Swing arm angle WTF!

so I just measured my swing arm angle and with 9-mm of ride hight added I'm at 12.3 degrees , this to me seems kinda weird!( but I had to keep jacking the rear to get it to hold a line after apex) the ideal swing arm angle starting point for proper geometry set up is 12.5 degrees most manufactures set there angles flat to insure tire grip over anti-squat but this is HUGE # difference the 08 must has a very flat swing arm stock! my 04 was 3-mm away from perfect at 12.9 degrees! MMMMM what are you guys running for ride hight on your 08-10 zx10's?

Like you I'm running + 9mm, it made the world of difference in how the bike tracked the apex and mid corner. I blamed the steering dampener but I have to believe that the problem was in fact the rear swing arm angle.

People ask us why we ride a motorcycle. For those who have experienced the joy, no explanation is necessary; for those who have not, no explanation is possible.

Four wheels move the body; two wheels move the soul.

You start the game of life with a full pot of luck and an empty pot of experience. The object is to fill the pot of experience before you empty the pot of luck.

I've gotta set my 04 up for this weekend.

After setting sag, how are you changing rear ride height without messing that up?

I've got a Wilbers shock on another bike that is ride height adjustable which is nice. Too bad the rebound was all wrong and my tires looked like crap after only 3 sessions with wear on the trailing edges of the sipes near the edge.

Chrome and stickers are good for power. Why else would the big boys plaster their bikes with stickers?

I don't have a racebike-or even a track only bike. However, you have prompted me to investigate a little further in my setup.

Have a wheelie nice day!

Winter sucks.

I just started playing around with the rear ride height on my '09. I currently have it about 4mm higher than stock and was told by another race guy that it needs to be about 8mm at least on the rear. I'm gonna keep jacking it up and see what happens cause right now it's better, but not nearly what I think it should be.

I may not be perfect, but at least I don't ride a Suzuki.

Also, I found a cheap way to make the ride height adjustable on the ZX-10's. I paid $1.60 for a stainless jam nut and washer so that I could get inifinite adjustability out of it over using washers or the OEM shim pack. The nut and washer together are the same thickness as the stock aluminum spacer.

The nut is an M16x1.50 that goes on the threaded shock collar for those interested. Got it at Ace Hardware.



I may not be perfect, but at least I don't ride a Suzuki.

I think your on the right track, but I think Home Depot has the real answer. The support of the shock base isn't covered. The Home Depot route offers you 3 washers @ 3MM that full support the shoock base.

That is good info! Thanks bro!

Failure is only postponed success as long as courage "coaches" ambition. The habit of persistence is the habit of victory.
