Need Help.... Ive done complete change over on my 99 r1. The project started with just rims then i ended up completely dismantiling everything.

Problem:
The rear rims bearing are much larger than the ones on my 99 rim. I believe i will need new spacer circlip etc. Are all rear bearings different by year or does anyone know if its only 99-02, 02-10 specific?

Has anyone measured exactly the different offsets of the rear wheel before running this way? There are slight differences I am fairly sure. How much of a diffence the sprocket or the wheel being out of line by 1.5mm on th bike makes I don't know. Iam going measuring all this precisely this weekend I have beed doing an other thread on this project here

On this thread you will see that there are cad drawings for both bst wheels, the offsets are different.

One important point to note:

98-99 R1's have forks which are 15mm longer than all the others. So for 98-99's only, if you are going to fit 04-06 forks you need to get them lenghtened (and yes 04-06 forks can be lengthened safely).

Otherwise you will have insufficient rake and trail and the bike will tank slap you into oblivion.

Fitting 02-06 tripples gets some of the rake and trail back but it will still be a head shaker - and a tank slapper if you run a taller 190 x 55 rear or a lot of rear preload.

Note this is for 98-99's only. Putting 04-06 forks on 00 and up is pretty much a straight swap.

Cheers for that but I am putting 08 forks on a 03 so they seem to be almost the same lenght, the 08 ones are about 5mm shorter so I am running them1mm under the yokes.
Now the rear is a lot harder, things just do not line up. The rear caliper off the 08 will not fit and when I use the 03 one the disc hits the caliper I have had to get a 1.1mm bigger spacer made for the disc side I havent tried it yet but I am hopeful this will do.

Sorry my post was a general comment not directed at your swap.

Righto , finally got my wheel conversion done on my 1998 R1 , had it all checked over by the local yamaha dealer (which I suggest everyone who does this do ) to make sure everything was done correctly and I dont go assing of my bike halfway down the road because I stuffed something up

Used 04 R1 front and rear rims , keep the standard 98 forks , just used the 298mm 04 r6 front rotors and spaced the calipers in 1mm to fit .

Rear used an 02 rear brake calliper and calliper mount with 04 rear brake rotor , had to get a longer brake hose plus the old one was buggered .

Turned out great , handles alot better surprisingly plus ity looks alot better than with the silver three spoke wheels.

Rest of pics are here

Adapters for what? Your brakes? I just used washers between my calipers and the forks. That spaces them in just enough.

Hate to bring up an old thread but does anyone know if you replace the brake calipers, if the brake lines are interchangeable? For example, if i change the rear calipers on a 2003 r1 to a 2004 r1, do i use 2003 brake lines or 2004 brake lines, and do they interchange well? or for example if i change the front calipers from 2003 to 2004, which brake lines do I use?

Thanks in advance
