So are you looking for a softer shock/ride? Have to tried to adjust the OEM shock?

How much do you weigh?

If your just looking for a softer spring, just change the spring out, Race Tech has rear springs.

The spring is fairly easy enough to change, and it's a whole lot cheap.

Here is a link that might help you out.

Sidenote: the old Ninja 250 & 500 guys swap out the their OEM shocks, for the Ninja 300 ones. It's got a better spring for heavy riders (200lbs+)

Also have you the sag? And the front springs might need to be changed as well, to keep the balance of the bike.

Hope this helps you out.

That depends on how deep your pockets are, personally going for a fully adjustable shock which could be anywhere from $600 to $1,000.

I might try going with a slightly lesser spring in the rear, that would help.

But one must remember that the Ninja 300 is based on a ninja 250 which is an old antiquated analog design. Unfortunately you're stuck with old technology and an old frame etc etc.

Good luck and if you have any more questions just post them up.

If you want to you could just find a used rear shock off a EX500/Ninja 500r. As it's spring is less stiffer that the 300 one.

The 500 one is at least adjustable like the 300, and it's a true bolt on swap.

I might even have a 500 shock in my pile of spare parts, I could look if you wanted to try it out first.
