i am very confused and already did a search . also most aftermarket companies mostly make +1 forward in both standard and long travel setups.

so do i need a +1 forward setup since my frame is an 89. my goal is to go wider most likely a +2 but unable to get big name makers that produce a +2+0 setup .

pls help.

you can do either depends on what you want to do

the +1 will move the weight of the bike forward a bit making it harder to wheelie but more stable

Lonestar still make standard travel +2" and LT +3 for the 250R

hey beerock,
i will use it primarily for mx and occassional flat track racing. so will
this make the quad handle differently than if i get the ones that are not +1 forward. based on the search i did here, the 88-89 geometry is best for the type of riding i do so if i get +1, can you give me an idea on how it will handle e.g. on jumps, coming into turns, wide open straightways ?
thanks,
joey

well, I can pretty much say i probably have one of the most unique setups for a R in terms of width/length

my front end is a +3+0 pro trax
most have +3+1 and narrow frames

I have a Laeger fliptop stock geom frame which makes the front end wider then a narrow pro front end laeger my front end is 52 wide on the bottom of the tire and about 47 on top of the tire due to my camber setup. a narrow frame is around 49" wide on bottom of tire, 47ish on top.

my rear end has a 1 3/4" shorter swingarm compared to a 86 swinger and 3/4" shorter then a 88 swinger. and measures 50-51ish wide

by shortening the front and rear my bike is 1 3/4" shorter then a 88 swingarm +1 front end which most all R's are and 2 3/4" shorter then a 86 setup.

being wider/shorter then most it translates into a fast turning easily flickable R the shorter swingarm allow you to tackle the whoops faster the wider front end also complements this

I know it will be pretty hard to find a 3/4inch swinger and a -arms that are not +1

it sounds like for what you would be doing the setup i have would work well

if you cant go that route , the 88 swinger is fine with a +3+1 front end but it will not turn in as fast and for TT thats an important thing, alot of people have short swingers just for tt, like -3"

i hope this helps you get an idea of what you want.

Beerock's right with all his info. Keep this in mind, all the chassis' are the same when it comes to mounting location of a-arms. The mounts were NOT moved forward on 88-89 models. If possible, take a measurement from the center of the swingarm bolt to the a-arm mounts on an 86-87 and an 88-89 chassis. They are the same.

So did the 88-89's just have a -1 swinger? I always thought the whole geo was moved faorward an inch. Swinger 1 inch shorter, a-arms up 1 inch forward. I had a -1 houser swingarm and houser +1 forward a-arms on my 87 250r and really like the geo, but I thought it was the same as a stock 88-89. Thats what houser told me it would be anyways.

yes -1 if you had a 86-87

see the 86 swing arm is +1 comarped to an 88-89 some people use the 86-87 for the length to keep the front end down

they also use the 86-87 to shorten or l them for TT or lengthen them for draggin since they are made of steel the 88-89 oem swingers are aluminum and you dont want to really play with it.

i know its kind of complicated because they changed the length and the front a-arms as well so it just throws something else into the mix to make it harder to figure it out.

like i said it all depends on what you want to do.

I have both +3 +0, and +3 +1 Laegers pro trax front ends, for MX I like the +3 +0 setup in every situation over the +1 forward arms. The bike just fells more responsive to me everywhere. The +1's are suppose to help with traction and the longer wheelbase should make it more stable in the rough stuff. I think all the pros back in the day ran the +1 forward setup and the wide (stock) lower frame rails (where the arms mount to the frame). I think it all boils down to personal preferance.
