You should post the pictures you showed us at the bike show.

I most certainly will ! just want it all to be up to standard of the bikes i see here first. Maybe another week.

To be honest i have some reservations about the arm... nothing concrete really just fear of the unknown. I believe its a massive chain inside the transfer case and lubing it is a mystery to me.

Also the breather seems to be below the level of the fluid, which cant be right.

I know Hercules has just installed one before he passes away, but other than him i dont know anyone else who uses this kind of arm.

Any MadMax wide kit I've seen were shaft/gear driven. I've never seen a chain in one.

I just got a chain driven mad max bike in Saturday for transmission work (lot fifth gear). It's got a 280 tire on the rear of it.

MadMax kit? Run the other way...

 

[RJ RJ RJ]

it is a mad max "gear drive" arm... but having looked inside the oil fill hole i have seen what appears to be a very wide chain though i could be wrong....but then again many transfer cases use a chain so it didnt seem surprising to me...especial when you consider two gears would have the shaft dive rotating the wrong way...

Anyway....who here has one? and what is your experience?

We've got one in town here. He's ridden it twice for a total of 20 miles and shelled the gear box out both times. He's now trying to get some custom gears made again. I think the newest version is finally stronger but still not sure it's going to take any kind of power or hard riding.

Not the resounding vote of confidence i was looking for LOL

...Paul assured me on the phone it would take a beating..even at the drag strip. That would not be nice to turn out to be a lie.

i suppose if worse comes to worse i could gut it and fab up a second ujoint position at the differential flange and have a poor mans otec swingarm.

ANyone else know a guy who has this Mad MAx gear driven swing arm? Good or Bad stories?

I worked quite a bit with Hercules (pics of his bike are still in the members area I think). He was pretty confident that the parts he got were heavier duty then the early stuff. I probably even have pics of the arm before he installed it.

ITs sad about his passing.
You helped install it for him? Did you plumb lines to engine oil or just seal it up with gear oil in there?

Thanks dude... any tips on how to contact them?

 

[one2dmax]

I worked via phone and suppling parts. Sorry, I needed to clarify that. He pretty much called me on a daily basis.

Ask on the VMOAtech list..someone there should know

Pics of said arm

That looks a lot different than the ones I have seen.

 

[RJ RJ RJ]

Thats exactly the same as the one i own. although mine is not painted or polished.

I have found another gentleman online who had the earlier more fragile version and he rode it for 2 years before converting to a 330 chain drive set up. He had good things to say about it but did say he had the input shaft break at some point, but that later versions of the arm use bigger gears and is much stronger.

Here is my bike so far:
