newer usd fork like 06-09 to gsx750 1981

How much work is it to make it work? = )

The crown axel needs to be modified? Or just change bearings and the bearing track?

Thanks = )

Some of us re-use the original to thw frame steering stem / axle .

In your case : the 1981 stem. 

You fit that to the donor 

In your case :  the "new" USD triple plates. Some fit without an extra fill in piece, some dont. 

 

Others use a bearing swap via Allballs or the such. All depending on the stem length of the donor.

Most modern stuff fits with just a bearing swop as Blubber said 

Steering stops will need adding / modifying 

Just be aware most modern stuff is shorter than what you may be replacing  and softer sprung 

If your planning to keep existing wheel then spacers bearing swop or custom spindle maybe needed and disc swop 

Lot easier if you use the wheel for the forks you intend to use only downside is most modern stuff don't have a mechanical speedo drive...

If you look thru projects section you will find / see what others have done

Along with all the above, keep in mind that you'll be fitting them to a bike that's @ 50kg or 8 Stone heavier than they came off. So spring rates and damping will be way way off, and that will affect braking as well as handling.

Thanks for info = ) I will use the gsxr1100 1988 wheels and breaks!

You'll need a lathe and a press.

Also, the stops most likely need to be modified, look into that before you damage the tank.

Got a 2006 GSXR600 front fork in my GS1000
