Additional photos of this 1967 Matchless G85CS are available here for your perusal.

The successor of the G80CS and the predecessor of the Norton P11, the G85CS was one of the last bikes to be released with the Matchless name. It was a 4-stroke scrambler built to compete with light 2-strokes that were having success in European scrambler racing at the time – Matchless brought out an all new frame, ultra light hubs, an alloy fuel tank, and more.

The frame on this example heavily drew from design aspects of the famous Rickman Brothers, utilizing a duplex tube frame of Reynolds 531 tubing (all welded and lug-less) connected to a lightweight fork. A machined front hub and magnesium rear hub were used in an effort to keep weight down, along with other various lightweight fiberglass and aluminum components. In total the stripped down competition machine (G85CS) reportedly weighed in at just 318lbs, 42lbs lighter than the G80 model it replaced.

At the heart of the G85CS was a tuned version of the proven 500cc powerplant that had powered Matchless’s G80 model. The G85CS boasted increased compression (12:1) with an improved bottom end compared to the regular G80 engine, and a 1-3/8 inch Amal GP carb was standard on all the CS models. A Norton gear-driven oil pump was used in place of the old reciprocating design that supposedly dated back to the 1920s. As a result of the collective changes, the CS’s power went up to a reported 41hp at 6,500 rpm.

The seller of this example adds that “in the first era of televised coverage of motocross racing in Europe, the big Matchless played the heavy, and they were raced by Vic Eastwood, Dave Nicoll and Chris Horsfield for only two years before the Matchless brand was put to bed. Every G85CS is a factory-built race bike from AMC’s competition shop.”

This example is VIN: C/11301, Engine #: G85CS/290. The seller has owned it for over twenty years.

There is no odometer – true mileage is unknown.

The seller states that there are “no upgrades, this bike is all period correct.”

Cosmetic Blemishes:
The seller notes a “small dent on exhaust pipe.”

He adds that there are no known mechanical issues. “The bike has been started but not ridden in over 20 years.
