Ill watch this thread as i too have a set of Chinese forks I may end up having to use.

Here is another thread with fork travel discussed

Little help and advice please. I’m putting together a FZR250 (3LN) chassis as a bucket. The front forks have about 150mm travel which is lots more than another bucket I rode in the weekend that handled superbly. Question is, should I restrict the travel to say about 75mm whilst I have the forks in pieces and, apart from fitting emulators, is there any other mods that would be worth doing? I was thinking of fitting say a 75mm spacer over the top-out spring and cutting a similar amount from the main spring preload spacer. I’m running 3LN wheels front and rear, 2.75” and 3.5” with a single large disc off the earlier model with a late model 4 pot calliper and slicks both ends.

Any thoughts on the rear shock would be appreciated as well. Stock currently but with the major weight reduction not right I would think.

Mine seem fine for rebound and comp the forks are actually as light if not lighter than mb5 ones.
The yokes are not to bad but the stem is to all intents solid.
But they are no doubt made out of recycled frypans.
I would rather use nsr or CBR but not that easy to find cheap ones.

If built like myne you will find they are held in place by a bush work out how much you need to shorten them by and have that bush then moved further up the stanchion by that ammount and trim off the excess as to how much over hang you had at standered if you get what I mean easiest way I have found.

I just pulled the RS50 forks apart to have a look inside and these are differnt so I need to have the thread in the top caps cut further down the fork
