Custom: Super Motor Company Salt Shaker

Sometimes you start on a bike that along the way gets bigger and bigger ending up as a totally
overambitious project. We did start such a project over a year ago, a small capacity racing
bike, that we just could not finish due to lack of funds. Carbon fibre this, Chromoly that, 3000
euro here, 2000 euro there, we wanted the lot. Stoner once said to Rossi: “Your ambition
outweighs your talent”. In our case the ambition outweighed the wallet.

Back to square one. What to do when you have a Super Cub frame laying around, a tuned and
flowed 22 bhp 150cc engine, racing tires, rims and other bits and bobs? Turn it into a ‘non’
run of the mill city sled! The inspiration ranged from pre war JAP speedway bikes to post
Nazi NSUs. Add a touch of Bonneville salt and a sip of Bergringrennen beer and there you
go…

We started off with chopping up the frame, the fabrication of the ducktail and welding a
tube between the headstock and the fuel tank. This tube now functions a 250ml reserve fuel
tank. Most time was spent on the prep of the frame. Three full days of grinding, sanding and
priming. The frame was sent off to the painter, and swinging arm and rims to the powder
coater. Beforehand we knew it was going to be a waiting game since we got a really good deal
for both the painting and the coating. It’s ready when it is ready so to speak.

But still we had lots to do: the nitty-gritty stuff. Brackets, brake cables, clutch cables, throttle
cables all the little parts that had to be made to measure. Lots of work for things people will
really not notice. Next up was a military spec wiring loom. Never knew how much time you
can spend on such a vital part. It’s either right or wrong. No in betweens. In some lost hours
we made a custom seat pan out of glass fibre, got some race foam which we shaped with an
angle grinder and with some gaffer tape we made a pattern for the leather upholstery. And
then off to the 88 year old grandma to stitch the leather pieces together. Grandma loves doing
seat upholstery. She‘s done dozens over the years and she is good at it.

When we got all the parts back after a few weeks the assembly was pretty straight forward.
Within a day the whole bike was together. The last and most vital part was still missing.
The exhaust. And we definitely wanted a JAP style pipe on it. And this had to be made from
scratch!

A company called Shipping Tools in Zaandam, basically an Amsterdam suburb, quoted 50
Euros for one and 70 for 2 exhausts. Good deal…but let’s wait and see. After many hours of
fitting, adjusting and tinkering the exhaust was ready. And beautiful it was. We paid 50 for it
but the offer for a second one was withdrawn. Quite understandably so, because the guy did
spend some serious hours on it. A second would now cost us 150 euro. Which I think is
still a bargain for a hand made stainless steel exhaust. I strongly recommend them if you need
some tubing bend or welded in the Amsterdam area. Their TIG welding is spot on…

In November the bike will be send off to Milan (Italy) and will be shown during the EICMA
show at Officina Mermaid, the Italian distributor of our Super 120s.

If you want to see it in the flesh and running you might bump into us next year at the
Bonneville Speedweek. We are planning to do a few runs on the salt flats. We might even
challenge the class record. You’ll never know…

    Nicely done, men! Super indeed…

  • Clark

    This is quite nice looking.

    The bicycle bars and fatter tires are a great look.
    The duck tail really should go into production!

    Give me that motor in an all black super cub.

  • Gene

    That… actually looks pretty damn rippin’. And I hate customs.

    It doesn’t look like a dining room accessory, it looks like it could get out there and kick ass, unlike most customs.

    Good job!

    That looks like a hoot. And a stylish hoot, at that.

  • Scott-jay

    Nice, nice; want to ride it.
    Reborn fork & blue body-frame, perfect wheels.
    Fit between bars & fork ‘looks’ fragile.

    Really nice, great job, love it.

  • dimitri@supermotorcompany.com

    Thank you all for the enthusiasm. Yes the bars were to fragile it was upgraded from m8 to m10 bolts. Now it is fine…

  • Erik

    If I had a scooter, that would be it. Nice work.

    There is something wrong with the figures. The 60 mm stroke gives a maximum safe RPM of around 10500. BEMP is 181 at 22 HP for 150 cc. Close to the maximum design limit for a properly designed motor. 28 mm carb and no mega phone ? Best guess is around 15-16 hp.

    good effort to build something new, but what about the ones that you sell to your customers ??
    If these bikes break down, it takes for months and months on end to get it shorted out.

    Dimitri you do not feel any personal responsibility on fixing it and will dump all the weight of chasing the supplier to the customer, instead of yourself.

    Apart from that…I should have just choosen something else.
    so should all of you.

    If i knew what i am going through now with this, would have never bought a “super bike” from there it in the first place.

    I just believe enough now, people should now.

    Is it normal for a scooter to take 6 months for a service???

    what do you think?
