kz400 with a gxsr 600 forks

[50gary]

Yes, to adapt the GSXR forks to the KZ 400 head tube.
1. Press out the GSXR stem
2. Have a machine shop measure the specifications of the KZ stem write them down.
3. Have the machine shop duplicate the KZ stem from the aluminum GSXR doner stem.
4. Have the "new" GSXR stem pressed back into the GSXR lower triple.
I did just this operation last week for a DT 250 Cafe conversion using conventional 45mm 01-03 GSXR-600 forks. I then used new tapered roller bearings in the DT steering head tube. The reason this works quite easily is because both bikes use a 30mm lower I.D. bearing the upper of the DT is smaller I.D. so you can turn down the upper part of the larger diameter GSXR stem. Works well and I trust it more than welding the aluminum GSXR stem and getting it strong and true. The GSXR stem is robust and the finished wall thickness is more than strong enough IMO. Going from a very high HP heavier sport bike to a light weight 250 cafe bike I feel comfortable with the work. Next is to adapt a narrow 18" wheel to the wider forks using a single rotor, and the larger diameter GSXR axle. Just two cents of suggestive advise.
Cheers, 50gary

The narrow glide wheel is 3/4 axle and if you use the doble disk brake i think there is not to much of a troble to adapt .

 

[flaco]

And i am using the front forks of a 2003 gxsr doble disk .

Any updates?

 

[flaco]

working very slow sorry not a lat of time in hand and $$$$$$$$$.I make this seat form what you guys think ?

 

[biker_reject]

Time and money, brother, time and money! I know what you're going through. Seat shape looks good!

 

[flaco]

thanks man . the shape came from a cb360 tank that was rusty .

 

[flaco]

this is what happened to the tanks when the sealer is not apply correctly

 

[flaco]

well i am getting involve in too many projects and i did something on this one today i think i use the kz1000 front rim and have some one make adapters .

 

[flaco]

the diameter of the discs is bigger i need to make some tiny spacers and get longer bolts for the calipers . I need help ,it will be easier to use the harley narrow glide rim ?

 

[Big-D]

Reminds me a lot of my build...I need to get some updates done

[flaco]

nice build ,which rims you use in the front ? and which disc brakes ?

 

[Big-D]

Used KZ1000 Police wheel and 05 ZX6R rotors.

 

[flaco]

Good choice . I was thinking to uce the harley narrow glide rim , but dint know yet . Haw is the mono shock working ?

 

[Big-D]

Ya, in retrospect I still wish i would have went with spoked rims. The mono shock works awesome, although it has yet to see the road so I cant comment on the handling haha

 

[veaone]

Awesome work man. Cant wait to see this thing complete.

Thats more reason to upgrade the bike . I think the spoked rims are heavier
I think i need to star looking for the harley . I think i will duplicate your idea on the mono shock

 

[Big-D]

Good luck with it and keep the updates coming

 

[flaco]

well finally back to work on the bike here is the update

 

[flaco]
