    150/60 rears, 120/70 fronts. They fit a KTM Supermoto.

    So what makes it a supermoto tire?

    It's the proper size for Supermoto wheels, and it's very soft. 0197 or 0129 compounds. Neither of these would last very long on a lightweight road racer.

    What did you use for a front caliper set up?

    We cover the Southeast races for Bridgestone and Dunlop. I spent a little time in an SM bike around here. I even have a WERA SM championship, but that's a story for another day.

    Reach out to us, and we'll be glad to help.

    I bought a used Brembo 4 piston that came off of a 07 KTM 690SM. I milled my own relocation bracket. Also had to make a spacer to bring the rotor out some so that the caliper wouldn't hit the spokes.

    Did 2 days at the Corvette track in Bowling Green, KY this past weekend. The brakes are awesome.

    Nice bracket! to me, the forks definitely look long, since you lowered the rear already you've kinda gone backwards of whats normal, normally people start with the forks (lower and revalve) and lower the rear slightly.
    How much lower is the rear?

    Thanks! Well, my big butt is sitting on it, so it may look a little un-biased... I put a new link in the back that claimed to lower it .5". I didn't actually take a before and after measurement though. I have the forks raised up in the triples 20mm. Without me on it, it sit's pretty level. I'm not used to working with MX suspension. It has dual chamber forks. I did rebuild them with all new bushings, o-rings, seals and 30mm of spring preload spacers. I replaced the plastic "free piston" with an open aluminum type as well. A new valve kit is next on the list. It turned in decent this weekend, but I thought about lowering the front even more. I had a thought today of removing the fork legs and getting the fork tubes cut shorter. Is that how people normally shorten the forks? I've never removed a fork leg from a tube before.

    You shorten the forks by putting spacers in the cartridge to prevent it from fully extending. I can't give more details than that 'cause I don't dabble in bouncy bits and leave that to the experts. :D

    Upon a quick youtube search, is it as simple as getting shorter springs? I already have 30mm of preload spacers in there.

    Throw a GSXR front end on and just give me that caliper bracket!:D

    haha i understand you're sitting on it. mx suspension is long and has way more travel than you need so it's normal to shorten the forks 1-2 inches as well as stiffer springs.
    it's really worth it to spend the money and have the forks shortened and revalved for supermoto by some like thermos man, or dave at fbi etc
    Also, a common thing that catches people out while riding a supermoto bike is making sure they are far enough forward on the bike, getting as far forward as possible will dramatically help front end feel, and help you stand the bike up on exit.

    :Poke:And actually using supermoto tires and not something that's primarily designed for roadracing applications
