Brake de-linking

Based on discussions in this thread:
https://vfrworld.com/threads/braided-brake-line-kit.61271/
I decided that I'd try and de-link my VFR, by replacing the front fork with a VTR1000 and the front brakes with some from a CBR954RR.

So, first I removed all of the old braking system.

Then, I started the conversion by removing some material from the bottom fork mounting points. (See images 1657-1663)

Next, I designed a 3D printed bracket, to be able to fit the VFR mudguard on the VTR forks. The brackets in picture 1715 has cut threads into them, but these will be replaced by melt-in brass types before I take the bike into use. (I will be sharing theese on thingiverse when I have tested the final version, if anybody is interested)

But now I have a bit of a problem when trying the CBR954 calipers with the VFR wheel. The caliper doesn't align well with the disc. It seems like I need a spacers of about 2.5mm to get the calipers to align properly.
Did any of you, that did this conversion, have the same problem?
What do I do about this? Can I just use some precision spacers in alu or stainless steel?
(To me it seems wrong to use spacers)

 

Nice work with the adapters!
I just did all this like minutes ago but opted a smaller fender. And my calipers are not show condition so shaved a little of them instead of the uprights.

Yes, you need to space the calipers inward. I used stainless steel washers. I measured them quickly and it is Moore than precise enough.
If you feel uncomfortable with this just sand them flatter on a surface covered with a piece of sandp
aper.

 

Thanks Kenneth
Nice conversion you did. I'm still using a VFR caliper in the rear and a CBR600f4 rear master, with the VFR reservoir.
I'm not too proud of the small brakeline jumper that I needed on the rear caliper.

I've thought about using some of theese spacers:

...but maybe I should just try ordinary washers.

Are you satisfied with the braking performance of the front brakes after the conversion?

Your rear spring looks nice, what type is that? I'm looking for a replacement too.

 

Thanks. I have alot of focus on getting the weight down, so the caliper had to go. And yeah, stealth level zero with that "jumper"hose as you say.

Those spacers would be perfect of course. But as long as the washer rests on the entire surface of the caliper you'll be fine. Remember it's 4 pistons so as long as the caliper is not rubbing it's good to go. Everything is self "leveling"
The correct way of course is to equalize the gap from caliper to disc so that the pistons have equal travel.

Also the vtr bolts will be to short to fully thread when spaced.

It has not moved at all yet so the braking is yet to be tested. There was alot on the plate so happy spring did not show yet.

I'm full matris dampers and shock now so the spring is not touched as it was ordered for my weight.

 

Thanks! I'll try it out
Two standard washers seems to allign ok...

Look closely at the front end. May give you some insight, I used a F3 front wheel from a 98 I think, used brand new EBC full floating rotors and called it a day, steers quicker cause the wheel is lighter, brakes better than my stock 93. Good luck and post pictures.

 

I de-linked an ST1300 using all the stock components except for a replacement master cylinder.

The easy fix is to use the donor cycle wheel and fender, but then your wheels will not match.

The next easiest fix is to de-linked with all the OEM stuff but for a MC changeout.

After that, different wheel, different rotor, spacer games, are your options. To me, those are way more difficult and time consuming.

 

I ended up using theese 3mm spacers:

The bike is now assembled and has passed the MOT check

 

Awesome. The way the bike should have came in the first place. Enjoy.

 

Thanks!
I have published the 3D parts that I made for this project on Thingiverse:
https://www.thingiverse.com/thing:6640501
If anyone would be interested

 

GREAT!!
That's the Gen5 as it's meant to be

 

I'm about to make the same swap (fork and calipers are on the way) and I'm going to make the same: couple of washers... et voilà

@MiguelDK : many thanks for your STL files

 

I have now added a lot more info on the Thingiverse page. More pictures, dimmensions on brakelines, a list with links of all the parts that I have used etc.
