Marzocchi RAC Forks

VaporMV · 11-18-2012, 07:01 PM

I have the oppertunity to purchase a set of brand new Marzocchi 43mm RAC forks for a crazy low price from a good friend. Does anyone have experience with these forks? If so are they a good product? Lastly does anyone know if they will bolt straight to my F3? I know the dimensions of the RAC fork but can't seem to find the dimensions for the stock fork.

Well since nobody has chipped in any info I would have a go.
Firstly, what is wrong with your forks?
What did the Marzocchi's come out of, what are they sprung for ?
You will have to check more than just the dia of the forks mate, what about the lenght, stroke, mudguard mount, brake caliper set-up and also axle size and fittings ?
Many things to look at before spending the $.

There is nothing wrong with the stock forks really, they just have a harshness that I can not seem to dial out. The Marzocchi RAC forks are supposed to have a very large range of adjustability and should be plush and controlled at the same time. I have all the numbers info on the things you mention except for the spring. Once I find out what would need to be done to fit them may make the purchase pointless so I figured I would ask here if anyone could help me find the info I need. Also, getting a $2400 fork for $300 makes it worth a bit of time to see if I can make them work.

For that cheap i would have already bought them. If they dont work u can always make a few dollars off them.

I thought the same thing but my buddy would be doing it as a favor and if the dont work on my F3 he can sell them for alot more on ebay.

Gotcha. Good friend you have there. Hope they work out for you.

Ok, I found out the spring rate is 9.5Kg/mm. So I believe that would suit a 140-175 pound rider correct?

Hi,VaporMV , correct for this spring
Did you see there is a bolt on each leg near the caliper holder?(inside )
Is it for to drain the oil? It would be interesting...
cheers

If that's a front fork spring rate, shouldn't it be .95 kg/mm, not 9.5 kg/mm?
