Dust, rain, mud, drama - 1989 promised a mouth-watering battle between a stellar line-up of world champions and hard charging challengers.
Reigning 500cc World Champion Eric Geboers, former title-holders Dave Thorpe and Georges Jobe, plus rising stars Kurt Nicoll and Jeff Leisk, were ready for what promised to be a truly unforgettable year of MX action.
While Australian Leisk, in his first full 500cc season, and Dirk Geukens shared the wins at the opening round, old-hands Geboers and Thorpe soon took control to dominate every race at the next three rounds. After four events it was honours even, the pair sharing the championship lead with equal points.
Kees van der Ven was the in-form man during the middle of the season, taking wins in Scandinavia to bring himself onto the tail of the title chase, behind Brit Nicoll and Leisk. However, after seven rounds, it was Geboers who held the lead, almost 30 points ahead of Thorpe.
The British star fought back to claim four wins from the next six races, including double victory at his home round. The slim chances of Geboers retaining his world title disappeared at the penultimate round, as Thorpe took both wins and his third 500cc World Championship.
This is the story of a dramatic season featuring incredible race action, fascinating interviews and all the mud-spitting, high-jumping, bike-smashing moments of an amazing year.
Features action from Holland, France, Italy, Finland, San Remo, Britain, Belgium, Luxembourg and Switzerland.
