well depends on if you want to keep your fat front tire. TBparts has swinger and shocks you can buy new. CHP also has swinger and shocks. fast50s has a swinger. Asianconcept designs i think it is has a swinger on ebay sometimes. lots of option for the rear that are not bad on price. the front will prolly be a custom job. most of the stuff you can buy premade cost a lot and is for street.
my z
old honda forks from xr/xl80 or 75 i dont know and te top clamp is from an 81 xr100. front wheel is KTM 50 with drum brake plate from the rear of a Xtreme pit pro107(modified).
I'd like to get a set of wider tripleclamps so i could get my z wheel fit between the forks.
rear shock are from twin shock xr80. my swingarm is homemade but the shock will fit on stock. If I go that route I have a set of 32 zokes laying around that need triples for the Z.
Sik Tendencies is selling a roller of a Z50 that has zokes custom fit on it and retains that wide Z rims.
