Allan loved Australia and returned later in the year after finishing third in the British team at the Motocross des Nations in Czechoslovakia on September 1975, behind Belgium and the winning home team.

Allan was part of the 1975 international promotional tour, accompanying new World 125cc Champion Gaston Rahier, with the Belgium rider winning Suzuki’s first world championship.

With the sales boom of the early seventies beginning to significantly affect motocross, Rahier and a host of international riders toured Australia in 1975 to promote the new Japanese lightweight motocross machines.

In addition to the two Belgium riders Rahier and Camal, the international riders included Japanese development rider Masanori Ozeki, all on works Suzukis, Bultaco rider Allan and Gualtiero Brissoni (Italy) on a SWM 125, Per Klitland (Denmark, Yamaha) and Ivan Miller (NZ, Yamaha).

It was a whirl-wind tour with the riders competing at a second Wallan International on Saturday, 15 November, then flying out to Tasmania to compete in the Australian Motocross Championships the following day in Tasmania on Sunday, 16 November 1975.

Rahier won all classes he contested (125, 250 and Unlimited) at the South Arm Road circuit in Tasmania, and Allan finished second to Rahier in the Unlimited class.

At the Sydney International at Amaroo Park, Rahier and Allan came together and both fell off, which caused a heated exchange.

Allan was quick and was the only rider to stop World Champion Gaston Rahier from making a clean sweep on his Australian / New Zealand tour in 1975.  At the Suzuki International at Tivoli on 30 Nov 1975, Allan won the first two legs on a Bultaco ahead of Rahier, who comfortably won the third race after having his gearing altered.
