Description

Built in the studded era

In 1995 most Technic models still rested on studded bricks with holes through the sides, stacked in layers and tied together with axles and pins. Smooth studless beams were starting to appear but had not yet taken over. Set 8422 belongs to that period. Its 311 pieces spread across 85 different part types, which is quite a wide selection for a model of this size, so the build offers variety rather than long runs of identical steps. There are no minifigures included.

Red and white on grey

The catalogue lists light grey, black, red and white as the dominant colours. Red and white together have a long association with motor racing, which suits a bike carrying a name like Circuit Shock Racer. The light grey is the older shade used until around 2004, so it looks slightly warmer than the bluish grey of modern parts. If you mix eras in your collection, that is the difference you will notice first; the other three colours blend in easily.

The name game

V-twin describes an engine with two cylinders arranged in a V, a layout found on many motorcycles from cruisers to sports bikes. Circuit Shock Racer, the other title, suggests a track machine instead. Both names are attached to the same set, which can cause confusion when searching second-hand listings. Using the set number 8422 is the most reliable way to make sure you have found the right one, whichever name the seller has chosen.

From the loft to the table

Nineties Technic bikes have a loyal following, and many copies now come from lofts and childhood collections. Work through the parts list on this page to see which of the 85 part types you have and which are missing, then track down anything you need. If rebuilding the bike is not your plan, the “What can I build?” tool compares your parts with other sets and suggests alternatives you could build fully or partly from the same pile.
