    As per the title I would like to know what model my ST70 is?

    Frame number: ST70-511852
    Engine number: ST70E-100875

    Also how do I find out what the original colour was other than sanding down?

    1969 ST70, either type l, or an early type ll. Type l had the longer, duckbill/German helmet fenders & low-mount exhaust.

    Honda did not specify color via VIN, i.e. there are no "color codes" of any kind. Only way to know the original, factory-applied, color is to find a remnant of it...somewhere on the frame. Best places to look: rear shock mounts (upper or lower), inside the tank area (have to remove the tank first), above the engine (have to pull the engine), steering stem (have to remove the upper fork from the frame), brake pedal pivot (have to remove the brake pedal). There are other possibilities but, they are far less likely to have eluded paint removal. And, all of this depends upon the thoroughness of the painter. When I refinish a frameset, everything is stripped & bead-blasted back to clean "white metal".

    FYI, Candy Sapphire Blue was an OEM color, in this era. Thus, yours could have been this color when it was delivered to its first owner, 48 years ago.

    Thank you for the detailed reply @racerx

    I want to replace many of the items that aren't up to scratch with OEM parts.

    Would you say using the Official Honda Shop Manual is sufficient to restore the bike?

    No, but, it's still a valuable resource. The shop manual is good for engine & carb specs, as well as front end servicing. The factory parts manual would tell you more about assembly and provide part numbers... for everything, including the engine & carb.

    For parts that are available new only as reproductions, neither manual will be of much use. And, when it comes to things like seat restoration, plating/metalfinishing/polishing, teardown & assembly among other details, you're pretty well on your own...unless you have a helpful resource like a web board, of informed members that can help answer your questions.;)
