I forgot to mention that the ZB for sale in the link above this post has a Monkey R seat which I think is strange for a bike with that low KM.
The pic below has a ZB50 seat compared to a Monkey R seat.
I've put up my ZB50 for sale again. I have a build thread on here. Havn't touched it in at least 2 years but i've acquired almost all of the hard to find parts. Just needs to be painted (personal preference) and assembled. I'm asking a hair less than what I have invested. $1,300. I'm in no hurry to sell the bike (hence my price tag) PM me for more details. -Kyle
