01-03 600 uses 45mm forks, and that's significantly smaller than anything else as old or newer. It might be possible to make those work - note MIGHT, you could almost certainly make them fit but safety would be an issue - but anything upside down is way too big.

There are good 43mm cartridge forks out there but problem is lower triple on sv is cast iron, not good idea to drill it. You have to look at its weakest part and see if safe or not.
By the time you get everything and do all work you can install cartridges in stock forks.

 

[Junkie]

Yep, a friend of mine installed 99-02 R6 forks on a 1st gen. He machined the stock triples out to 43mm. Who knows how safe it is...

 

[tovar]

I think top one is less of issue. Bottom one bends by just looking at it as is, never mind thinner. There is not much material in area where threads for pinch bolts are. It is also area with stress.

Does anyone know the front end details for the K9/10 GSXR 1000 ?

Particularly offset and fork leg diameters ?

I see that illustrations on the 1st page but what is the best/most accurate way of measuring offset and leg diameter?

tovar has a good technique posted on page 4

I just put straight edge against edges of fork tube holes and edge of stem hole. Measure distance and than measure size of holes and divide on two for centers. After that it is just adding and deducting numbers.

 

[tovar]

It is even easier if tubes are still in clamp, you just put straight edge against tubes.
If you don't have caliper to measure diameter of tube you use two straight edges, one on each side of tubes.

Flexible measure tape would probably be even better.

something like this..

Is that dog leash?
There is no use for that thing on motorcycle.

As is stock gsxr length is correct length for me .
Some will tell you stock sv forks are correct length.

I just did some measuring my 99 GSXR fork is 32mm shorter than my supersport stock fork. I want the bikes to handle similar. I saw Traxion has 20mm extenders. They both have Ohlins shocks so I want to get them as close as possible. The Superbike also has GMD adj. clamps does anyone have experience with those as far as adjustment base line?

 

[tovar]

Not sure how you measure 32mm when difference is ~20mm. Most people run stock forks pulled up so difference is not that much. You can put 10mm extenders in those.

This is too long but bare with me. I put a 06/07 gsxr 600 front end on a 07 sv650. After getting it all put together and riding it for a couple of days I was not impressed. The front end is not as stable as the stock one and has a tendency to dive in the corners. I have too keep extra pressure on the bars when it is leaned over. Overall its a big disappointment.

Now the questions, Will nicer bearings help? Anyone have a link where they got theirs? Does the top nut on the steering stem need to be torqued? What about the lower nuts that hold on the steering stem?

Last question has anyone posted what the settings are set at on their 06/07 gsxr600 front end?:dizzy:

Yes. If to lose or to tight it will handle weird.

 

[Junkie]

bearings won't help. if you can bounce the bike on the brakes and not hear clicking, the torque is probably reasonable.

what size front tire do you have?

 

[D'Ecosse]

Make sure that the ignition is not binding on the steering head!!!

 

[youkai]

The front tire is a 70 series. I also moved my ignition to the side so its not in the way.

- youkai -

Your problem sounds a lot like the one that I had with almost the same exact setup. For me it ended up being 2 things: 1. Steering head bearing was too tight 2. The ignition was binding on the frame neck.

I would suggest unbolting the ignition and laying it off to the side while you ride. See if that doesn't help.

If that doesn't help, leave the ignition to the side, and loosen the bearing adjustment a little, see if that helps.

If that works, bolt the ignition back on, see if the problem comes back, if so you'll need to grind away at it.

If none of that works, I got nothing. But like I said, sounds like the problem I had and I was super disappointed, once I got it sorted out, I still think that the swap is a little overrated, but much better than stock.

Thanks ill try that out when the temperature around here gets above 20
