Universal rear shock absorber for chinese bike.
 

Has anyone ever replaced their stock rear shock with a universal or OEM shock?

I have a HSUN 2007 VIVA enduro which I've owned for just a few years. I want to replace it's rear shock with one which has a higher preload rating. I've done all the measurements on the original shock but when I started my search a few days ago for a new one. I ran into measurement problems on shock lengths and eyes widths compared to my rear shock. I came upon a lot of rear shocks that had a length of 270-280mm and even some that have 300-335mm lengths that claim they are universal.:hmm: But I still worry about length and eye offset issues when replacing my original rear shock with another OEM or universal shock. :doh:

So, does anyone have a suggestion based on experience when buying a new one. Because frankly, I don't have time to do any upgrading to my frame in order to use another type of shock absorber. And buying another stock one defeats my purpose all together.

Thanks to all in advance for your help and suggestions.:thanks:

BTW, I claim this post for china!

I've read several of the early posts on this forum (from before my time here) that point to a Yamaha R6 shock as a good choice. I've never tried it, so I have no first hand experience.

You could also ask Humanbeing for his opinion, since he can likely point to shocks in China that would fit and be better than the original.

I also seem to remember someone reporting he substituted a Yamaha, R6 shock absorber. However, I wasn't positive, so I waited for someone else to mention it first. ;)

FASTACE 's (100% owned by Taiwanese / Factory in Guangdong...) product quite popular in mainland China http://yueye023.taobao.com/search.ht...Type=price_asc .

I put a yamaha R6 shock on my bike. It is longer than the stocker and had to compress it to make it fit. Rides real nice on the road and is pretty good for light off road duty.

R6 shock is ~300mm.

Did you start a thread on that? I can't recall..

Did you need to mod the bike at all to accept the R6 shock? Do you know which year your R6 shock is from?

That link didn't work for me. I got a login screen and an image of a very scary baby.

I did some research on that before, and I think it depends on the year.

I did not mod the bike. I had to use spring compressors to compress it enough to mount it. I bought a R6 shock off ebay that said it was for a 99-02. I got the idea after seeing this thread

I also got info from red2003 and his mod

Thanks for taking the time to capture, and post the excellent photographs, Ed. :tup:

Did you get the spring compressors from Tusk, or somewhere else? Can you provide a link for them? I see the Yamaha R6 shock has adjustable rebound damping. :) Can you also adjust the compression damping? How do you like the performance of the R6 shock absorber?
