ZX-10, Some Weights and Measures

Took some measurements while I was replacing front pads.

Now I know why bike was so good out the box.

For my 230, suited weight, the only thing I adjusted was max pre-load on front forks.
Haven't touched dampning on front, or anything on rear.

Front has 7 clicks off max compression dampning

and

has 8 clicks off max rebound dampning

So now:

Front Sag: Zero wt. to on ground, no rider : 16 mm

Total Front Sag : Zero wt. to 230 Lb rider on. : 27 mm.

Rear Sag: Zero wt. to on ground. : 12 mm

Rear Sag: Zero wt, to rider on : 22. 5 mm

**************************************************

OEM front wheel only 2 3/4 LB heavier than BST Carbon Fiber.

Thinwall aluminum ?

Total weight with tire and disk rotors: 24 3/4 LB

BST with same tire and same weight disks: 22 LB

**************************************************

Will be interesting to weigh Exhaust can

i'm bloody impressed with the wheel weights. the BST's are full carbon, right?

makes ya think when u realize that most of the weight is in the tire, and not the wheel. does tire weight differ between manufacturers/models?

Could be some variation in tire weights.

The ones I compared should be close.

ZX-10 wheel had Dunlop 218 Sportmax

BST Carbon wheel had 208. ( Full carbon wheel, aluminum hub. )

How about the rear wheel/assy?

How do ya rate the bike now that it's a lil more broken in?

Haven't had reason to pull of, yet.

The area around sprocket spindle does look compact and light.

Bike is doing good.

Have close to 800 miles on it.

May run quarter mile tomorrow, or next week.

Thanks very much for the suspension figures.

I have been saying for some time that my impression was that the bike's suspension is set up for a 250lb rider based on its outrageous spring rates reaction to 170lbs. Your numbers seem to affirm my worst fears....regular sized riders will have a mandatory respring in store (though most may not even know any better or care). I know some said its for a 150 lb hyper fast guy, but having valved a few of those forks on the 03 1000, I didn't see that being likely.

Oh well, very cool for you big boys, finally a bike you can just ride with out it wallowing all over the place.

For those curious about the rear wheel weight. RRW weighed them in at 31.0 pounds. For reference they weighed in the front at 25.0 pounds. No indication of the scale or margin of error. The big surprise was the Honda had the lightest wheel set, 1.0 pounds less than the kwaker (1.5 less up front and .5 more in the rear). The zook posted the heftiest set with 3.5 lb more than the kwaker.

I had my pre-load maxed out and dampning was probably about mid adjustment. A 170 lb rider could probably run front preload middle to minimum, and take a few turns off rear shock., to get desired sag.

Do you recall what your front sag was prior to turning the preload up? If I remember right, you dont get more than 7mm of adjustment out of them, but my memory is pretty spotty

Out back, if it already had 12mm of static, then the static would be too much by the time you got to a reasonable amount of sag with a lighter rider and sacrifice a bit of geometry to get there. Current numbers you got pretty much say its a great race spring for you and riders in the weight range.

You do have to hand it to the manufacturers responding to the demographics.

Personally, I'm gonna go all the way through breakin before setting the sag. It's a lettle bit soft right now for my weight, but that's ok, not pushing it very hard at all right now. So, once I get the suspension sag set, then adjust the headlights, I'll be ready to go. Man, gotta tell ya, I did almost 100 miles yesterday, every little bit helps.

Don't remember the prior sag adjustment. Adjuster was at mid adjustment, as most new bikes are. I think total adjustment from minimum to max is somewhere around 12 to 16 mm.

Probably best to just adjust rear for total sag, with rider , or 20 to 25 mm. There should still be a reasonable amount of static sag of less than total sag.
