Cafe Racer Ninja 250 build aka the polished turd

The backstory on this bike is that I picked it up about 8 years ago so I could teach my friends to ride. I bought it for $200, it was cosmetically beat up and wouldn't start. I took it home and charged the battery and it fired up. That was great luck considering at that time I knew very little about bikes and just started riding two years before.

I bought it for my best friend who was interested at the time but still to this day doesn't have his license but still talks about getting it. I taught about 5 people to ride. I rode it occasionally but it was beat up from being dropped so much.

I decided to do some fiberglass work and paint it. Unfortunately this was the first thing I ever painted. I used black primer and neon blue base, this caused the blue to become barney purple. So still ugly and the bike sat for years.

I got married and my wife is slightly interested in riding and liked the look of cafe racers. If she decided not to ride I would have a fun around town bike, win win. I love idea of a cafe racer, I was living with my parents and had a 1969 CB350. I tried to rebuild it but didn't have skills, disaster of a garage, and proper tools. I sold it out of frustration about 6 years ago. I regretted selling it and never finishing it.

I bought a house with a 2 door garage with a loft above the garage. It was the first thing I started working on. It had bare concrete floors and no drywall. Now I have the space and slowly all the tools I needed. This build took about 3 months.

All that is left to do it finely tune the jetting on the carbs but the roads are covered in snow right now. I just bought a powder coating gun and media blasting cabinet and will do most of the parts this winter. Picking up the oven tomorrow. I will do just about everything metal part on the bike myself except the frame since I won't have a big enough oven. My epoxy rattle can paint job is fine for now as a temp paintjob.

Here is the link for entire build, the details and the shop. I am slowly loading them off photobucket.

Stripped




Primed with self etching primer. Once again this is a temporary paintjob and wanted to make sure everything fit together before I do a powder coating.


High Temp engine paint with a clear.


Epoxy Paint

Valve Cover


Forks- Epoxy painted and Cleared


Radiator and fan painted. Carbs installed





Rusty exhaust. I removed the rust and painted with a 1200 degree paint. Then wrapped it in titanium exhaust wrap.



Painted the front and rear wheel. I rebuilt both calipers and painted them with caliper paint.



Centerstand painted and new spring


I decided to cut off all the tabs that hand off the rear of the bike. I then took about 6 inches off the rear subframe.


I welded the rear subframe back together and slightly change the angle.

Now I wanted to round the rear out. The tube pictures was my first one and did a new one with a thicker more suited tube. I don't have a pipe bender so I made small cuts and slowly bent into the correct shape. Then welded and polished it out.




I didn't like the gaps in this picture so I later went with a larger tube which you will see later.

Since cafe racers don't have airboxes I removed that. I then fabricated a new battery box. I made it hold the ecu, rectifier and rear brake reservoir. It has a horrible paintjob but I will redo it in a couple weeks once I get the powder coating going. Don't judge lol.




Then I welded something for the new seat paint to sit on, the gaps were filled in later. I also made a frame for the seat cowl. I used a square tube and sliced and bent like the previous pipe.





The seat pan gets chopped and altered. The Rear cowl mounts get fitted. Then the cowl is built.












The bike gets a round single headlight and aluminum fork ears with turn signals. Also barend mirrors.




Almost done. Now I need to get the seat upholstered in Naugahyde.



Back from the upholster and it is not 100% since there was a language barrier but I will do some tweaks later. Thats it. The bike is done.










Here are some pictures of my shop and my other bike.

Welding area: Lincoln Mig welder. 2 grinders. Bench grinder. Scrap metal. Oxy/Ace torches




My gear and winch operated loft stairs.


Pegboard Lots of pegboard. I hate a dirty unorganized garage. My parents garage was unorganized and promised I wouldn't work like that.



My couch for staring at my bikes or thinking of fun projects. My new sand blasting cabinets. I have air lines throughout my garage.


Helmets and more gear. Wall mounted shopvac which is great! I even have a roomba in my garage. Just about the only garage that you can walk barefooted in. Magnets on the roomba to pick up the metal bits.


Hope you enjoyed. It was a fun project. I think I managed to shine a turd.

pure awesome
Shine? That turd is positively glowing!

Well done. Not a fan of the brown seat myself, but who cares? You've rolled up your sleeves and made something out of nothing - you can be very proud.

If only more riders would get stuck in like you have rather than just bolting on a few pieces of anodised tat and avoiding anything more involved lest they get their hands dirty or break a fingernail.

Thanks! I am so happy how it came out but I know it will still be working on it for another year, fine tuning.

Yeah the brown doesn't work great right now. I purchased some dark green powder coat to paint the valve covers, radiator hoses and random parts. That should make the brown work. I will have that done after xmas.
That is awesome, well done! I want your garage!

Slow is smooth, smooth is fast.
Clip-ons? Eventually?

O.B
I would have to do some serious tank modifications, installing lower clipons will cause the bars to hit the tank. So much so I would have parking lot maneuvering problems. There just isn't enough room. I will eventually modify the tank with cutouts but that will be next winter.

Thanks firedue. I don't even want to know how time and cash I dumped into it. I am constantly organizing it and moving stuff around to fit more tools and not have it sloppy looking. I am almost out of wall space.
The loft really help to keep the clutter down. Here are some pictures of the loft. I carpeted it using carpet tiles. I sell flooring so I get full sized carpet tile samples for free. Obviously these were accumulated over time. They are also great to use in the shop. I use them under a bike while working on them or changing oil, or just dirty jobs. I installed them so when I have to crawl around up there I am not on dirty plywood. When the stairs are down the loft door opens automatically. When the stairs goes up the door seals the loft so I don't lose heat or AC. Its all operated by a winch I installed.

That's just a classy looking bike you made. I am very impressed considering what you started with. Well done.

Oh yeah, I hate you because of your shop and it's cleanliness. I can never keep mine that straight.
Nice job!
I have work bench envy...pegboard is the word.

I love my pegboard. I really don't understand having a tool storage cabinet then again its rare my tools ever leave my shop. Spending $300-$3000 on a cabinet and having to constantly open and close drawers. I like having everything out in the open and I know where it is and is easy to put away. Almost everything has a label behind it.

I think there is 24'x4' worth of pegboard in my shop.
Dude that looks amazing! Just picked up a free bandit s 600, and will be going a similar route. Thank you for the inspiration:thumbsup:
Seen a lot of these older Ninjas brought back to life as cafe racers. I think they make a fantastic platform to start with. Looking good! :thumbup:
Powder coated more parts. I did all the accent colors today. Also not easily seen is the metal coolant hoses.

Also powdered the rearsets, rear brake lever and exhaust hangers in gloss black.
