Common topics about HOREX und motorbikes

Here you will find a description of technical terms where i "stumble across" during the work on my HOREX Regina.

Technical terms on pistons.

After i disassembled my engine i must determine, that the piston is probably not the original one.

Now i want to measure the dimensions of the piston, to compare it with the original. To do this i have made this picture with the technical terms on pistons.
