Beware the Z series shock. It's an emulsion shock (the lowest spec type) and may not be significantly, or any, better than your standard. shock.This is very interesting. I hope someone can provide a hands on review with a YSS shock at some point, they are very inexpensive!
Wemoto has the 'Z series' listed for under £300. That's less than the other cheapest option I've found, the M-Shock from Shock Factory at £350.

Do u think YSS is not a reputable company???My advice is to buy from a reputable company, and buy one that's fully rebuildable,
Don't buy on price alone, Would you believe the standard rear shock is £380 from a dealer
