Title: GSXR fork conversion completed
Post by: kman0077 on April 18, 2010, 05:44:46 AM
I did the GSXR fork conversion yesterday on my 07 S2R 800. I used forks/brakes from a 2006 GSXR 1000 with 320mm rotors made to fit a S4R.

THE PROCESS:

1.) The forks slid right in the triples as several members have already found out. I kept my handlebar on rather than clip-ons because I like the handlebar setup.
2.) I had to space the rotors out so I cut the center part out of my stock brake rotors which was exactly the correct spacing I needed.
3.) I spaced the wheel on the axle by using 1 of the GSXR stock spacers and by cutting down the stock Ducati spacer for the other side.
4.) I then used some thick washers as spacers on the brake calipers to get them to fit the 320mm rotors (05/06 GSXR 1000 is 310mm).
5.) Some longer bolts (hardened, 10.9 and 12.9 rated) in the rotors and calipers from Ace Hardware bolted everything together (10mm x 1.25 pitch x 70mm for the calipers) and (8mm x __ pitch x 25mm bolts for the rotors).
6.) A brake bleed got the brakes feeling good. Used the stock Ducati lines with the GSXR bolts.
7.) 2 brackets were used to hold the fender on (simple aluminum sheet metal with 3 holes drilled in it). I love the look of the Monster fender rather than the GSXR fender personally is why I went this route.

THE RESULTS:
 First thing to notice is the looks, I like the gold/black forks on the bike along with the wave rotors. If my seat cowl ever comes in from Ducati Omaha, I think the bike will feel complete. Next, sitting on the bike, got the suspension sag dialed in with the stock Suzuki springs to acceptable numbers (woo hoo!). Took it out for a ride next. The brakes are SOOOOO much better. I actually did quite the stoppie the first time I grabbed the brakes hard (un-intended, I'm no stunter). So, the brakes are going to work out beautifully. As for the forks, they also feel quite nice. I no longer feel like I'm constantly bouncing around and the enormous fork dive under decel seems to be minimized now. I'll be playing around with the re-bound/compression this week but I think this is going to be a very successful mod for me.

FUTURE:
Since the sag numbers are good for my weight (186 lbs + gear) I will not be changing out the springs most likely. I know I can get some better springs of the same rate but I don't think they'll be necessary for this bike. I'll also have to wait and see if I can get enough adjustability out of the forks before I go re-valving anything. I've owned an 05 GSXR 1000 before this bike and I still have an 02 GSXR 1000 as my track bike and I've been happy with the stock valving on them. Now I know this is a different bike but it's not completely different. I have a track bike so I only wanted to get the Duc better brakes and to be able to tune my suspension to my taste, so I'm not likely to dump too much more money into it.

COST:
Total cost minus the brake rotors was about $275, So, very much on the cheap with some good ebay scores. One of my stock forks was leaking so I was going to have to spend some money on the bike either way.

Must be the angle of the photo. It's held on by 3 bolts on each side via the use of brackets. 1 goes through the fender, fork, and bracket. Another goes through the brackets and forks. And finally another through the bracket and fender. So you end up with 2 bolts going through everything.

Question were you able to position the forks at the same height as stock and still keep the the stock handlebars or did you have to slip them up higher?

Great conversion.
Yes more pics please.

FYI, keep an eye on those washers you used to space the calipers,
depending what you have bought, some of them can be very soft metal, and not exactly flat.
Might need a re-torque after a bit, but considering you do some track time I figure you'll do that anyway.

Keep up the good work.

I might have to do this, some gixxers have gold forks with black sliders...... [drool] and of course the upgrade over the crap stock forks.
