Also would winding down the rear shock ( making it stiffer ) help keep the front planted? Any info would be sweet :wink:


Pulling the forks up through the clamps effectively lowers the front ride height and transfers weight from rear to front. This will assist in keeping the front down.

Adding more preload will also assist in keeping the weight forward as it will reduce the rear squating under throttle. Depending on what model 9 you have, a smarter option (assuming you have already set your front and rear sag????) is to raise the rear ride height. 2000 models on have an adjuster at the rear shock. However, just ensure that you don't make it too nervous by going too far. 24 degrees is a nice head angle for a 9. It turns nicely and holds a line once in the turn.

Now, there is something you can do to assist in keeping the front down also. Coming off the turn, Jam your outside foot down on the pegs and get your weight right over the front. Dragging a little rear brake can also help although I tend not to use it too much, others really hammer it. HTH

Mate as already stated - Throttle control. Mine has standard sprockets but if I snap it open in 1st or 2nd, sometimes 3rd it comes up. Just get on the throttle earlier and open it up smoother.

See where your axle block is sitting and look for how many notches you have left. You may need to get a new chain to get the wheelbase you need.

Most people dont think about it but when you change sprockets you are affecting the wheelbase unless you set it up on the same mark everytime.

u can also get those swingarm exyensions, but personally i think that a bit of a wank...

i still stick with the MOST important factor..throttle control...

Yeh throttle control is important but if you want to be quick you need to set the bike up so you can get on the power as hard and as soon as you can. If the only thing your doing is throttle control you will get left behind real quick as the guy with the setup bike will be away as your still feeding in the throttle. I am talking in racing terms though rather than just going to a trackday now and then.

Swingarm extensions are only for drag bikes really but running the axle block as far back as you can really helps things out, especially on ZX10Rs.

From what I've read most places you need to go up 10mm on the rear to get the 9's to perform better in cornering, both turn in & run out. Only down side can be tank slappers tho, so you may need to start at 10mm, test & see if you need to come down a few mm. This link may help:

im all for the throttle control option anything else is going to affect the handling especially on the track. longer swingarms and pushing the forks up threw the triples is all good for dragracing but theres no corners on a drag strip.......... :)

All suspension mate, and gradually on the throttle helps too and you be surprised at how much faster u will be being smooth rather than ham fisted. Look at motogp 200+ hp you'd think they'd be uncontrollable on the gas but no...

Well its been a while since I put this post up and found that raising the rear end had a huge impact on the way she handles and really helped keep the front wheel down also changed the way I was riding with all the track days i've been doing its helped with throttle control and roll on! I'm now trying to get a little wheel spin out of corners and a little powerlift down the straights! :twisted:
