Pay attention! These frames are super strong! We do not make them from normal steel but from Chromoly steel.

Material: Chromoly steel
Length: approx. 46 cm (sitting part)

This frame is different from most subframes that you see at a BMW R80 Cafe Racer or Brat. Not that "triangle", but a floating frame with the necessary supports. 

For example, many of our seats fit exactly (yes, this has been taken into account in designing).
There is also a bracket, where you can attach things like a tail light and/or mudguard.

Think of seats: 69-0015/69-0016/69-0017/69-0018/69-0019/69-0020/69-0021/69-0022/69-0023/69-0023/69-0024/69-0025/69-0026/69-0036/69-0042/69-0043/69-0044/69-0049/69-0056/69-0065/69-0067/69-0077/69-0088/69-0095/69-0097

We have all passed on the materials and everything is cut to size. In short, never a deviation in a subframe in design, or safety.

Note: Beware of the Chinese copies. Our frames, the original ones, are made in The Netherlands and are calculated and made of Chromoly steel. We see that we are being copied, but do not save on safety.
