[davegsxrold929r]

i searched around but can not find anything ., for an 03 cbr600rr do you need case covers ??! like the gsxr does !!

2nd i am looking for some ride-height numbers for initial setup ., rear right height measurements and or eye to eye for the rear shock ??!  and for the front as well., with forks done by GMD if that helps., how much fork tube showing above the triples ., ?? any help would be great .,

thanks alot

Yamaha and Suzuki are the two that side covers are required on.

It's up to the tech inspector.  ::)

I was forced to buy a sidecover for my 92' F2 this year at Loudon. But, Tech never said anything about it at VIR. And it's not listed as being required in either rule book.  :-/ I was lucky a vendor had one there at the track.

No.  You don't need case covers.  Honda makes things right.  

As for setup, it's really up to your style.  We left the front stock height, and raised the rear by 4mm at the shock.

Fork work and overall setup by Suspension-Ed Kwaterski of Trackside Engineering

Rear shock - Penske 8660 - Again built by Ed.

I will be having the chassis optimized by Mr Matt Drucker of MD-Racing on his Kyle Gordis system within the next month...

[davegsxrold929r]

yes true it is up to each riding style ., but it helps to have a baseline starting point and work from there....

thanks that helps !!!

Did you buy a RR? You should know to just bring it to GMD! ;)

CCS required side covers on ALL bikes this season..pretty sure anyway.. was a new rule for 2003.

I think it might also depend on what brand tires you are running. I am on Michelin's, I have the Ohlins 9mm longer than stock with the front end 4 mm lower than stock. I haven't had any bad mojo with this setup. Be advised that the Ohlins is only good for +5mm "safely" without a longer stem installed on the the shock body. This modification cost about $75. GP

its not in the rule book, although it does say final determination rest with head tech. But I am sure I can make a pretty good case if you carry a rulebook around with you.

Style?  

I think style may have something to do with MotoGP, but not here.

A motorcycle is build with specific parameters to fuction as a street bike.  So, things like seat height are huge considerations.

Things like anti-squat are not.  Anti squat is related to the relationship between the swingarm pivot, the rear axle and the countershaft.  A specific angle of the swingarm is not enough as each manufacture has different length swingarms, the pivots are different distances from the countershaft, etc.  Throw in the adjustable swingarm pivot on the ZX6RR.

Additionally, if the bike doesn't "create" enough anti squat, you may think that you need a heavier spring.  This is a common problem on production based vintage bikes...but then again, in their original state they didn't have as much traction...another reason why production race bike geometry needs to be somewhat different from its street counterpart...we have incredible amounts of traction with race tires that are warmed up...you don't have that on the street.

So, GMD Computrack places like http://4and6.com measure a whole slew of points on the bike.  Optimization takes into account many of those things.  But additionally, they take into consideration the spring rates, which is extremely important.  I won't go into the details of what that is;  that's there secret.  

Dave, if it was done by GMD before, take it to one of the centers or at least contact one near you.  Community ideas on this one may just put you outside of the good point of the handling window.

 Just curios, if GMD optimizes the geomitry, Where do they get there number's? Rake and trail can be set at a specific #. but ride height, swingarm angle... Doesn't that need to be set on how the bike turns in(feels)?. I haven't been SOLD on this YET. All I hear about is all the sponsored riders that had it done.

it is a penske shock ....not sure if it goes out to 9mm longer !! but..

and GMD built the forks ., but has not setup/measured the bike., they want $$$ for that ., i am just looking for a starting point ....


and dave., i have done a sem on suspention . that they went through the rear swingarm angles ., etc.. 12.5% etc..

and i am sure the ride hieght will be played with !!! but i need a place to start ., that is not stock !!!

thanks for all the input guys !!
