A real Motom racer had a special tank, it was longer than the Sport tank used on the production road bikes.
To make something special I tried to find a tank that had the similar shape, a Mival tank has some similar roundings so started from there.

The tank is too small at the front so had to open here up

You see something off the drup shape in it.

Well, first cuts are made.

I could now place it to see how she looks

Not bad but it misses the special cut out the real Moton tanks has.

So start cutting the top

Start making the replacement top

Dubbel welded

Don't have the real dimension so I just kept it 90mm by 200mm

Welded the side's
Keep in mind it has to look hand made so not that precise

Cut the roundings out

Well, it needs to be placed somewhere here

First impression from the back
![](images/20200424_153144.jpg)
At the front, it's not too wide, but certainly not too small

From the Left

From the Right

Certainly worth working this tank out, and see how the end result will be
