Brauchi’s Kawasaki W650 – ‘JagdBobber’

Posted on April 6, 2012 by Andrew in Bobber, Brat, Rat. 27 comments

So, we’ve just had a sweet BM tracker. Let’s continue the Germanic thematic with a bike not made in Deutschland, but perfected there. And with a Red Baron theme, no less. It’s interesting to note that Germany and Japan have an intertwined engineering relationship when it comes to new automotive developments. For almost all the most important road safety developments of the last 50 years, it was the Germans who developed the technology and the Japanese who perfected it. Take ABS as a great example. An electronics system created by Bosch and then installed by BMW on their K100 in 1988 was the starting point for ABS on motorcycles, but it arguably took Honda and their current generation ABS system available most notably on their CBR1000RR to perfect it. Many a professional motorcycle reviewer noted that in their minds it was the first truly unobtrusive ABS system that functioned on track as required without sacrificing lap times. You can see a similar development path for other technologies such as EBD, seat belt tensioners, and traction control. So what happens when you feed motorbike through the system the wrong way around? Oh, don’t worry – the results are better than you think. Meet the JagdBobber.

“It’s not a cafe-racer, it’s not a ‘brat’ – it’s a ‘JagdBobber,’ that’s what I call a bike with cafe racer lines, clip-ons and bobber wheels,” say Lars Justinger aka the bike’s builder. “Or what might happen when a Harley WL and a featherbed Norton/triumph have a mating and this would be the bastard child. I would have loved to build something like the Garage Company low raked fours or the black Triumph that they did – just with 16” wheels. But since I live in Germany and we have TÜV here a raked frame is something they absolutely dislike and it would have never been possible to get it on the streets legally… and street legal was something at the top of my to-do list.

So I did research what can be done and what are the demands of the officials and in the end I decided to leave the frame as it is (except for some cleaning) to make it more easy. I wanted to have the chunky wheels and luckily I came across some wide yokes for a w650 on eBay… yippee! I got some shorter shocks, clip-ons and parallel to that I did some photos and started to design the thing on my computer. So before I really started to pull the thing totally apart my basic plan was ready.”

“The rear section was made out of a XS650SE fuel tank. Mostly because there was no possibility to properly bend and shape sheet metal. Resin and fiber would have been an option but I wanted to try to do it in metal. The welds were bad and I got the opportunity to use tin to get the thing in shape. My first attempt was a total mess; I did some research on YouTube – that helped. But that’s something I didn’t learn to love. To the guys who nail that down, respect!”


“In the end the XS750 tank hit the jackpot.
The match to the already finished
rear end was spooky”


“The fuel tank took ages to find. I think I tried at least 5 on the bike and maybe 7 on the computer. In the end the XS750 hit the jackpot. So amazing how that thing fitted in. The match to the already finished rear end was (and still is) spooky. And the lines fit to the frame as well. I had to fabricate new mount points to attach it to the bike.”

“Since I wanted to do most of the stuff myself and I had no spray booth available I thought of a paint scheme that looks OK not being perfect. So I tried to give it a used look. Rattlecan basecoat, then fingers, sponges, thinner, grinding; the good thing is you can’t ruin a used-look paint job. Stop when it looks used enough or if you’re gone too far just take some cleaner and restart. There’s also a little story behind the paint scheme. I used to ride on my red drifter to the shop. A guy there always said, “there’s the red baron again” and since my first motorcycle was red, the drifter is red – I adopted that for the W650.”

Beautiful work, Lars. For those of you keen to see just how Lars did it can follow the complete build on his blog, too. Das ist gut, ja?

  • Like the style, don’t like the paint.

  • HotelBushranger

    Looooove it! Paint job is perfect. Sehr guht gemacht Herr Justinger 🙂

    • Agreed. Tony Stark, yr nuts.

      • Yes, nice of you to notice. I’m jaded against paint like this because I teach college level painting and I see stuff like this ALL the time (on canvas, not bikes.)

        But let me qualify it. Comparing the paint to what is usually on a bike, it is very creative.

    put some real carbs on it and we’ll know you know what you’re doing…

    • Davidabl2

      The big 16’s&bigger tires on the 16’s (Avons?) make the exhaust pipes look very low at the stock it with the stock bike pic. By the way, I am experiencing something with a similar appearance with the 2-into-1 On my Kawi Drifter, after strutting it.

      A bit of an upsweep to the pipe, or a short extension with a ess-curve might be in order..or even doing both.
      I like the idea of the header pipe making a kind of detour around the engine. A little like they did on 50’s Harley’s, but in a much lless exaggerated manner… Especially nice on the left side of the W650..

    Really like the creativity with limited experience.  The bike looks like it was built to be ridden.  I might be inclined to put a skinnier wheel up front if it were mine, but that would be it. Great job.

    • Cballs01

       “looks like it was built to be ridden.”  …????? Really? With those balloon tires?  I don’t think so.  It looks like it was built to be parked and oogled.  I’d like to follow the owner on this bike and watch him navigate some twisties.  Maybe that would knock the stupid out of him, and give me some entertainment.

      • davmo

        Yeah, with “a skinnier wheel up front”

  • cagivarider

    With reasonable wheels and the silly iron cross removed this would be a veryvery nice W.

    Best regards

  • Cervantes8

    Great bike! How on earth did they do the paint??

    • Brauchi

      thx! – rattlecan, fingers, sandpaper, thinner, …

      cheers Andrew!

      • Lars – can we have any more info on the paint technique?

  • GuitarSlinger

    I do believe me likes this JagBobber look . Likes the funky paint as well . So yes some further info on the paint technique would be appreciated 

  • revdub

    I like that paint. It came out really cool. I may have to use this “rattlecan, finger, sandpaper, thinner” method sometime.

  • Alex MacPherson

    The paint is dope! Well done!

  • Asdf

    The closed-in side panel and the ridiculous tyres make it bottom heavy. It works very well. Coupled with the low profile but proper length and width tank it gives the  appearance of it being low cornering, with good attack angles. A good eye for lines, angles and aesthetics here. The stop light is a nice touch.

    The Iron Cross is cliche, old hat and politically suspect, though. Would look much better without it.

  • Ted

    very very nice love the style 

  • Lars Justinger

    1st rust protection from the rattlecan

    2nd rattlecan-gold (more or less completely useless i think) (pic 1)
    3rd rattlecan-red (pic 2)

    then soft sanding to scratch the red (and also to get some shine of the underlaying gold – but that didn’t work) and black paint applied with a piece of cloth (kind of rubbing it in, more paint on edges and corners where naturally dirt would gather)
    i did this twice on the rear – because i thought it had gotten too dirty and too dark – used thinner to remove the black; but kept the red
    ended up with that (pic 4)

    here’s the cross decal part one:

    then with white applied with a tiny brush (pic 5)
    it looked much too clean – so i damaged it with thinner and applied a bit of black just by rubbing it on and mostly off again – like a thin layer of aged dirt or so all around the decal

    here’s an intermediate result (still no “dirt” outside the decal)

    begginning of the fuel tank

    red base:

    ageing the tank and the rear to match them – since there was quite some time inbetween:
    applying paint with cloth (black and 2 tones of red and a mix of both in irregular order) removing it with cloth, fingers, little gentle sanding & scratching, repeat, repeat, repeat & repeat until i was happy; water based acryl colour.

    final paint without satin-clear: (pic 6)

    and with 2k rattlecan satin-clear: (pic 7)
    the the resin-based black i used for the black parts of the cross didn’t like the clear – it wrinkled. but since it’s just the cross it’s o.k./kind’a cool. 🙂

    i tried to get the look of an aged paint that was taken care of (sort of) – not too destroyed, no cracks; mostly because i wanted do do the paint myself, too (like all the rest; except the wheels and the leatherwork). and because i have no propper spray booth; something that could be done without a booth had to be done.

    • Beautiful. Thanks for the details, Lars!

      • Lars Justinger

         you’re welcome!

        • Don’t get me wrong, Lars, I do appreciate the paint and it looks good. Just in my line of work, it reminds me of how my students paint. Not to say that they could EVER apply paint like this to a bike, only that I have seen it before.

  • Cervantes8

    Thank you so much for your time! What kind of paints did you use? Once again excellent work!

  • Lars Justinger

    1k rattlecan car paint; 2k rattlecan clear (same brand to avoid chemical disliking)

    acrylic waterbased black and red for ageing and some resin-based black (the one that did’nt like the clear); from the home-improvement-shop 🙂

  • Cervantes8

    Thanks again!

  • Mackenziebm

    Does anyone else see the passengers foot pegs? I dont think theyre needed much

  • Eric Henderson

    Very kool
