07 250F suspension

[PerrymanRacing]

alright im roughly 5'8 120 pounds and i was wondering if the stock suspension could drop this tho or if im gonna have to send it in for softer springs.

[markseaba]

you could try a lowering link if you just need it a little shorter

im not worried about hieght im worried about head shake bc i ride my dads 06 450f and i get real bad head shake. so im curious on how soft i can soften the suspension up on the stock ones with it still being correct otherwise im gonna end up sending it in for softer springs

Softer springs are not the answer ..

[weatherman64]

swap the springs yourself. you dont need to "send it in"

[GYTRthumper623]

yup youd defiently need softer springs and maybe a revalve

[PerrymanRacing]

well can i revalve by myself too?

im 140 and i set the race sag and it's been like near perfect since then

You need lighter springs. Try a .38 front and 4.0 rear. You want to get about 102-104mm race sag with about 30-35mm static sag. The 4.0 rear may still be stiff for you unless you are very fast.

factory connection has .37 and .39 front would either work and they also have a 3.8 or 4.0 should i go with the 3.8 bc im not like super fast but i do run top 5 in B class.

120lbs is really light for a 250F, I kept my son off the 250F until he reach 125lbs. It is hard to get the bikes right for such a light weight. And are you top 5 B Class at amatuer nationals or at local tracks? Are you going to LL's every year in the B class? If your are that kind of fast I would suggest .38 forks and 4.2 Shock. You can use one .37 and one .39 for an effective .38 in the forks. We did this all the time to get the right rate. The 3.8 shock spring will give you the 102-104mm race sag with real close to 35mm static sag wich is a good start.

My son ran from .38 to .43 forks last year and from 4.2 - 4.6 shock springs and he went from about 125-135lbs.

i got a new on and head shke aint that bad for me i weigh 150 and im 5 7

idk set ur front a tad softer and make ur back compress 5 clicks softer and ur rebound 2 ro 3 stiffer

[PerrymanRacing]

local tracks not nationals

[PerrymanRacing]

quick question, what are the specs on stock springs?

[gyd]

I think the 07 is .43 forks and 4.9 shock.
