I started slowly going thru the little Tiger.  I took the dual wheels off.  I have never seen something like this, I expected just to find the usual spacer thing.  It mounts on the solid rear shaft with a collar.  It has some type of clutch mechanism in it, it is not just a solid hub.  I did see where Tiger offered a dual wheel kit.  I was unable to turn it with  both wheels on, but it turns as I would expect with singles.  Any idea what this whole mechanism is about?

I have no actual experience with this but could it be a sort of gear reduction differential so that the outer wheel spins faster than the iner wheel allowing less tire skid during turns? As I mentioned this is just a theory and saying it seems very odd being the amount of work that would go into something like that for very little benefit. I may be very far off and just very tired but hey we all have had strange ideas hit us in the brain pan at times. Take it apart and shoot some pics maybe someone with a higher IQ than me will chime in!

I think it is an idler type hub extension.  In other words the outer wheel is not driven, it just free-wheels on the shaft extension & is there just to spread out the weight distribution.

Just my 2 cents worth.

Well look at that, that seems a lot more feasible than my hair brained idea! And why he couldn't turn it may be due to the mechanism being frozen to the axle? I think you are on the right track with that idea. Very intuitive!

Hmmm, that is an interesting thought.  Maybe it has some type of pawls in it that allow it to be powered by the axle, yet roll free when its speed is greater than the axle speed.  I have now thoroughly confused myself.  I better think on that one after a good nights sleep.

Maybe it works like a David Bradley two wheeled tractor.

I have the very same dual wheel option on my Tiger PTD.  I've never taken a good look at them myself, but I know I haven't found their performance offensive.  Nice Tiger you have there.

Following out of interest...I think that is cool.

Hub question answered.  It is nothing more than a solid casting that slides over a square flange on the hub.  It looks like it was meant to have some slack in it and was heavily greased, but no moving parts or mechanical action to it.  I forgot to get pics.
