    Why a Vegan Diet? I'm stripping down the k75 and the direction of the bike will be a somewhat trendy street scrambler-ish K75.

    I picked the bike up on the other side of Atlanta for a seemingly great deal. The seller was a nice guy going through some crap and his bike had been sitting in his buddy's garage for years without being ridden. He gladly accepted my cash offer and after a quick chat and loading it into the truck it was mine!

    The day it came home:

    I have since learned the bike was originally blue. Somewhere along the line it was painted white. Probably the cheapest single stage white one could find because it started flaking off long ago

    The tear down continues:

    That's a pretty heavy exhaust....not like a cx500 crossover though...

    If you have followed the k100/k75 custom movement at all you know that the original sub frame does not make a tasteful modification easy. Some people have gotten away with hiding the sub frame. i decided quickly i would cut it off and start fresh.

    My buddy helping me clear the area for cutting

    and.......its gone

    The k75 has an aluminum tank, which means they look great stripped of their paint and brushed

    The stripping process is always a PITA no matter your technique.

    And now we are caught up. Lots and Lots more to do but for a couple weeks worth of work it is really starting to shape up.

    How is the rear shock going to be mounted? Looks good so far.

    As r60man asked...I was also wondering how the shock was going to be mounted. I think I got that figured out Today.

    Here's the inside bent to the correct angle

    And then both bent and welded up.

    Further support may be necessary. I'll have to see if it flexes with some force on it.

    I was thinking the same. I could see a gusset above the mount before the bend. Then one from the gusset to the frame in front of the mount to sturdy up front/rear forces.

    Gusset that shit... that has break written all over it.
    I'd probably box it, the esthetic is nice though.
    Since we got you here.... where exactly is planet Vego? And why can't y'all eat food?

    Boy Howdy.

    You need to take the back plate off the subframe and then make plates that slide over the tubes and extend to the shock mount. This still won't address the twist it's going to put on your subframe, but it'll keep the shock from breaking your leg if you hit a pothole.

    I've attached some lovely crayon-fab. :D

    Your imagination.
    Seems that a few have got on your ass. The upper shock mount will be fine.

    You may want to review your sub-frame geometry and its attendant mounting, though.

    Outta curiosity, now that you've sliced off the VIN # how are you going to address that issue?

    Some more bracing KIMG0372.jpg
    And off with the Speedo/ tach monstrosity

    KIMG0375.jpg

    The piece of the old sub frame with the vin on it will be recycled into the new sub frame somewhere.

    Disclaimer: this is not a rolling riding project. I'm not commuting on this thing with tabs and mounts loose and merely tacked. I'm well aware it isn't road ready at the moment.....I did pick "some assembly required" right?

    Some assembly required indeed.
    One question; not about planet Vego. Why welded and bolted subframe?

    Haha I'm not a vegan, I'm making fun of myself for being trendy doing a somewhat cliche build. Trendy like a millennial vegan? Sorry my humor didn't transfer.

    With the mounts welded to the frame and the sub frame bolted to the mounts, the sub frame is completely removable. This will make routing electrics easier. It's also nice welding and painting off the bike so overspray and sparks aren't finding their way to everything else on the bike.

    No no, it is. I also enjoy poking some fun at the picky little neck beards and their "cafe racers". So far I haven't seen one come back before their gluten free double frufru fluffy mocha latte with oak meal scrub was served up which makes me question the "racer" aspect some but it's all good. Most dont even understand the game or think I'm a mad man for burning ass to the corner of 6th and nowhere and back before my steak arrives but hey, we all can't be motorcycle demigods... Just me... but they still look cooler with their greased up beards with little cruelty free beads hiding up in there. Chic's seem to prefer that over my metal leg so I guess they win without even starting their bikes.
    It looks like the top is welded and the bottom mounts are bolted. Is the top bolted too? Just hard to see?

    Top mount is shown about halfway through the first post. I think I would add some redundancy to that mount. Those bolts are pretty small. Not sure I'd be able to trust it as is.

    You could probably swiss cheese that cross brace, but consider adding a strut that comes from the bottom of the bike similar to the pic of the other bike. 859327971_mhzkc-xl.jpg
    Would stop the twisting moment others were describing.

    I think I figured out the exhaust today, and the final seat mounts.

    Figured out why my front master was leaking....threads are stripped where the banjo bolt threads in. Someone must have went a bit hulk in the past.
