Image

Something Strange on this picture :idea:

Image

Nice to see other derbi gpr than mine

Image

So now we are in the present, I've completely disassembled the bike to make every parts perfect, make a perfect restauration because there were a lot of defaults.
I made a timelapse of the disassembly on my instagram: benito brz

Hi guys
Today I want to show you the state of the frame, i'm planning to fix it before painting it. I met a welder which could help me to fix it, he works in a workshop and he can fix everything by welding.
His website: http://preparation-moteur-yma.fr/
This guy is an old pilot, he has the speed record on the track of Le Mans with a 750 Kawasaki H2.

Hello everyone, my frame was too expensive to fix so I bought another new and totally blank frame, and some others parts.
I bought it at a shop at Kerpen in Germany, I was impressed to see how many brand new parts of derbi ,aprilia, cagiva… the guy was selling.

Image

The frame

Image
Image
Image
Image

New swinging arm and headlight support

Image

The battery cover

Image

Clutch tool

Image

New windshield

Image
Image

The next step is to punch the letters and numbers on the frame.

I will do an epoxy paint on my wheels, I will not do it myself so I had to remove everything on the wheels (tyres, brakes discs,...)

Image
Image
Image
Image
Image
Image

So I will paint the wheels in white because i want my bike to looks like a Lucky strike bike
It could be awesome :starry: :starry:
But I'm waiting to the paint workshop to open because of the quarantine.
