50 inchs?

[blakefoote]

what offset rims do I need to get for my front to put the front end at 50inches on my 400ex? that is me on the right (duh) but Iwant to be at 50 or 49 inchs:ermm:

Don't bother with offset rims.

why do you say that?:ermm:

[FoxRacing81]

They cause bumpsteer, put unwanted pressure on balljoints and tierods, and expose your brake calipers.

well what can i do to get it at 50inchs then?:ermm:

[bdb24]

I had them on my 400ex when i bught them and i raced it twice and they bent

[blakefoote]

i was j/w b/c i think it looks kinda skinny....:ermm:

[luvmyex]

how about longer a arms???

[hondajoe05]

you could buy wheel spacers... but i've heard bad things about those to

arms are gonna be your safest bet tho

[400exrider707]

offset rims and wheel spacers will cause your quad to handle worse, and also offset rims DO NOT cause bumpsteer.

I got longer arms.....:huh

they do, longer leverage ratio on the spindle causes the tire to want to jerk more hence, Bumpsteer. a wider offset will cause more bumpsteer and make it handle worse, if you go the other way, get 4+1 wheels with teh wide part in toward the quad, it will actually handle better because teh wheel is closer to the centerpoint of teh spindle.

He means long than what you currently have. The only way to get a good 50 inch front end would be wider aarms. Flipped rims and spacers will feel awful.

[gpd005]

I've got so 2/3 offset wheel's i'd sell you. That will make you a little wider but it does expose your brakes quite a bit!

thanks for the lesson but get your facts straight thats not bumpsteer. You should probably do a little research. Bumpsteer is when your wheels are going through travel and as the wheels are moving up in travel they start to steer. Offset rims do not cause this. They might offer more "feedback" because of the leverage on the spindle, but it's not bumpsteer.

thank you for the lesson as well, but i know what bumsteer is, that is what i am getting at. when you hit a bump or some type of obstruction the suspention moves and the extra leverage caused by the offset wheels causes more feedback to be felt through the bars. it not ike the bars jerk going down a smooth road, but when you hit a BUMP, hence the BUMPsteer.

Bumpsteer is the action of the wheels being turned because of a bump. The wheels turn because of a change in the steering angles, Camber, Caster etc.

Feedback is what you are describing. It's caused by moving the wheels farther from the center axis of the hubs and spindles.



For the real question. Stock offset wheels and +2's should put you at about 50 inches. For +3's I've read you need 4:1 to stay under 50 inches.

the way i read it... youre both right..

"A basic definition of bump steer is anything that changes the direction of steering of a tire other than from the driver/riders input. This bump steer is caused by the extra leverage the rims have on the handlebars."

http://www.atvriders.com/articles/atvwheeloffset.html

paragraph 2, sentence 4 & 5.

thats not to say that i believe all that i read, but this makes sense to me..

[F-16Guy]

No, bump steer is caused by differences in length and mounting position between the steering linkage (tie rods, etc.) and the suspension components (a-arms, spindles, etc.). When the wheels move through the travel, the wheels will either toe in or toe out, with absolutely no change in handlebar position. You get "feedback" with wider offset wheels because there is more leverage on the spindle. You could probably offset that by adding a steering stabilizer. You can't eliminate bump steer with a stabilizer because there is no way to prevent the toe in or out during the suspension movement.

Thanks for helping me to describe that. Some people just dont get it and dont want to learn anything, they'd rather just post wrong information:rolleyes:

[insaneracin2003]

her is a pic of mine with ,i beleive,2-3 offset,it is the widest offset rim i can find.beleive me,the wider offset the rim,the more bumpsteer you will have,i know from experience.a steering dampner does help but if you want to go wider,get wider arms....

No, you will have more feedback. Say it with me; f-e-e-d-b-a-c-k.:blah:

what-ever it is,it jerks the bars more than normal...lol...thanks for clearing that upF-16Guy

[procircuit406ex]

stupid question but whats the purpose for offset wheels?:confused:

[insaneracin2003]

to give a wider stance,supposed to have more stability in corners and over rough terrain.......

[procircuit406ex]

thx ,are they worth buying?

[insaneracin2003]

i would say depends,for mx-NO,because of the fact that they put more stress on your ball-joints but for rec riding and no really big jumps than i think they are worth it....just my 2 cents

[procircuit406ex]

well i dont really jump like big jumps,the biggest ive hit so far is like 18 foot and where i ride theres not alot of jumps ,any way i ride ALOT of ruff trails,mud,rocks,and coal.help any????

screw ur balljoints out a little farther....

Balljoints shouldn't have that much slack in them! They only have extra thread so you can set the sides up the same.

haha...oh yeah i forgot about that....haha:devil:

[prepracing]

why do want to be 50" ? Is 50" even legal in sanctioned racing events :confused:

[400exMO]

Yes, it's the limit. For many motocross races, wider=better.

for some reason I was thinking it was 49" :confused:
