The Matchless Model X was developed for V-twin enthusiasts and had a specially reinforced rear frame for heavy-duty sidecar work. At the end of 1936 the Model X was upgraded and rebranded the Sports Tourist, with a shorter wheelbase frame which improved roadholding and steering. The Motor Cycle road tested the Model X in May 1937 and noted that the steering was light but even when cruising at over it did "not become so light as to necessitate-use of the damper." Performance of the engine was described as "delightful" and although not a sportster it was capable of and could reach from a standing start in a quarter of a mile.
