Okay I understand that longer A arms help with the "twitchy nature" of the quad over bumps and jumps, also smoothing out bumps and jumps.
PLEASE correct me if I'm wrong

What I would like to know is do longer a arms affect steering feel and steering response and does the feel change the longer the A arms become?

I am looking at setting up a quad for all types of riding like trail, mx and flat track. I realise that to get a setup that covers all these types of riding will be a compromise but as I will not be racing for sheep stations it doesn't matter.

Do the same general principles apply with suspension set up when changing between brands of quads.

If no one can help with the specific info could some point me in the direction of some technical info about setting up a quad. I am new to quads and want to understand how to setup a quad, and how changing different parts can change the characteristics of the bike.

i never noticed much of a difference with respect to twitchyness, however extended a-arms will make the bike alot more stable and as a result make it possible to take corners, jumps etc quicker,

Hi zuki400, generall the same principals apply between the brands only that the specs for shocks/a arms will change.

The benefit of adjustable longer arms is that you can set your steering geometry more presicely for the application than the standard ones while also gaining the stability that comes with the extra width. with fully adjustable arms you can set caster (which effect steering speed) & camber(which efffect front tyre grip) which when set up properly will relieve you of your twitchyness in the front end.

thanks for the clarification pete.

which would offer the most gain if only buying one at a time, a steering damper or longer A arms. Could an anti vibe steering stem be installed before a damper or longer arms and still work as intended.

So many other thing to do to the bike that some things have to come second, but I would like the bike to step up the handling as the power steps up.

usually I say damper first but it really could go either way, a good damper will take away some of the twitchy feeling in the stock front end (and get rid of the nasty bump steer) but new arms set up properly will do the same and give you more stability. probably because of the kind of riding you want to do I woul dreccomend the Arms first.

An anti vibe stem will do it's job whether or not you've got wider arms or a damper on.
