Slingshot wheel in EFE forks

by **Captain Chaos** » Sun Mar 03, 2013 12:03 pm

Hi,

to fit a 3,5" GSX-R front wheel into the EFE forks:
- remove the bearings from the EFE front wheel, and take the tube which is in between them. Do the same with the GSX-R one.
- you will find out the EFE one is 16mm longer than the GSX-R one. It needs shortening 16mm.
- buy some bearings which fit in the GSX-R wheel and on the EFE spindle. I don't remember exactly the sizes, but you need bearings with the ID of the EFE ones, and the OD and width of the GSX-R ones. They were off the shelf in the local bearings shop.
- the tubes in the bottoms of the EFE forks are now too short. Make some new ones which are 8mm (each) longer.
- the EFE speedo drive will fit after a little bit of material has been removed. Offer it up on the GSX-R wheel and you'll see exactly where.

And now, with that nice 3-spoke wheel, it would be a shame not to upgrade the brakes as well.
The Slingshot Nissin 4-pots, and the later GSX-R models' Tokico 4- and 6-pots all fit on the EFE forks, 90mm spacing between the bolts. But the Slingshot discs are too large.
Now Suzuki had thought about this and launched the GSX600F in the late eighties, this bike has brake discs that fit perfectly on the GSX-R wheel and are small enough to accept the more modern calipers when mounted in the EFE forks. All it needs is some small rings to space out the calipers a bit towards eachother.
Use the EFE caliper mounting bolts, they are longer than the GSX-R ones.

Now you have an EFE with good tyre choice and better handling (17" wheel) and decent brakes.

I took discs from SV 650, 290 mm , all similar to the Teapot´s.
They seem to be too large ....

the teapot discs on my EFE are also 290mm, and it just fits. Very little space between disc and calipers.

*edit* the teapot discs are actually 289mm.

I filed some material away from the calipers, now there is about 1,5mm clearance , works well ... :mrgreen:

Captain chaos. Do you remember the thickness of the caliper spacers mate? By the way if anyones interested i got my bearings. 15mm id. 47mm od and 11mm wide 6202z i think.

nope, don't remeember. I'll measure this evening when at home.

If if remember correctly the bearings i fitted are 12mm wide. They're out of the wheel at the moment so i'll measure them as well.

thanks

My bearings are 15*47*14mm.

And the caliper spacers are 3mm.
