120 tire effect Bike Geometry
Posted September 03, 2013 - 02:11 PM
So I have been running a 120 tire on my wr450 and what I have noticed is that it corners great but the back tire seems twitchy or spinning out a little to easy.
So I was reading about suspensions setup etc and was thinking. If the tire is taller should I be moving my forks down? Is this an adjustment that should be made when going to a bigger tire then stock?
I'm thinking if I raise the forks slightly I can get a little more bite and stability out of that back tire
And hopefully keep some of that turning.
I have set my a static and race sag and done a few things with compression and rebound on the rear.. It's better but still room for improvement and this might be an easy way.

Just because it's a 120 doesn't mean it's taller.
You have to check the tire co's website to confirm tire diameter.
And yes it will absolutely change your steering geometry. I used to run the Dunlops cause they were always taller, making my Honda turn better.
Heck, just going from 4 ply to 6 ply in the rear will make it turn better, but get less rear traction. A common desert riders problem.

The tire ratios and carcas numbers are not including the knobs.
The only way to know is the read or measure the actual.
