“We all know the thrill of the hunt, scouring around for neglected machines in backyards and toolsheds. Peeking under windswept tarps, and the skip of a heartbeat when you see the outline of the infamous CB750 Supersport fuel tank in some dimly lit shed”. Dustin Kott describes it in such illuminated terms, and he should know because he has done it. Many of us have stolen glances into an open shed/garage door, hoping to find some forgotten beauty, but it’s only a lucky few who actually stumble across anything of note. Dustin Kott is one of the few, and this is his latest build: the 76 Ruby Red Supersport.

A perplexed original owner left in his wake, Dustin lost no time in getting the “boat anchor” bike back to the Kott Motorcycles workshop. Ruby Red’s design concept was to emulate what a bike manufacturer would have done 40 years ago – if Dustin had been in charge. The original paint was to be kept, and stock look maintained. If anything, the bike would lose components, not gain them. To round this concept out, a high polish and blue zinc plating give the bike a ‘new old stock’ finish.

Much thought and work has gone into the aesthetic of the bike during the build. The ducktail has been formed so keep the lines of the fuel tank flowing to the rear of the bike, where it envelopes the taillight assembly. A steel wire framed seat sits amidships, trimmed in leather hide bearing the brand of the cattle that donated it.

An electrical system of a Spartan nature is fitted to the bike, Kott Motorcycles ditching any superfluous systems along the way. The bare essentials of hi/lo beam, ignition, charging and running/tail lights circuits are all that remain. A lithium iron battery is mounted under the seat, along with solid state replacements for the regulator and rectifier units.

One part of the bike Dustin was not impressed with was the stock rear brake setup. Described by the builder as “very cumbersome and unattractive”, the stock assembly has been swapped out for an FZR mastercylinder and reservoir assembly. To help in the actuation of the uprated cylinder, a pair of handcrafted rearsets have been fitted, ergonomically designed to help with rider positioning.

It’s the Kott special touches that make the design concept come to life. An oil tank, manufactured inhouse at the Kott workshop, is used to “accentuate the existing frame lines and to essentially blend almost unnoticeably into the overall design”. The bikes rims now feature black oxide spokes, this idea has been utilised because the black oxide doesn’t change tolerances like powdercoat does, yet has more endurance than paint.

From a “boat anchor sitting in a dimly lit shed”, Kott Motorcycles has brought this Supersport back to life, while staying as close to the original design concept as is possible. In doing so, Dustin has produced a bike which will have us looking under windswept tarps and in open shed doors, because you might never know your luck.

    Exactly what we have come to expect from Kott: beautiful design expertly executed. I really love the tail section. The lines flow perfectly. The only thing I would change, and this is just preference, is the seat color. Black leather might better match the black pipes, wheels, and other details. Very nice bike.

    inspiring video!

  • You guys at PB need to do it this way every time (if you can.) That is, having a video along with the pics and article is perfect. It’s nice seeing the bike in the real world and not just modeling for us. If you builders out there are going to have your rides posted here, MAKE A VIDEO. It doesn’t have to be perfect, just something to see the bike in action. As for this video, CUT THE MUSIC WHEN IT’S TIME TO RUN THE ENGINE. I’d rather hear the bike than whatever song that was. With all that said…
    This is a good looking bike. Not too keen on the seat color, but that’s just me (and apparently revdub.) Great lines. I thought I was tired of CB750’s, but I guess there was room for at least one more 🙂

    • We would love to run a video every time and we do when we can.

  • Nicely done. I agree with everything revdub said and I second what Tony pointed out. And I’ll probably go along with what ever Arnold says. Good taste never goes unnoticed. I also appreciate the many, many hours of polishing the alloy on this bike. I’ve been there and have the black fingernails to prove it.

      As Manx says, polishing ain’t for sissies. However the fact that we agree on many things shows that I have major character flaws that have taken too many years to fully develop, and are unlikely to improve much with further aging. Who mentioned that there was beer here?
      Nice video of dinging tin , assembly, and rolling on the road. ald

      • arnold

        To steal a clever idea (moniker), he will be old and broken like us old farts lifting that motor in by himself.

  • Bryan Kerswill

    This is for me at least, has an urban cool about it. The fabrication has that home grown, one off look to it and is all the better for it. With a set of flatter bars – my back and wrists – and I,d ride this any day and love it. Great video too, really sets the mood.

  • Tanshanomi

    I guess I’m showing my age here, but the current trend of severely undersized seats just ruins so many custom builds nowadays. If I go back and look at classically proportioned bikes such as the Bimota HB1, Laverda SFC, and original Pantah, the tail pieces were formidable things, with enough spacial presence to balance the visual mass of the fuel tank. Even the stubby seatback on the Honda CR750 came up as high as the top of the tank. This one looks as though the back of the bodywork got punctured and has deflated.

    • Mike B

      If you follow the arc of the top of the tank from front to back, it picks up almost perfectly after the negative space for the seat, continuing through the tail piece. The line is there, it’s just not a horizontal line.

    • Different strokes. I got curious about the ’77 Harley Davidson XLCR, so I started looking for one to buy. You want a long tail piece, check this out.

  • ramon deathisbeautiful

    i like everything about hand made things especially bikes but the way they seem to try to romanticize things on videos like this kinda kills it for me.

    • The video was a little “artsie,” but I’d rather see it than not.


    Brilliant, well done.

  • Cliff nothreefifty

    Beautifully done, I have a couple barn finds and pasture finds that would be worthy of this
