Radial Callipers

[Jt1200]

Hi, Anybody out there know if it possible to fit 2006 R6 radial calipers on to a 1990 FJ1200. I know that these will not fit as a direct replacement for the OEM caliper. Any bracket mod to fit the R6 caliper.

John, I've not heard of anyone making an adapter for radial calipers onto FJ fork lowers..... that said doesn't mean that its not been done of course.
FYI 2003 R1 gold spot calipers were the last of the non-radials that are a direct bolt-on...... not sure about R6 (which were usually a year behind the R1 in parts fitment - FZ1s were in the same boat).

Thank you for the info. I have been offered a set of R6 calipers free of charge- may be easier and less hassle to buy a R1 gold spot.

Fit the USD R1 or R6 forks and the radial calipers come along free of any additional fabrication!

John, I moved your question over from the Files section, where you originally posted it.

Please don't post your questions in the Files sections. We want to keep them clean and concise.

Thank you.

You're welcome John.

As far as I can ascertain, the 2003 R1 gold spots are the same calipers as the radials with regard to piston size, so in theory should produce similar braking results.
As Tim has stated and demonstrated, R1 forks fitted to the FJ will solve the fitting of radial calipers, just depends on the depth of your pockets!

I have gold spots on gen1 FZ1 forks actuated by R1 master cylinder........ single finger front brake modulation all the way to front wheel wheel stands if you are so inclined - not that I recommend it, but its possible!

Just what I need to throw me onto my face at the first panic stop.  :-)

Yes David, unfortunately the need for the odd panic stop is going to happen no matter where in the world you ride. But it is nice to know that you can pull up real rapidly when the requirement is there, and I'd rather be thrown over the front that way then the even more rapid deceleration afforded by actually hitting the idiot that has just parked right in front of me!

Harvey, I love the thought of your brakes, what pads are you running?

With all the talk of brake upgrades here little mention is made of pad choice, this can have a huge impact on brake efficiency.

I found just changing from standard pads to EBC HH sintered pads alone made a big difference.

Harvy is right of course.  Nothing beats a good set of brakes.  I was reminded of this yesterday.  While commuting back home, filtering through traffic, I managed to find an open space to accelerate a bit and get some distance between me and the cars that were soon to be behind me.  I was moving at a fairly good clip for congested traffic maybe 60mph, when I approached an intersection where the light turned yellow, and I still had too much distance to cover to make it through before it went red.  

Now, typically I would give little thought to this and blast through, but there was a black BMW to my right, making a right, and her wheels were moving ever so slowly, it seemed prudent to stop.  (side note, she ACTUALLY DID pull out, so I was right) So I took a quick look in my mirrors to make sure that no one was immediately behind me, then decided to stop.  It took a second or so to consume all of this information and I now needed to throw the anchors out in earnest to actually get the bike to stop in time.  **OK, I'll admit here that if I had been going slower, this simply would not have happened, but such is motorcycling -things happen quickly sometimes**

As I began to progressively apply the brakes with just two fingers, I was pleased with the bikes' braking, I really was.  I felt what seemed to be every inch in the front-end compressing, all the way down, my hands and wrists were now noticeably heavier on the bars.  I began to consider traction, about how warm the tires were, and scan for oil in the intersection.  Then, I distinctly remember feeling the back end suspension extend what felt like all the way.  I figure, if it were possible to put a scale under that back wheel at that time, it would not have weighed very much. As the bike came to a complete stop, all of the loaded forces, unceremoniously righted themselves with a lurch, which confirmed that my suspensions had indeed moved significantly. Now, if I had had 10-15 more feet to stop, I could have let off on the brakes some as I approached my stop, to avoid the lurch, which is something I do naturally, but there was just not enough room for smoothness, so the lurch was necessary in this case.  [edit: Note, I WAS using the back break as well, but in cases like these it's the front that doing most of the work.]

I have never lifted the back wheel on any street bike through stopping (stoppie) just does not seem like anything I actually want to do intentionally -pavement is hard after-all.   But this, and the handful of similar instances throughout my motorcycling career, are about as close as I'd ever actually like to get to doing stoppies on the street.  Interestingly, I have no compunction to do stoppies on either a motorized dirt bike or a mountain bike, just not on the street.

Anyway, I was really glad to have the good strong, progressive brakes that are on the Gixxer -braided lines, EBC HH pads.  I'll say this, on another bike, with inferior brakes, the front would have locked, or the back tire would have lifted, I'm certain of it, I was right at the edge of it, and the feel was what allowed me to get there. These brakes saved me from running into the back of that BMW, and/ or the pain to the bike and me , from coming into contact with the pavement.

Here's to being glad things are still shiny, and not at all bloody!

Beginning to realise that fact. I am going to go the blue spot calliper way. Thanks folks for all the advise that I have received through all the posts. Great forum
