Built from scratch: 250R

[sticker_sääp]

Hello Guys,

after a few requests Loizl forced me to reactivate my old 3WW account, to show you my 250R project, wich was built in parallel to his Tecate 125.

I always wanted a badass two stroke trike like the ATC250R, but they are hard to find and to expensive over here in europe. So i desided to built my own.

The design of the trike began during the abroad year in england of my engineering studies. I bought a cheap Honda CR250 engine on ebay uk in great conditon as you can see.

Is your intent to buy it piece by piece then? I seen a post where someone did just that and it was somewhere around 2/3rds more money than buying one and starting from there. I applaud your efforts and can understand your issues sourcing parts in Europe. Good luck!

The project is already finished and the total costs were far below 1000€.

I will now post part by part the complete manifacturing... It just takes some time to upload all the pics and write a few words to every step.

After a bus ride across europe the engine arrived save in my workshop:

The engine case was cracked by the pre owner, so it was necessary to TIG weld the cracks and after the paintjob it looked like that:

The clutch cover and the generator cover was to damaged to weld it and therefore new covers were cnc milled:

A jig was weld around a tecate frame to get the position of all the holes and tubes:




Here is the finished frame compared to a tecate 3 frame:

First testfit of the engine into the frame:

I had a CR250 fork laying around from another project which was combined with a 250R tripple clamp from ebay.
The tank is from a Honda MTX 125 that i cannibalized a few years before:


Here are some pics of the original magnesium clutchcover that was burned

Some picture of the plasma cutted engine mounts and of the engine fitting in which was a PITA:


Design of the aluminum subframe...

Safety first, therefore i bought nerfbars for a yamaha blaster that fitted on my frame with some minor cutting and welding action...


A red fender of a chinese quad won on ebay and the 4 snows of my former built the "Mocate 250" completed the first mock up:





Later this week i will go on with my report but for the moment this should be enough... see you

Wow! Nice work!
When you said from scratch you weren't kidding.

What is the paint on the power valve covers? It's a interesting color/look.

Nice trike, Thank You

The powervalve covers were anodized and were expected to be red but honda used a lot of different alloys for different parts so they came out some kind of Bordeaux color.

Thank You, with casted aluminum it's tough to anodize any color other than clear or black.

I like them they look like a exotic works coating.
