Deep offset wheels

[New450r]

Do deep offset wheels help stable the quad in turns I dont want to do a arms or wheel spacers

[jro09]

it helps

[400EXracer74]

yea it will help but it will also increse bump steer

[Out_Sider]

the proper term is not bumpsteer, but it does make the bars a little more jerky upon hitting an object

A friend of mine had 4+1 offset (4 outside, 1 inside) and he bent a tie rod on his second ride with the wheels on. He was going through a whoops section and the tie rod just gave out.

from what i understand the 4+1 wheels (shallow dish) help handling by bringing the centerline of the tire more in line with the ball joint.

4+1's are 4 inside, 1 outside

unless he was running them backwards for the extra width.

why is bumpsteer wrong? that is exactly what bumpsteer is, you hit a bump and it causes a change in the steering due to bad geometry .

[Out_Sider]

exactly, geometry and tie rod angles.. the wider rims do not change that

get wilkin250r in this thread, he'll explain it 100 times better than I

[dn1911]

the wider rims are changing the leverage ratio ( i bieleve that is the term) wich is causing bumpsteer. bumpsteer is a general term that is used to describe any movement felt in a steering sytem of a vehicle when the wheels/tires hit an object, such as a pot hole or tree root, you get the idea.

you would want 4 to 1. It will handle alot better. I had 2 to 3 and there was alot of bump steer. Also it just didn't handle very well

FYI

Bump Steer is the amout your tires move towards the toe-out position as your suspention goes from top to bottom.

Measure your quad width when the front end is off the ground.
Then, measure your quad width when it is fully bottomed.

The difference in these measerments is bump steer.

Some quads like the DS650 have a huge difference, most others are much better.

i have 4+1 ofset rims and im fine...nothing gone wrong so far.

that is the same thing dn1911 said.........except you were being more technical. If you're getting a different width with the suspension bottomed, guess what......that will cause a change in steering when you hit a bump.

"Bump Steer" is more an effect of a geometry problem than it is the definition of a particular geometry problem. Bump steer is essentially any undesired input from an outside force on the steering system.

Those of you trying to limit "bump steer" to the change in the toe setting thru the suspension's travel are equally incorrect, as this is would be more commonly called the the toe-curve (not bump steer - again, bump steer is an effect, not a cause).

With this all in mind, yes - the tow curve will affect bump steer, as will offset wheels that increase scrub (e.g. heavily offset wheels).

all good points ... but 4+1 rims are 4 inside and 1 out from stock and also on some aftermarket rims. they are also available 4 to outside and 1 inside. we use these for ice racing etc. the 2+3 in my humble opinion are the best because they only move the center line of the rim out 1". the steering is not affected to much when you hit roots or rocks etc for trail riding. they add nice stability and still protect most of the caliper unlike the 4+1 with 4 to ouside.
