The shock you bought will not allow you to adjust compresson and rebound separately.
That sounds awful, but in reality will end up being no big deal. When suzuki puts a shock on this bike, it might cost them 50.00. You can look on that AliBaba import site to get an idea of how cheap someone can buy 100 shocks, then consider Suzuki bought 1000's of them.
Of course, the cheap shock will come with a spring and damping rates selected by the legal department. The shock has to work on a 150lb rider, or the 300lb rider and his 350lb girlfriend.
When you bought this Nitron, it is set up for your weight and probably a glance at your riding ability.
What it means is that this expensive shock will be very close to ideal, right out of the box, so you will not be needing to make any big changes to it.
I own a Penske shock for my bike. It has 28 compression and 30 rebound (or whatever it has).
I've played with the adjustments a lot, but its so close to stock settings, now, that if I had no adjustments, that would be fine. If I'm two clicks away from when the shock showed up, I'd be surprised.
I'd give it a thousand miles before adjusting. The internal pieces have a tight tolerance and do need a break in. If you adjust early, you just chase your tail (uh, I know this guy....)
I'll say it like this. You probably saved several hundred dollars and ended up with 97% of what the more expensive shock offers.
I halfway wish Id done the same. The reservoir is a pita when the bike is not equipped with one.
