Just wondering if anyone has done a front end swap on their Thunderbird and if so, what donor front end did you use?

Kawasaki ZX-12R

If you want details, there's a short version and a loooong version.

 

[seumas]

I used the forks from a ZRX1200 on my Sprint. Like Crosstie's forks, they were shorter than the stockers, but they were the same diameter so they fit the triple trees. They also mount the 6-pot Tokico calipers.

Good write-up, cross.

Thanks Crosstie! Just what I was looking for.

ZRX1200R front end / wheels - very like the conversion seumas did. Spooner has also done the same thing. AFAIK I was the first to come up with / execute this idea. It works extremely well.

I race tech upgraded the front forks and used a GSXR Radial master cylinder to drive the Tociko 6 pots. at the rear I fitted a Triumph Trophy rear brake running on the stock ZRX rotor. I also substituted a TBS rear shock. It now rides, handles and stops like a sports bike. More pictures and details of the conversion can be found in my photo album.

The original conversion was to take the front from a T3 (95/96ish) Speed Triple or Daytona. You can upgrade these with 6-piston Tokicos or use Brembo calipers like I did.

Hi, not trying to Hijack this tread but. Did someone use a ZRX1100 front end? I could have sworn I saw one somewhere.
The reason is I noticed in parts unlimited fork springs for 98-00 zrx11 are listed the same# as the 94 Zx600e. I just found a complete zx6 parts bike for cheap. thanks.

ZRX1100 shoudl work just as well as the ZRX1200 there is very little difference.

However, the thing you want to double check is that the forks are the same length.

 

[MickMaguire]

The ZRX forks are a bit shorter than the stock Tbird ones, but it doesnt upset the handling it just quickens the steering and gives it a lower stance.

Yupp, I copied Mick :-D
Fantastic way to go!

I used the TBS front end.......but they are even more rocking horse do-do now than when I did it seven years back.

Nige.

Useful reading!

Old thread but this gave me a lot of ideas

Yeah, you should try to connect with Spooner, though he has dropped off the board since last fall. If you find him, ask him to stop in for a chat!

 

[panzaa]

Will do!

Do you have a separate "project-thread" for your bike?
Looks awsome

Nice to get some new ideas for the upcoming project

 

[fergrorke]

Harpooning this old thread. Is there a way to use ZRX1100/ZRX1200 while retinaing the original wire-spoked wheels?

 

[_ARCHON_]

Should be fine as long as you space the centerline of the wheel to the correct location, and verify brake fitment. Offset things can be made if you're off.

 

[_ARCHON_]

So, we have the ZRX11 and 12 conventional (adjustable) forks, and the ZX-12R (USD, adjustable), and I've seen a mention of a GSXR fork but haven't found the thread.

ZRX- not USD, is adjustable, bolts into stock TB trees, 6 pot double brakes

ZX-12- USD, adjustable, needs a custom upper tree and the stem pressed into the lower (and a shim), 6 pot brakes, shorter by 1"ish

GSXR- ???

Hayabusa?

T3 Striple - direct swap

Is all this right? Anyone have more information?
