Toe-in adjustment

[turbofiat124]

This Bravo 110cc ATV I have. When going up my paved driveway, if I'm going a bit too fast and I turn the handlebar in one direction or the other, it want's to over correct itself. On grass, it doesn't do this. If that makes any sense.

I thought it might be because this thing has a live axle but I'm thinking the toe-in needs adjusting. Or at least one of the front wheels is kicked out too far. They probably just eye-balled these things when they left the factory.

I've got one of these tools but never had much luck with it.



I thought i might give it another shot.

So do ATVs with live axles need toe-in or toe-out and how many degrees?

Or just line up both front wheels and go with it?

Need to have a bit of toe out in order to handle correctly.

Check out the "Bump Steer Fix" under Gio. This might help.

Thanks I will check the position of the tie-rods before making any adjustments but I'm not sure if we are talking about the same thing or not.

When driving on grass (or in the field), the ATV seems to go straight even when I hitting a series of bumps even while going fast.

The problem is driving on pavement (fast) up and down my driveway with no bumps. I have to back off the throttle, otherwise if I just barely turn the handlebars, the ATV wants to veer off in one direction or the other. Has nothing to do the suspension compressing.

But you guys are saying the one end of the tie rod maybe upside down causing this to happen?

toe in is a stationery setting .... when the car is moving foward
the wheels are in line... toe in is to take up play in the ball joints
from the loads applyed when the car is moving...

bump steer... is wheel flick as the suspension compresses over bumps etc
from poor steering set up causeing geomitrey changes...

It works best on grass because thats where it was designed to be used..

when I wasn't rideing/racing motorbikes , scuba diving , flying micolights and a few other things I was building & racing speedway midgets..

"It works best on grass because thats where it was designed to be used.."

I agree with that statement BUT, having the ATV veer off in one direction or the other when riding on pavement indicates an issue with the suspension. Maybe folks smarter than me here could offer some advice.

I certainly wouldn't accept that type of handling on a ATV I owned and would try to correct.

I was thinking the front tires aren't lined up.. example the left one is facing left... and the right one is facing right or vice versa. When straight both are angled to the opposite directions and in a tug of war state... Don't know what they call that other then the alignment is out.

I know the rear axles on these seem to want to get out of alignment... one side of the wheelbase will be shorter then the other. Could see that not helping this issue any too.

I didn't know mine was off until I loaded it up into my trailer.. one back tire touches the rear gate the other is off the gate by a couple of inches. I think 2LZ posted a ratchet strap mod when tightening the chain to get the rear axle trued to the ATV.

One thing I noticed was the distance between the front wheels is more than the rear. For some reason my friend assumed the front had wider tires than the rears but they appear the same width. I haven't measured them.

He said the reason was it makes the ATV more stable and less likely to flip around turns for kids. I've never heard of that before. Does that make sense?

thats common... The axle with the widest track is the axle that will take command
the front axle is the axle that the driver has the most input into..

ok.. make sure your ale spread is the same distance from the front rim to the rear rim on each side.... this also helps the chain adjustment... next make sure the toe in is the same front of tire .. left to right .. and then measure the back of the steer axle tires .. make them the same distance... check you tube for how to do wheel alignment on atv.. these are just Chimese kids atvs... they do not need any extra toe in or toe out... make them the same... then it wil steer good... last but really important .... make sure the air pressure is the same in all tires as this will make the tire taller and bigger... casing it to pul side to side...

Yesterday I noted that the tie rods are positioned correctly as someone mentioned. I'll check the toe-in.
