I was considerably challenged
by this project and I looked up
hundreds of photos and got
inspiration from the well-known
online motorcycle blogs.
“I built the entire motorcycle
while studying medicine. No, I
certainly have not been inspired
by the hospital! I have been a
racing fan from a young age—
Formula 1 and Le Mans—hence
the Gulf Racing colors. I first
started the project in my parents’
shed. After the bike had been
in bits in there for three and a
half years, I went looking for
a workplace in my area. That
was the ‘Kickstart Garage’ in
Amsterdam, which was a real
hit. They are really fantastic
guys who work with motorbikes,
“ELECTRICS WERE QUITE
A CHALLENGE. BUT, HEY,
IT’S LESS COMPLEX THAN
OPEN HEART SURGERY!”

PAINT AND FINISH:
Gulf Racing colours. Sprayer: Niels Paintcould assist me with advice and
suggestions, and occasionally lend
out some tools. As a result, the
project gained speed.
“As I was just starting out, I
also had to buy myself a lot of
tools because I wanted to do
most of the work myself. Good
for someone in a white coat, eh!
But I outsourced the metal and
spraying work because you don’t
learn that in the hospital, anyway.
I had the swinging arm fabricated
by Gerard Kramer (known in the
Dutch bike scene as Jerryt). He is a
professional welder and I wanted
it to be good and safe so that I
wouldn’t end up the emergency
department on the other side
from my colleagues! I wanted a
swinging arm that would be the
same length as the original, but a
lot wider and a fatter rear wheel
had to be added without too much
offset. The Mojave tank was also
been modified by Jerryt. It is
slightly extended, so that it fits
nicely on the seat. He also madehttp://www.100-biker.co.uk | issue 250 | 100% Biker | 41
