OK.....so I'm gunna weigh in to the whole pushing/swaybar debate.......
Pushing.....Understeer, is a result of one of two things, either too much traction in the rear or not enough traction in the front. With the 700XX I think the rear traction is overpowering the front. Honda know this and I suspect that is why the stock rear tires are narrower than the norm; to reduce rear traction.
I would expect a front swaybar would help with understeer but I also think this would adversely effect the front suspension in off road conditions. Probably great on a TT track as you are on a relatively smooth surface and you dont use all of the front ends suspension travel.
SRA quads are best off road without a front swaybar.......this is standard with most (all) off road racing vehicles; buggies, Trophy Truck etc:.....
We all know a wider front end gives all sorts of advantages including more traction in the front. Thing is, we usually make the back wider also. This is just made worse by using aftermarket tires that are wider and better than stock giving more traction in the rear.
In short, make the front end wider; more traction in the front. Make the rear end wider; more traction in the rear and that brings us back to the same problem of understeer again.
So what is the answer? As stated the issue is too much traction in the rear or not enough in the front. Front end turn-in traction can be greatly effected by castor. Castor is the angle of the steering pivot........the angle between the upper and lower ball joints on the front end of your quad.
If you could adjust castor and tip the front end forward a bit (top ball joint) this would result in greater traction in the first part of turning in to a corner. You can do this with alot of LT aftermarket front ends. Greater turn-in traction will result in the back end sliding a little easier during first part of a corner......power will keep it sliding.
At the same time I would not be surpprised if running a wider front end without spacers in the rear had the effect of increasing front end traction without effecting the rear......."trailin me" could test this for us he would just have to swap his trick rear OMF's back to stock or run no spacers and report results.
I think wider rear a-arms will make understeer worse (the suspension would be awesome) without doing something to greatly increase traction in the front.
