Hate to sound like a rookie, but "sag" is what? It sounds like something to do with ride height. How is it measured?
I'm doing the BBR spring thing to my sons TTR125 on Wednesday. So I'm trying to bone up on the process. He's 12, and 5' 5" weighs about 160 in his gear.
To further complicate matters, I need to make sure we get it dialed in just about the first time. He's gonna get to be in his first race on Saturday. The REAL bummer is we've been going to the track every week for quite a while, he's gotten used to the suspension he has. I'm hoping it will still fly well, he has a tendency to fly nose low because he chops the throttle before he leaves the ground. (I'm working on it ):)
I've been racing stuff since I could drive, and this is his first motocross race. (Proud dad is pretty excited for him). I may not even race, just so I can help out if need be. Daughter's first race on the xr50 as well. I'll be a busy guy this weekend.
Thanks for the tips,
Bob
