Title: '05 ZX6r Geometry
Post by: rotoboge on April 14, 2005, 07:04:28 AM
Can anybody out there give me some pointers
on the geometry setup for a '05 ZX6r? I have
heard from others that the rearend needs to be
shimmed as much as 15-20mm (dunlops). The triples are 2-4mm down...

I am riding the Michelin Power Race tyre though.
Thanks!

Easy way?

That's what I do.  My time is worth a lot to me.

This last trackday I used the following setup;

10mm down on the triples
15mm up on the rear, using shims

Handled very well on the short track we rode, 1.5 miles, but may have been slightly too quick at turn-in. Will adjust triples up 2mm on the forks this weekend. ;)

Actually, went back to the Dunlop DOT's for the
final set-up; 10mm down on the triples, up 3mm
on the rear with extra shims (total rear shim 15mm).

The Dunlops helped the turn-in for me, as their profile is more in agreement with my riding style. In Las Vegas this weekend, I will mount the new Dunlop Sportmax GP. ;)

Thought I would update this thread since it has been awhile I posted. I am still riding the Dunlop 209's and have the triples at 10mm down from the top of the forks, while the rear has been shimmed an additional 10mm plus the stock shim 6mm, for a total rear shim of 16mm. For those that would like to know. ;)

Turn in initiation and feel can work in different ways.  Sometimes counter to what you think is the right way.

You look at bikes around the paddock and one can see different things.

Fork heights can appear to be consisten, or, within a certain range.

However, internal modifications of forks can actually cause the distance between the center of the front axle and the triple clamps to be different even though the top portion of the exposed tube is the same distance.

Add to that the fact that swingarm geometry and rear axle placement will alter the front too...

Hi rotoboge,

I have just started racing in South Africa.  I'm running Michelin Power Race.  If you don't mind, what is your current setup and how are you finding it.

Thanks

Which Power Race are you using?  I do believe that what we have in the US is different what Europe has.  I don't know how the SA market works though.  

Last year, the fronts here were commonly known as PR1 & PR2, as per the markings on the side of the Michelin Power Race tires.

Super Dave,

I'm not too sure to be honest.  I have a look at the tires but couldn't find any markings that looked like PR1 or PR2.  What I did see is that the front is a SOFT and the rear is a MEDIUM.

What else should I look for?

Thanks

What you have would be considered "production based" tires.  I believe that they share the same shape and diameter of the fronts like the PR1 & 2 and the rears like the RP3,4,5.  

I know that the European market has a Michelin tire called the C2T, or something, but I don't know if that is what you have.  

Do you have a racing tire distributor that you get the tires from?  Tell me more, I'll try to help.

Now I know Dave is pimpin 4&6, which is good and all, but to just give you my $.02, setup is something that can't really be given over the internet.  There are far too many variables.

A good tuner will take the bike, tires, suspension and YOU into consideration in the setup...  Being as how nobody on here knows all of these variables for your situation, you're going to get a lot of different answers which in all likelihood will be worthless to you.

I doubt that he's shippin a bike from SA to the US.  

A recognition of the actual variables will give him direction though.

Totally agree, but the point was that if there's racing, there's tuners.  Get to working with one.  It's time/money well spent.

It's a place to start...

Hi Guys,

Thanks for all the comments.  I suppose that hooking up with someone in the pits and working hard at the suspension is the best way to go.  The problem is that I have JUST started racing.  I know very little, and anyone could tell me anything at this point.  What I'm trying to do in my first season is just get out there and learn a little for myself.  That's why any advice on settings and setup is a huge help to me.  When I get to a point where I can no longer manage without someone with a little more knowledge (and when I have more money  :'( ) then I will definitely make use of someone to set the bike up properly.  So please, keep the comments coming.

Super Dave, I can post all the markings on the tire walls, would that help.  Also, I had a huge front end problem during my first race meeting.  I'll start a new post.  Guys, please add your thoughts.

Thanks
