Hello
Can someone clarify what is the correct width for x34-0, 150cc bike rims? I just acquired two wheels for my B33-2 project, but they came with quite narrow rims. Just started to wonder if they are originally from 150cc machine. Correct size for B33-2, by the 1933 parts list, is 19 x 2+1/4. Are X models using this same size?

Ps. If I have understood correctly, back in a day rim size was given as the external width, while later it is given as the internal width. Right?
The same wheel .. 19 x 2 1/4 for 25 x 3 in tyres are listed for X34-0 / B34-1 and B34-2 in parts book (in library in members area on website) .... hope that helps

Ok. Thank you very much.
I also suddenly realized that my new wheels are 20 inch. I'm quite sure that the same thing goes with those.
