Built February 1977 (6180710).
These bikes were designed originally to have snowflake mag wheels, a production fault/delay caused the first year to be sold with spoke wheels, having regard to BMW's practice of using what parts are to hand (some of the last R90S's to come to Australia had 1,000 cc barrels and /7 wiring looms) it is possible that the earlier production of the 77 model had a different wheel finish to bikes built later that year.
