Hey all,
Looking if anyone has rear shock specs on the 2016 SE model. Eventually it will be Ohlins, but until then I will be running the stocker. Looking basically for spring preload numbers. I have the 2012 ZX14R manual from here.......but the spring installed height is far different on the 2016. At this point I can't measure sag with both of us on the bike. I had the girlfriend measure with just me, and it was damn near perfect. I am going to try it today with the spring preload wound tighter by 2 turns. If anyone has or knows how much each turn changes preload or sag numbers it would be helpful.
Thanks, Ross

What I have indicated in my maintenance log is that each 360° turn of the adjuster nut results in approximately a 3.5 mm increase/decrease in loaded sag. This is for a 2008 stock shock.

You can measure sag pretty well with both of you on the bike. This method seemed to work great for me. Get on nice and easy. Maybe set a cynder block on each side of the bike to stand on so you can lower yourselves onto the seat without bouncing.

Thanks Rook
Now I understand that method a bit more. As the 2012 numbers in the manual here are not even close to the numbers on mine. I will try this...good idea there!!
I noticed you were using a swingarm stand versus rear fully extended shock. The 30-40 mm of sag I believe is fully extended to fully compressed loaded....am I right?

Here's my tutorial. Sorry no pics right now.

I noticed you were using a swingarm stand versus rear fully extended shock.

I first used a swing arm pivot stand to allow full extension of the shock. Measure between center of axle and a fixed point (the downward point on the tail fairing is a good spot).

Now to arrive at the amount the shock compresses when fully loaded:

1) I put the bike on a rear spool stand to compress the suspension under the bike's weight. I also used a fork lift stand to raise the front even with the back so the weight was distributed normally. Measure the compression caused by bike weight using the axle center and same fixed point.

2) Then get on the bike carefully with all gear to measure the additional amount of fully loaded compression using the card.

Subtract the extra amount of compression measured on the card from the bike weight meaaurement to arrive at the total loaded measurement of compression. if you have someone to measure between the fixed points, you can just get on the bike without breaking the measurement up into two steps. Subtract the total loaded measurement from the full extension measurement and you have your sag----the difference between full extension height (no weight)and fully loaded height (all weight).

The 30-40 mm of sag I believe is fully extended to fully compressed loaded....am I right?

The measurement commonly referred to as "sag" is the DIFFERENCE between unloaded (no weight on the shock)and fully loaded (bike, rider, passenger and all gear and equipment you intend to carry). So to illustrate this simply, if your unloaded measurement is 15 inches and your totally loaded measurement is 14 inches, the sag is 1 inch. Conert to millimeters.

General sag for street riding should be 35mm to 40mm, front and 30mm to 35mm, rear.
