    I'm using the stock XR650R master with a 320mm rotor, seems fine for how I ride it...I wouldn't try to out brake a gixxer into a turn, but it stops just fine for normal riding.

    What caliper LB?
    Do you know what size piston the MC is?

    I will be posting some pics soon.

    Stock XR650R caliper on a bracket to fit the 320 rotor, don't know the MC piston size. Probably on the 'net somewhere.

    Just got back from its first voyage farther than around my neighborhood. Put 40 miles on it today and rode all over Murietta Ca. It ran flawless. Better than expected.
    I got it up to 90 mph twice and it was a bit twitchy if you pull left and right on the bars over 40mph, but over all stable. It turns left and right very smoothly and transitions well. Obviously the handling is not as quick when flicking R/L as the 17" front tire was, but it was really controlled and solid. I notice it is very smooth even on the TKC80 front tire and the Kenda Big block rear tire. Between the longer travel and more plush suspension it feels even smother to me than it did in RT trim.

    The muffler is perfection. Too loud for most of the BMW crowd, but perfectly comfortable for me, a MX racing, 3rd generation Harley family guy. When on the throttle it is crisp and a bit raspy with pretty loud volume, but not painful at all, but when at cruising speed I could not even hear it...NO droning at all....perfect.

    I had 2 of my riding buddies ride it and both got on it pretty hard, I could hear them through their neighborhoods and they both loved it. Both thought it was a bit tall, but they both have shorter legs. For me the height is fine. I am 6' 0" with a 31" inseam and I can touch both feet very comfortably on the ground. One dead flatfoot and the other on the ground mid foot forward. If I really scoot forward and roll my hips forward I can actually touch flat foot on both. I am used to KTMs with heavier springs for track riding so single footing is my norm.

    The brakes are substantially better with the 20mm RT MC...rideable, but barely. I ride with big gaps and a VERY heads up attention right now and at very moderate speeds so as to not need to panic stop. {yes I know I just posted a 90 mph pass...but that in a very special spot I have with NO houses, no cross streets, a full fence along the road and a concrete culvert parralelling the other side...no cross traffic, virtually no animal issues...and no panic brake issues.:lol3 }

    Even though it appears no one is too interested in this build...:puke1
    I had a buddy notice that my forks were push up in the clamps about 14mm or so, I am just used to running them there on my YZ's that is where I set these. I also tend to run my steering head bearings on the loose side to keep my dirt bikes with a light steering feel. Usually finger tight.

    I came home and loosed up my forks, torqued down the bearing jamb nut, not even that tight just snug, about 1/2 turn and pushed the forks down in the clamps and no more shimmy when I wiggle the bars. 0
    :clap

    I put 25 miles on it today and man, I love it. I have a high front fender and the21" TKC 80 on so there is a little bit of wander on the Cali freeways over 65 mph as it tracks the saw cut lines in the concrete freeway. But on black top dead smooth and stable. Stoked!!!!!

    Here are a few of the custom footpegs and shifter arm....look at those aluminum welds :eek1
    That shot of the weld inside the footpeg opening {that usually centers the swingarm pivot}, that is like a 2" diameter hole and about 1-1/4" deep, try tigging that...my buddy rocks.
    There is also 2 bonus shots of my cafe bike :evil

    Very interested in this build!! I'm going the other way - I have 95' R1100GS that I am turning into a street bike. I'll start a thread for it later this summer. Your thread is keeping me interested and enthused until I can get back to my project. Thanks for the posts and pictures!!!

    Not that I am trying to sell on the boards, but I have the stock RT forks, shock and some other bits for the front end if you are interested. It is all interchangeable with the GS stuff. Forks are just shorter as is the shock. I also have the upper triple clamp, and RT bars.

    Thanks but I already have all that stuff. I'm using R1100RS shocks and foot peg plates and pegs. I also am using the side stand and center stand off an RS.

    So for anyone building a larger bike and concerned with brakes, the 320mm front supermoto brake is amazing.
    I have the SuperMoto caliper from Braking coming possibly tomorrow, but not sure if I am going to need....I will use it of course, it is paid for :D and the wife even knows about it :clap....but holy cow what a DIFFERENCE just the rotor made.

    I think I need to lower the front air pressure in the tire a bit because I can make it slide quite easily now under braking. I think the 32mm pistons in the coming caliper may add a bit more feel to the lever which I think will help.

    The bike is fully rideable now. It still needs some finishing touches on the fairing. I would to do a HD spoke kit before very aggressive off road riding happens, but they seem just fine so far and I do not plan on airing it out...on purpose :wink:
    I would like some hand gaurds soon and I need to start on my panniers as soon as I get back from Canada and then I am TAT ready....I think I will start with a run down to La Paz and stay with a buddy there for a few days and dirt it home.....

    I am REALLY stoked so far...better start than I thought and every day I adjust and fiddle and it keeps getting better.

    I am not saying the forks springs are perfect, but they are MORE than adequate for everything I have done so far. I have found that soft springs usually show up on whoops, big jump landings and hard braking. I have not flown it, yet, or hit whoops hard, but under hard braking, now that I can, it does not dive even as bad as my KTM 530 did.

    Now I want to ride somewhere so bad, but leaving tomorrow for a car road trip with the wife and kids to Canuckville for 2 weeks, so it will sit, but I am looking forward to getting home and putting on some miles!!!!!

    Following this, but it's way beyond anything I would even try and attempt. I just love the thought and engineering going into the build. Fascinating stuff, so well done on taking this on.

    It's a pity the 'poor-man's' HP2 bike died with BMW. There is (or was) a market for a stripped down oilhead a few years back.

    I would LOVE to get to ride a real HP2e to get a baseline on where I am at on my bike.

    I am currently working on a new clutch lever and perch set up. The throw on my MX bike set up is just a bit too short so before I left to Canada on vacation with the family I ordered an F800gs perch and a billet lever for that bike. It has the longer throw I need, it has the 10mm cable end I want, and it is a quality piece, but it has no hot start lever for me to use as a choke lever like I am now on my MX perch.

    If the clutch works out, it should fix my issue with how tight the adjustment needs to be right now and how far you have to pull it in to disengage it. Only real issue, the choke/hot start lever is not an issue to me, is that the cable is very different on the outer housing on the R1100 and the F800. The R11 has an adjustable bolt on the perch like most bikes but the F8 has a completely wierd set up with no adjuster and an outside centering do dad thingy madoodle so I am fabbing up something to fill in and adjust...

    Due to all the welding heat, isn't all the aluminum soft as butter which is why manufacturers heat treat their aluminum frames after welding them together?

    Right, they're shooting for a uniform hardness in the T-6 range. It's the quench after the heat that really sets the hardness, then you can check it with a Rockwell meter.
