sprockets steal or alloy?

What ever offroad only sell. Especialy if you know somebody with trade account. Steel back sprocket. Original front from bike manufacturer.

I had one on a wr450 lasted forever, got another on the Gasgas, not been on there too long tho, but like Tanks, shows no sign of ware, sometimes come up on sales..paid £25 for mine....bargain..........and bling

Supersprox that is....
