Anyone know where I can get a top drop triple for an 03 gsxr 1000? Looking for something like the CBR 929/954 has:
Drop triples
- Thread starter silverbullet132
- Start date
+1 which will allow fork lowering without having to also lower your clipons/handlebars

Can't seem to find any for the 03 1000 forks, the ones I did find are $450 (50mm/75mm).
If I could find some anywhere from 1/2in to 3in for cheaper that would be great. (the forks are not going on a gsxr)

Which will allow changing the steering geometry trail to being dangerously twitchy. PhD engineers have nothing on some guy in his garage.
If you are going to do this, read up about steering geometry and install a steering damper. This mod could easily induce a speed wobble. Those are fun.
I have no first hand experience tuning GSXRs but I know that using fork cap extenders and raising the front of the bike is quite common for them.

dropping the forks in the triples, aka lenghtening the front suspension increases the rake which leads to a more stable, lazy geometry. Hence why cruisers have this steering geometry. Raising the forks in the triples aka shortening the front suspension changes the steering angle to the twitchy, responsive, headshake inducing stuff without a corresponding drop in the rear.

This is for my project bike, a 78 gs750. Stock forks are a bit over 31" and these are 29". That combined with changing the 19" rim to 17" drops the front end a bit more then I would like.

a 929 triple is gonna give you less than a half inch. Not enough to bother. Fork cap extenders, or longer forks are a better idea.
Or have a machine shop mill up a custom triple with 2" deep pockets large enough for 50mm fork tubes hanging below the top face.

Lowering the forks, in turn raising the front of the bike, will actually make it MORE stable.
As caboose said, no personal experience, but have heard it to be very common on GSXRs of various years.

Anyone know of anything? 929/954 uses 214mm spacing the forks I have use 207mm.

Take the one you have, and have a machine shop cut the centre out.....raise it as much as you need, and weld dropped wings onto it, so the centre can be as high as you need it, and the fork clamps much lower. If the trace a jig, and then re-assemble and weld it up back in the jig, there should be no alignment issue.
I have dreams of making a resto-modded 1981 Katana with modern wheels and brakes, and this is exactly what I would do, otherwise the nose of the bike will be dangerously low as modern forks are too short

GSXR1100 forks are long enough, especially with 929/954 triples. I picked newer forks because I wanted radial brakes.
Will talk to a few shops to see how much that will run me. Any recommended shops?
