Hi guys,
I have an '02 620 dark with the single rotor/brake set up on the front. i also have an '04 620 donor bike with the dual front brakes and want to upgrade my '02.
so is this the correct logic?
transfer to the '02:
-front brake lines and master cylinder/coffin
-front wheel with both discs
-either both calipers (or maybe just the new right one)
am I missing anything?
am I right in assuming that the '02 right fork already has the proper mounts to bolt the new caliper right up?
thanks in advance!

It should all fit. Although, unless you're having problems braking and/or are just looking for a mod to do, the single disk brake should offer plenty of stopping power.
Good luck! Post up picks as you progress!
Just swap the whole thing over as a unit, that way you won't have to bleed 'em.
Not that it's a bad idea to bleed 'em.
Stopping power is definately not an issue. I grabbed toooooo much front on my 00' 750 and ended up in the E.R. with the tail of the bike hitting a car who jumped out infront of me. I first thought the same. Why not get 2 brakes up front, I'll have more braking power. If your going for the look, then yes. But unless you plan on doing endo's, one is plenty.
hmmmmmm. Perhaps I need to do some more test-riding to see if the current brakes are adequate. I've heard others complaining that the single disc isn't enough.

+1. There was a thread on this same subject somewhere and one conclusion was that the savings in unsprung weight with a single disk is more of a benefit than any perceived increase in braking power by going to dual front brakes. My thinking is that the dual brakes will only provide a real braking advantage on the track where they will take longer to fade than a single disk setup. But of course they do look better, which counts.
The unsprung weight savings is significant with a single.
Pads wear 2x as fast with a single.
With some good pads, and a flush and bleed of the system, a single front would be good on a 620.
Depends on what you need, braking wise.
If you're a motorcycle courier in San Francisco, duals wouldn't be a bad deal. [coffee]
The bike rides better with the single disk. [thumbsup]

If you're a motorcycle courier in San Francisco, a dual sport and a bear suit (http://www.youtube.com/watch?v=Q3CzYw5-qdA) wouldn't be a bad deal . [coffee]
Fixed. ;)

I saw that dipshit on the history channel. He was attacked by a bear!! So he has dumped his savings into developing that crazy suit. It works ... kinda. when he tried to test it on a real bear....... the bear was so frightened of some guy in a crazy suit it ran off. [laugh]
oh yeah... brakes..... ummmm I like em' [moto]
BTW, did you get the "good" 4-piston brakes with the '04 or the cheaper ones (I don't remember if it was '04 or '05 where the bikes came with both)? I can't imagine switching to dual brakes and putting on 2 pad, 2 piston calipers. Seems like a waste.
If you got the good ones and you decide to stick with a single brake, someone with a 620, 695 or s2r will be interested in buying at least part of your set-up.
My '99 M750 only has a single disc. It actually grabs with more initial bite AND stops better than my 900SS.
