    12E93E47-1BAC-460A-B89A-5B885FEBC21E.jpeg Hello all! Just wanted to share my k100 build, i got the idea to make a giant enduro and couldnt find any info on doing so. So maybe this will help the next poor soul who thinks a k bike would be fun offroad! Which is a terrible idea by the way, but i know learning the hard way is more fun!

    That’s a rad looking bike! Might want to protect the battery a bit though. Got anymore details on the build?

    Well, you have come to the right place for crazy idea's. Look up Australian scrapheap challenge.

    Got a few things finished up last night, hand guards on, and finally lengthened the kick stand, which is now a bit on the heavy side for the springs, so maybe revisit! 03672195-DF48-47A7-8B91-CD10B9B1F666.jpeg

    Also took it out for the first ride today to warm it up so i could change the oil, and turns out it rides alright! Minus the steering (this will be explained in a bit) but she really moves some ground...literally! 48B934C8-3962-458A-885D-9B9D6E2A0544.jpeg 06EF0F9B-26D1-4A0A-A8D2-E06E5393B5E2.jpeg

    FROM THE BEGINNING!!!!

    Okay so this started when i bought a klr650 from a gentlemen, took it home hated it, tore it apart and built it into this 45F31FDD-3406-45C5-B80D-AFE664CB1063.jpeg DA3A1CD5-557A-40FB-BE14-9E9D34E6C569.jpeg
    With all my time and money gone, and me still hating the klr650, decided to sell it! Previous owner sees and loves the bike now, not really in a position to buy though BUT he has a k100! We strike up a deal and i bring this home 46183DEA-8544-4449-A0A3-90A1D54AFD2E.jpeg
    Get it home, obviously first things first just tear it apart 3A2F73C8-23AF-434D-87BE-923DF48EE8AD.jpeg

    SO from this point a thought crossed my mind, i wonder if anyone has ever turned a k100 into a flat tracker, and i dont mean a street tracker or something, like a strait up race bike. I thought to my self that will never work, and i already have to much money into this bike to try.... so i did it anyway B48C0337-DEA7-4411-898A-B781F6FC1B96.png

    So it was a pretty silly idea, over the course of a year i just kind of tinkered with it, and when it was almost done i had another thought, i dont ride flat track, i ride dirt bikes & adventure bikes..... i wonder if any ones ever made a cool modern adventure bike out of one, something to confuse ktms on the logging roads, that wouldn't work, its a terrible idea ect. And now i have to much time and money into it, so of course i did it !

    Took all the parts off, first step was a front end, the bulk of the problems! So basically no matter what modern forks you try to use the frame is wide up front you cant get any steering angle out of it, i ended up with a 2001 husqvarna cr125 front end, the stem was alittle to long and to wide so i made 2 spacers, one under the lower bearings and one above the top, pretty small about 1/4” in height, then lathed about a 1/16 of the stem to fit the bmw bearings and bolted it on! Also had to weld around the stem because where the bearing sits on stem, there its wider then in the middle, think like an hour glass shape, wish i had pictures im sorry! But welded before lathed! 89872ED1-F3B2-4FB7-89EF-74965713A167.jpeg 10A241C7-6FE3-4CC4-AF87-128EA82E2561.jpeg

    So pretty much i ended up with about half the steering angle of normal bike, which really only seems to be a problem when your looking to turn around so far. But working on a solution!

    So I ended up using a yz seat, just because it was sitting there and i needed a seat, so plopped it on and bent up some pipe to build the tail 9963A48F-6B56-4A0D-9C9B-E9F8E5C48EC4.jpeg
