Ya.......... I think so . but it is a high performance racing chain for a 85cc / so might be ok on the 8hp Z' if your staying with the stock motor......... Your call !
.
They don't even show a nz2' anymore on there site (discontinued ?)
looks like they upgraded to the nz3' now for 150cc
.
theres a note about the nz2' on there new chart (pic)
*NOTE: Former ERT & 420NZ2 Connecting Links are not interchangable.

A weaker chain will have a significantly shorter interval between adjustments needed, and also a much shorter life, for bOTH the chain and the 2 sprockets. If I were you, I'd get the correct chain asap before the 2 sprockets get worn by the rapidly stretching weak chain.

Chains for the Z125 are not expensive.

Also, be sure to get an o-ring chain. Some chains, which are either (a) cheaper or (b) intended for racing only, do not have o-rings. They require MUCH more frequent lubrication and are particularly weak on wear when run in the rain.
