LEGO TECHNIC - CIRCUIT SHOCK (SET 8422): IDENTIFICATION
A 1995 LEGO Technic 2-in-1 set featuring 316 pieces. The primary model is a red and black racing motorcycle with a functional V2 piston engine, chain drive, and rear shock absorbers. The secondary 'B' model is a long-wheelbase dragster. This set utilizes the traditional 'stud' building style prevalent in Technic during the mid-1990s, before the transition to studless beams.
Compare with other toys in the archive: LEGO City Ambulance (Set 60330) without Minifigures or Accessories, Greiner-type Papier-Mâché Doll (mid-to-late 19th Century), Dragon Ball Z Chess Set - DeAgostini (2002).
