Have Gsx-r forks, should I swap?

Hi there, been lurking here for some time but now I need some input from the more experienced sv crowd. I bought my 07 1000S in late july this year. A couple of weeks before that I aquired a gsxr750(k1) frame with complete front and rear end for cheap(it was basically a steal), the plan was to put the gsxr front on my project bike; a 78 Suzuki GS750, and I did.
But then I bought the SV and read all about the gsx-r conversion and how awesome everybody says it is but I've looked, and I've measured and compared the two and I've ridden the SV hard and the SV1000 fork is a pretty good fork isn't it? It's pretty beefy and fully adjustable. Is it really worth the work to swap forks on my two bikes?

The GS looks pretty good with the usd forks, but a part of me thinks that it should have the SV forks, both to make it look more period correct, and looking at retro musclebikes like the XJR1300, GSX1400, CB13000 and the Kawabunga ZRX1200 they all pull it of with the rsu forks. And besides the SV forks would be a substantial upgrade over the stock GS forks anyway and the i doubt the GS would be able to utilize the full performance of the gsxr forks...
Also, the SV is a sportbike, usd forks looks better on it. And I have a spare handlebar and risers lying in my garage so I could do the superbike bar conversion easily.

what are you're thoughts on this? This issue has been nagging me ever since I bought the sv
Sorry for the long read, here's pics to make up for it

I wouldn't bother with GSXR forks unless your SV forks are damaged. Simply re-working your SV forks is a lot less expensive, and the performance gain of GSXR forks over properly set up SV forks is insignificant. You're far better off saving the money that you'd spend on GSXR forks (and setting them up), and put it toward a good rear shock.

If you were to upgrade to GSXR forks on the SV, I wouldn't bother with anything older than 04/05. Anything older and you don't get the radial mount calipers.

I put " made to measure " Maxton rear shock on mine, £525 delivered and set the front forks up to match the rear after putting fresh 05w oil in them, 500cc per leg and its incredible.
I,m 225 lbs by the way,

Rick: I sense a contradiction here. You advise against swapping the OEM Suzuki SV-1000 forks for inverted (GSXR) forks but in another thread you are looking for a set of the latter.

How's that? What am I missing??

But I'm not spending any money on this. Just a night in the garage, swapping them over, I already have the forks... So I guess it's more a case of looks then... If the difference in performance is negligible

A crowd (majority?) of motorcyclists/people make similar choices.

FWIW, GSXR setup on SV, and SV setup on GS 'looks' like a double-win to me.

The older GSXR forks are too short. Even the k4/5 GSXR forks are a bit short, which is why there are extenders available for the 600/750 Showa forks.

No contradiction. I damaged one set of SV forks when I cut bambi in half, and built a bike from a bare frame, both of which were recipients of K6 750 forks. At one time I put a set of older forks on my naked, but went back to stock for a number of reasons.

A lot of my information and experience with suspensions and geometry were the result of trial and error. I'm just trying to save others from making the same mistakes that I already have.

Longhair does hate USD fork swaps...


That doesn't make the stock setup less worse. But considering it is a 7 year old bike, the oil in the forks won't resemble oil anymore and the rear shock won't have much nitrogen pressure left in it, plus contaminants in the oil... IOW, servicing it will make it less sucky.

IMHO, the rear shock is what sucks the most about the OEM setup. I'd clean the hell out of the forks, add new synth fork fluid, proper set of linear springs (for your weight) and a new rear shock. A Penske double clicker works better than a triple clicker shock from a newer super sport.

I don't "hate USD fork swaps", but what I've found through rigorous testing is that it's money poorly spent if not done out of necessity.

The best way to fly is as you (Tod) have expressed. Proper weight straight rate springs, proper amount of correct quality oil, appropriate valving, and replacement of the total crap rear shock.

Improving the front end by any means will serve to make obvious the deficiency of the rear shock, so you might as well include some sort of improvement of the rear suspension right from the start. A high end shock can cost as much as you'd spend on the negligible improvement you'd get from a GSXR fork swap set up right, and along with sensible stock fork mods will be heads above a slapped together compromise of assorted GSXR stock parts.

I was in the same position as you and could have done this for really cheap. I decided it wasn't worth the bother and improved the forks I had. You'll never get this bike close to a nice super sport that rails on the track no matter what you spend so (don't believe me, ride a stock Aprilia 1000 R model) I decided to maximize what I own. Nicer looks and potentially better front brakes are very enticing however.

Yes, and just as I have made up my mind along comes bikeexif and steals my attention with these fabulous builds by japanese company AC Sanctuary:
http://www.bikeexif.com/?s=sanctuary

They're pretty much the perfect look I'm after, a muscle bike which looks stock but still has more up it's sleeves than what is first apparant....
Greetings from the most undecisive man in history

BTW, I've been looking at fork extenders but can't find any for the 00-03 GSX-R 750 forks. Does anyone know if they exist?
Does fork extenders for the TL1000 and hayabusa work?

I don't think that anyone made them for 43mm Showa forks.
The Busa and TL forks are KYB, and therefore not compatible with 750 Showa tubes.

We had Showa fork extenders on our 07 GSX-R750 race bike. I am pretty sure they were supplied by Traxxion Dynamics.
