1973 Hot Wheels Rumblers Rip Code
Casting #: 66571 listed variation
1. TOOLING
The Rip Code was first released in 1971 as part of the inaugural RRRumblers line. It is a heavy-duty three-wheeled "trike" design featuring an exposed, oversized V-twin engine and a roll-bar frame that extends over the engine block. Unlike traditional two-wheeled motorcycles, the trike configuration provided the necessary stability for performance on standard Hot Wheels orange tracks. The "Roar" factor was a marketing hallmark of the line, produced by the vibration and resonance of the hard plastic wheels against the track surfaces during high-speed descent.
- Designer: Howard Rees / Paul Tam (Attributed).
- Scale: Approximately 1:64.
- Body Material: Die-cast ZAMAK.
- Functional Parts: Rotating front fork and rolling wheels.
The Rip Code was packaged with a removable plastic rider figure designed to "sit" on the vehicle via a small peg-and-hole system located on the seat. The rider associated with this casting is commonly referred to as the "Mean Machine" or "Road Hog" style figure, characterized by a leather-style vest and a helmet with goggles.

- Front Wheel: Small, narrow plastic wheel mounted on a metal fork.
- Rear Wheels: Two medium-width plastic wheels designed for track balance.
- Base-Plate Markings: "Rip Code", "Hot Wheels", "RRRumblers", "© 1970 Mattel Inc", "Hong Kong".
- Axles: Thicker gauge than standard Redline cars to support the weight of the trike design.
Due to the play-centric nature of RRRumblers, finding high-grade specimens is difficult. Specific "Condition Killers" include:
- Handlebars: The most common point of failure; the thin plastic is prone to snapping off the fork.
- Rider Peg: The small plastic peg on the rider's underside frequently breaks off inside the bike's seat hole.
- Tail Pipes: The chrome-plated plastic exhaust pipes often suffer from "chrome loss" or snap off entirely.
- Kickstands: Though Rip Code is a trike, the integrated molding can suffer from "flea bites" or zinc pest in poor storage conditions.
Values for RRRumblers have seen a steady increase among "Redline Era" collectors, with the rider figure accounting for a significant portion of the total value.
