Now I see why my bike was vibrating while braking




Something Strange on this picture



Nice to see other derbi gpr than mine




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
Now let's start everything from the beginning
Cleaning of the frame

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.

So the engine was dirty. I wish to paint it because the original paint is going out.











Cleaning of the starter

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.





The frame






New swinging arm and headlight support



The battery cover



Clutch tool



New windshield




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

Hello everyone, things are getting cool
New frame, new swinging arm, new shock absorber and a lot of new parts
I've cleaned the wiring assembly, the tank and so much others parts
I want this gpr to be clean

[benito brz]

Some fresh paint




electricity
















Chain tensioners




Tail light

Electric case








New parts from Germany












I've noticed there is 2 different types of coolant/oil tank, the new and the old one.

A lot of new parts

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,...)








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