Matchless G12-CSR Restored Condition 1965

The Matchless G12CSR, also known as the "Competition/Sprung/Roadster," was nicknamed the "Coffee Shop Racer" by its rivals. Equipped with a distinctive two-inéén "siamese" exhaust system and improved camshafts, the CSR offered high performance for its time. With a compression ratio of 8.5:1, higher than other G12 models, it distinguished itself, making it a formidable competitor on the road and track.

Head engineer Jack Williams, transferred from the development of the AJS 7R, tackled problems with leaks and vibration, and refined the motorcycles for racing. These efforts led to notable victories, such as those of Ron Langston and Don Chapman in the 1963 Thruxton 500 endurance race on the AJS Model 31, a counterpart to the G12. Following this success, the G12CSR was nicknamed the "Monarch" and given dual carburetors, which further distinguished it from its predecessors.

By 1964, the Matchless G12 CSR had a Norton frame (slim frame) and a Norton telescopic fork, which improved performance and handling. This particular Matchless was originally sold in the U.S. for desert racing. Although there are records suggesting that only 22 of this type were produced with this engine, this claim has not been verified.

After sustaining damage to the front fork in one of its early desert races, the motorcycle was stored in a barn until the early 1990s when it was rediscovered and sold to Sweden. After its arrival in Sweden in 1992, it was restored to its original condition and was finally approved for use in 2001. Until its acquisition in 2016, it had only ééone owner in Sweden.

With only 580 km on the odometer and an almost new look, apart from the slightly worn saddle, this Matchless G12CSR, with a competitive lightweight aluminum tank, is a truly special motorcycle that deserves a place in many collections.
