ride, leave it where it is. If you ride harder on the twisties, you may want to kick it up a notch or two. The only thing is, the front remains the same and is soft from the factory so your limited there. I upgraded to a stiffer spring after having the bike for a couple weeks. In the curves I was getting a lot of push and the stiffer springs lessened it considerably.

The best thing to do is try different settings and decide what you like best. Adjustments to the rear shocks will affect more than just the bumps. It affects cornering. Experiment. .....
Agreed! In this month's issue of MOTORCYCLE CLASSICS magazine, issue JAN/FEB 2019 VOl. 4 No. 3 it states on pp 55-6 concerning the new Royal Enfield INT 650, I'll paraphrase:
The rider kept missing "...apexes in the turns and had to back off the throttle to pull it back on line..." The solution was "...adding two turns to the preload adjusters on the Gabriel shocks...raised the rear height by 0.31 inches for more weight on the front wheel as well as tightening the effective head angle of the fork...fixed the problem....."
I am coming from an older Triumph Tiger background.
I just tried different preload settings. The guy who owned the bike before me weighed in at maybe 160 and he had the shocks set at 1. He also progressive springs put in the front. I weigh in at 190 and found that I like 3 as the best setting with my tires pumped up to 38 pounds. My riding style is aggressive in corners so I like stiffer suspensions. More personal preference, just try out different settings and see what you like.
