Honda SL70 K0 Restoration

1971 Honda SL70 K0 - VIN# SL70-1029956

Performed by Randy Marble    www.marblesmotors.com

This bike was built to match my 1969 Mustang Convertible which is Acapulco Blue with White Interior.  The original colors for the Honda SL70 K0 were:   Summer Yellow, Aquarius Blue & Light Ruby Red.  There were just under 80,000 SL70 K0's sold and registered in the U.S.  Many others sold in Canada and other countries, making this the single biggest selling Honda SL.

The steps involved in this restoration process are my interpretation, and I do not represent these bikes to be anything other than what you see in the pictures.  Some parts are reproductions, and some are repaired originals.

Follow Along With The Restoration Process.
