The Definitive USD Fork Conversion for Sprints Thread

[dichotomous]

if you are lower, and less sensitive steering from the swap, wouldnt raising the tail a touch help both of those issues better than lowering the front and getting a shorter stand? all that would take is slightly shorter dogbones

Hi all useful info if you want to swap your forks see attached for difference in fork dimensions.

Well, I'm embarking on this.

I've got a nice set of pre '08 busa forks with axle and lower triple/steering stem.

A few questions though.

From the first post (out of which the pics are missing), I gather that the TLS top clamp would be the first choice because it allows for mounting of the key cylinder. What about the TLR top clamp? They seem more abundant, and I actually like the offset placement of the ignition.

Is there a way to retain the steering damper from the hayabusa?

Does the steering stem nut and associated hardware transfer over to the busa stem?

And lastly, besides the coerce fender, is there another option that would be a better look than that butt ugly hayabusa fender?
I hear the gsxr 1000 will fit after some mods, but I'd rather not start grinding on the forks.

Thanks.

Oh yeah, this is going to be a fighter project, because I trashed my fairings again...

Re the TLR clamp - you can only try - question is whether it has same radius placement of the ignition to clear the steering head - as well as radius, need to be sure it will not interfere with frame on right side when bars turned full lock to right, and become your 'steering stop'

You will need to use all the nuts from the Hayabusa stem.

To fit the steering damper you will have to make some kind of clamp for the fixed end at the steering head - questionable whether you will actually need it as you are already extending the trail; can't see it will be of any practical benefit, although perhaps you just want the visual.
i.e. if you don't feel need for it with OEM forks, you will need it even less with the 'Busa forks.

You can't fit GSXR fender unless you are prepared to hack the brackets off the fork bottoms. I have a link somewhere but if you are already firm on not cutting them, it is moot.

Thanks DEcosse, I'd appreciate the link to the GSXR fender mod. There is no way I'll be running a hayabusa fender.

Is there any way you could link some of the pictures back?

[DEcosse]

This is not the one I was thinking of, but the pics are useful to illustrate the issue of the top mounting bracket on the 'Busa forks.

Rather than taking the whole bracket off, as I can recall I think you can cut off the top part and drill/tap new hole for the upper fender mount
Suggest search for GSXR Fender on Busa forks on Google

Sorry, I'm not going to go back to rebuild all the posts again - most of it is fairly explanatory, but if there is particular image you need for clarification let me know.

I guess that I could throw in some pic's of how I made a '06 or '8 GSX750 fender work.
There is probably an easier way but it is what I did.
I basically cut off a section that wasn't going to work, made a flat piece of aluminum to fit and taped some new holes for bolts.

rad writeup. very similar to the svrider (where I'm coming from) info

So, here is where I am at with my project on the 06 Sprint, Using 2007 GSXR 1000 items.

The lower end has been completed, the wheel spacers, brakes, and steering stops made by Zoran @ TWF worked out great.

My issue now is my goal to put a LSL superbike kit top yoke on the bike. I was planning on re-using this existing unit (for an 05 GSXR setup) and milling out the stem hole to be 28mm for the new lower triple. But as you can see, I forgot how close the tank is to the stem.

Stock:


Anyone have any contacts for having a custom top triple made? I am currently talking by email with the folks at CNC topyokes in the UK. So far they said they could modify their current K7 offering to addresses the clearance issues I am having.


Might seem like a lot to do, but so far quotes are in the range of getting the Convertibars for the K7.
