Troy asks about his YZ lowering....
"i have a 2003 yz 125. i am about 132 lbs 5' 6" should i adjust sag first then try the link or a combination of both i have not really messed with the sag or adjust the suspention thank for your help"
Troy,
Hi. You should always set sag on any bike whether stock or with a YamaLink. Your bike is recommended at 3.9 to 4.1 inches.
Some inseam challenged riders put too much sag in to get their feet on the ground but when you do that it takes away from the overall net travel left to suspend you for that BIG hit...and you are riding too far into the progression of the travel. Meaning: yes, your feet can touch with too much sag but the bike will ride very rudely. Rude plus less overall travel is not a good thing, ya know.
When YZ 125 riders put on the YamaLink 1" lowering link, they have to reset sag because it has an increased leverage ratio. This makes the bike more plush on braking bumps and square edge, and it allows the rear wheel to travel further into its suspension arc.
Of course sag is dependent on having the proper spring rate. If you are too heavy for your bike to begin with (about 170 pounds is the average weight of rider that Yamaha sets their YZ125 up for) a YamaLink will magnify the wrong spring rate.
But if you have the correct spring rate and set sag at 3.9 to 4.1 inches, your 2003 YZ125 will corner better, get better traction and not wear you out so much after hours on the track or trail.
Hope this helps. Let us know if I can answer more questions.
Thanks!
