The HAYNES Honda CX500 V-Twin Owners Workshop Manual 1978 onwards (published in 1979 - ISBN 085696 442 5) states on page 90:
Fork capacity (per leg): 135 - 140 cc (4.5/3.8 - 4.7/3.9 US/Imp fl oz). Damping fluid type: Automatic Transmission Fluid (ATF).
Front Forks: Type - Telescopic, oil-damped.
Spring free length:-
Upper spring ... 98.2mm (3.87in) Service limit ... 90.1mm (3.55in)
Lower spring ... 461.7mm (18.18in) Service limit ... 449.5mm (17.70in)
Stanchion bend (max) ... 0.2mm (0.008in)
Note however page 94 states 135 - 145 cc (4.5/3.8 - 4.7/3.9 US/Imp fl oz) of ATF fluid.
Don't use ATF, it's rubbish, despite what the Haynes book of lies tells you. ATF fluid foams and looses all damping capability when under load. Use a minimum fork oil weight of 5 and a maximum of 15 if you ride a CX500 z/A/B model (78-83).
You can go to a heavier weight oil if you have a Silverwing Interstate (500 or 650) but only 20 weight max, any more than this and you run the real risk of blowing the fork seals - from trial and error the members of the CX-GL MCC UK have found that its better to put a loading slug in the top of the fork on all models, than it is to try and increase damping effect with a heavier fork oil.

WARNING - There are at least two know errors in the Haynes workshop manuals which, despite being pointed out to them, they persist in publishing year after year!
what is the fork level height for a 1995 CR 125 honda
110MM air gap from top of fork leg fully compressed with the springs out
Manual says 5.4oz
210 cc or 7.1 oz
for model 1996-2004 the oil capacity per fork is 477cc, or 82mm from the top of the fork tube when fully compressed (no spring inside)
For this bike, the front forks will hold 170cc or 5.8oz.
My owners manual says 140cc or 4.7 ozs.
449cc in each fork. You can also follow the general rule of filling up until there are 10 cm from the top of the fork to the upper oil level in each fork.
From my under standing if your riding MOTO, with a fork oil level gauge you measure put 110 mm.
The V65 Magna takes 580cc in the left fork and 565cc in the right fork, according to the manual. The difference in volume is related to the anti-dive modulator on the left fork. Left and right references are as you sit on the bike.
This bike, which was also known as the Honda Hawk, has front forks that will hold 150 ml of fork oil for each fork.
It takes 5.6 oz of fork oil in each fork.
