A Go-Cart
The lost year for Technic. After the release of the pneumatic sets in 1984, many of which were not released in some markets until 1985, and anticipating the Arctic Action series of next year, Lego produced only 1 new set for 1985, the promotional 1972 go-Cart. which was designed as a starter or trial set.

The small blue Go-Cart had only 1 function, front-wheel rack and pinion steering. To its credit, however, it used 8 small wheels to simulate wide tires.
In 1985 LEGO only released one Technic set, presumably because the public was still digesting the new pneumatic system from the previous year. Set 1972 was a Go Cart which was released only the USA as a promotional set and is therefore somewhat difficult to find.
Besides this one set one technic part was released: Gear Worm Screw. This part however did not appear in any technic set until 1986 in 8660: Arctic Rescue Unit.
