Fork oil amount

Recommended Posts

More than likely I'm asking a stupid question here. I'm trying to verify the correct amount of oil to use in my forks. I was looking at the specs and it says 110 I'm assuming mililiters. Then next to it is says 4.3 no indication if thats ounces or inches.This is for my bike an '03 cbr 600rr. Can someone help me verify this level thanks.

110 milliliters is the right range for fork oil. But not for a 2003 CB600RR

110 milliliters is 3.72 US fluid ounce.

I have no idea what 4.2 would be.

It's not on this very handy conversion.

Found it. My copy of factory service manual says:

Recommended Fork Fluid:

Pro Honda Suspension Fluid SS-8

Fork Fluid Capacity:

531 +- 2.5cm3 (18.0 +-0.08 US oz, 18.7 +-0.09 Imp oz)

It also says to then measure level: (from top of fork down, after pumping forks to remove air)

Fork Fluid Level:

110mm (4.3 in)

a cubic centimeter is the same liquid size as a milliliter.

if you're wondering how much to buy then it's usually just one quart for both forks.

you want to fill the fork without the spring in it to a specific height in the tube. you'll need to measure it or use a fork oil height tool like this, http://www.motionpro.com/motorcycle/partno/08-0121/

this tool allows you to just pour in the oil then set the level on the metal tube with the stop and suck out the extra oil. way easier than measuring it with something.

it's a great tool. I went ahead and bought one for myself and man it's so much nicer knowing 100% that your oil level is dead nuts accurate.

Thanks guys I've already bought two quarts because I have to replace my fork seals also I just got confused on how the specs were layer out.

When you change it be sure to measure the distance from the top. If you don't get it all out it will be wrong. And you could end up with two different levels. A coat hanger and some plastic tubing really make that easy and accurate.

Different bike but nice write-up here on what I mean.

I got one of the forks apart an drained the oil it was a dark gray color. I'm gonna ghetto-engineer an seal driver out of some pvc an some scrap metal to compress the spring so I can get it back together. Ran out of time last night so that's on the agenda for today.
