Anyone recognise this logography - Chinese? Japanese? Mandarin? Korean?

This was stuck to the too tube of my late 80s tushingham. Would love to know what it says!

It’s in Japanese. It’s upside down. It says something along the lines of “high performance/efficiency bicycle (two wheeler)”.
Best regards
