Thatís correct, the RS has rebound adjustment on both legs, and both cartridges are the same. Itís the bottom bracket on NonBPF (like the RS ) that have the compression adjuster built into it. As you can see on the RS no adjustment on the left side for compression. And the reason I called the RS bottom of the barrel is because not only is there no com, adjustment but the cartridges are all steel along with the rods. I know itís a small thing but the ZX line gets all aluminum. BTW I did at first change out the pistons from a standard ZX 10r with shim stacks in the stock RS cartridge. And that alone was a fairly big improvement. That is probably the cheapest fix for stock forks, considering those parts are dirt cheap. And if you can do it yourself and have no money itís a no brainer. Consider also you can buy a race tech gold valve and install the 6r piston set up fairly inexpensively. Itís no match for a BPF but a lot easier if you donít have the skills or equipment to go that route.
