Which model?

Hi Dave

I'm pretty sure the NX5 went from 1993-2000, from 2001 on it was the NXA. So your 2003 would be NXa.

If you visit:

http://www.tsrworldwide.com/

and use the parts books on there, you can work out which model bike the forks you have come from.

If you have an NX5 let me know, I have a manual so I can look it up for you. If it's NXA, best bet is to try calling a race bike dealer.

Cheers

Dan

NXA (2001-200X) forks have the following standard service data for them:

Fork Fluid:
Honda Ultra Cushion Oil Special (SAE 5W)

Fork Oil Level:
140 (5.5)/423 cm3 with fork set collar (t=11 mm/0.4 in)

Now I am sure that is extremely helpful Smile

So his is some more details from the manual:

You must use the fork set collar for correct oil level adjustment

Measure the oil level from the top of the outer tube.

Standard Oil Level:
140 mm (5.5 in) with fork set collar (t=11/0.4 in)

Standard Oil Capacity:
423 cm3 (14.3 US oz, 14.9 Imp oz)

Yes, 14.3 US oz of SAW 5W suspension fluid.

of course you should not only put in the recommended fluid level, as well as measure as per mentioned.
