As an established engine builder, Greeves was able to survive while many rivals disappeared, along with the supply of Villiers engines, in the late 1960s. From then on the Thundersley-based company concentrated on its successful off-road competition models. The first (virtually) all-Greeves model was the Challenger scrambler, introduced in 1964. Built in 246cc and (later) 362cc capacities, the Challenger engine incorporated an Alpha crankshaft assembly within Greeves' own crankcases, which were complemented by a new, generously finned alloy top end. Mated to an Albion gearbox, this new power unit was carried in typically-Greeves cycle parts consisting of a cast alloy beam frame and leading-link forks, the latter of the 'banana' type from late 1965 with Cerianis optional. By that time the Challenger was being built in improved MX2 form, with duplex primary chain and stronger, kidney-shaped gearbox, while a 362cc version had been added to the range. After two seasons of testing in competition, the production Challenger appeared for the 1967 season mounted in a lengthened frame (for improved stability) while also featuring new conical alloy hubs.

The 24MX2 Challenger offered here appears to have been restored to a high standard. There are no documents with this Lot.
