What are the best mods for Z50r Suspension, pictures please!

[siktendenciesracing]

I am looking to race the 8" vintage class in vegas and was wondering if any of you guys have put aftermarket swingarms and shocks, front suspension, disc brakes on the stock hubs,, etc, etc. Show me what you've done, thanks.



Here is the Class info off of the Mini Moto SX website:

i would think two fox floats, elkas, or works shocks and sp5's with kitaco monkey clamps... dont know if that would fit the wheelbase or not though

Are the SP5's better then the XR70 forks or our they the same thing??

I took a pair of 50 forks and machined down the front hub to fit on them work out awsome.

chp had fox floats on the rear of one and I am going to get a set for my beast for vegas next year.

Anybody try the TB 330mm resi shocks? They look like they are adjustable.

[firepower354]

Without clarification, I guess I'm sending a close ratio 3 speed with Special clutch on a +R undersquare motor, ceramic bearings, polished gears, coated everything, "unique" exhaust. Should make them add a few lines to next year's rulebook.lol

[Staggs Racing]

Tim you should build one it was one of the funest classes I have ever raced in vegas and I think over the years I have raced about all of them now LOL

what do you say,, you want to get way over our head in a 8" wheel class bike made for a 2 year old?? LOL

Well, here is a few pics of Mine!! All custom front end, with a machined billet front bub with disc brakes. Billet tripple clamps, works rear shocks, lengthed stock swinger. If I can get my back healed up by then I do plan on defending my #1 plate. Haven't thrown a leg over a bike since August.



Things it needs, close ratio trans, better front forks and a little more pwr..lol I think a few guys last yr were a little over 88cc.. Exspecially the older guy with the red bikes. That had to be a 124.

What forks are those??



What wheels are those?? Are they the stock wheels with an adapter for the disc brake set up???



Also, do you guys reinforce the frames or are they aftermarket frames?? or do you just run the stock frames??

[DNRCustoms]

the rear hub is stock, the front hub is a one off machined hub that I drew up and adapted a Julie BMX front brake setup too. I made all this stuff about 8 yrs ago believe it or not. I was rocking My Z when pitbikes first started to get big. I have some spare disc brake stuff laying around I may try to fab up for the rear. I already have a rear hub 90% done that I machined up that I never finished. If your looking for a bolt on deal, you won't find it. Atleast nothing worth while. I've been trying to talk Duane at BBR to make some stuff. But I don't think there is enough demand to make it worth while.. I kinda think it is cooler to have one off stuff that nobody else has!! Just like My pipe, My father in law Hi-Tech Horsepower made the pipe, it is a one off with a carbon fiber silencer. It literally weighs nothing!!



MY forks are off a 1972 MR50!!! They are from my first bike I ever rode 23yrs ago!! I reinforced my stock frame, it is absolutly necessary if you plan on jumping.



I think this year there definatly over 20 entries, I just hope they tech a little more. they need to check stroke. Because I know guys will be cheating this yr!!!

If I can get a hold of a Z for cheap (around $250) I will make some Disc brake adapters for these bikes after I figure out the best forks, and rear swingarm/shocks to run.



What is the best forks to run? Do the marzocchi forks work with these bikes??

[507 brett]

fast 50s makes frames and swingers for the z

[benthepro]

I have put speed forks on my old z50 i had but had run a crf50 front wheel and less you made some billet clamps so z50 wheel would fit in



i also tryed a fat elka off a 50 bbr frame what would work



think best set up would be



speed forks with one off billet clamps to take z50 wheel

fast50s z50 frame

fast50s z50 swingarm

2 fat elka shock's

88 superhead +r "ts" etc etc lol
