Honda CB50 final result

Post  Haakie on Mon 31 May - 16:11

Hi guys,

This winter I converted a standard Cb50 into a caferacer. It started with some minor plans but eventually I completely took the moped apart to build something special. The tank is one of the first things I bought, it's a rare CB50K1 tank in candy gold. Some other things I bought were clip-ons, a polyester seat from Harrie Kruijs and a 18 mm Keihin caburator. The rest on the bike is made by myself. Also I sprayed the seat myself in candy gold, this was very hard but I was a good learning experience! Here I will place some pictures of what I've done this winter, hope you will like it.

Started with a good CB50, with a fine running engine and not ruined over the years. Only thing which was bad: A 2 stroke Mikuni carb.


A lot of parts in the mid triangle. I want to have everyting out of there to create a clean look.


Cleaning the engine


Frame is straight and not rotten, but the rust is starting on the underside so I remove all the paint.

This is a very nice base for a caferacer.
I always liked the little Honda's.

good luck

Thanks!


This is the front fork how it came off the bike. The inner forks are still in perfect shape so I can shorten the front fork!



This is a little bit better but still not good enough!



And the NOS tank! Still had to find some Hondo logo's which would fit



Old vs. New

Great job so far on the CB Haakie man, new tank looks much more like it. Succes with the next steps.

Talking about beer ; No Beer like a Belgium Beer , although there is one Dutch beer (prolly more) that counts in for one of the best in the BENELUX , it slips my mind, prolly cause im drinking Optimo Bruno Twisted Evil

Thanks guys for the positive reply's. By the way I prefer Corsendonk tripel!

After hours and hours of cleaning, sanding and polishing this is the engine!
The engine was perfect before the restoration so I decided to not take it apart. I will mount an original but pretty big Keihin 18 mm and an speed funnel (kelk).





While I was restorating all the small parts I made an impression of the bike. The headlight is from a old type Dax with build in speedo to keep the profile as low as possible. The headlamp mounts/ears (27mm) are from Takegawa.

I'm using this 'kroonplaat' at the top of the front-end to lower the two forks 3 cm. This way the bike get a little bit lower, but the fork will get longer so the front end will be shortened later in the project.

Honda C320/ SS50k0 kroonplaat and Cb50 T-Piece




Removing paint from the frame



Cleaned the front caliper (mechanical version!) and some fresh paint



Some parts together

Thanks guys!

Air funnel!



Shortened the steering angle with these little pieces of metal, so the clip ons will not touch the tank.



Polishing the controls



Cutting the front fender for a cafe racer look. Cheap and simple.

To keep things clear; I already finished the project 2 weeks ago. So these are all old pictures from this winter.

New springs, Jap style



Making the seat stronger by gluing in a wooden base plate to mount on the frame.



Sprayed the front fender



Foam for the seat




With this special tank, I cannot mount the bobine under the tank, so I made it under the seat (Honda SS bobine)

The seat didn't exactly fit near the tank. So I made an extra piece of massive PVC and bolted this on the seat:







Sprayed it black to see how it looks. This will not be the final color.



I decided I wanted the seat candy yellow just as the tank. I also wanted 2 little black lines over the seat, just as the Honda SS50 sports moped had.



The candy color I picked out of the color book at the paint shop was Yamaha candy yellow. It was almost identical to the tank. The base color is white, and after this you have the spray a few layers of yellow. These layers have to be the same all of the seat, otherwise you will see dark spots!





Very succesful I guess, only with a few spraycans!


Placed the ignition lock from a Honda SS50 under the seat, in the frame.

The seat looks very nice.
I know how hard it is to get a good result whith a spraycan.

The front suspension has been shortened. Almost 5 cm.

I had to remove the underlegs



After this, the inner legs were shortened by Ronald who races a CB50 himself (50 cc with a top speed of 120 km/hour).


I made a bracket to hold the taillight and battery in place. The battery will go under the seat so you won't see anything of the electrics.




And also the final big thing, electrics. I designed my own electric diagram.
