Stefan Everts, 31, turned his dream to lift an eighth motocross world title into reality at Ballykelly in Northern Ireland.
Everts finished his fight for the title with a near perfect day's racing, taking second place in race one and a win in the final moto.
The eighth world championship title for the Belgian is a formidable achievement and further underlines his dominance of the sport and reinforces his position of the most successful grand prix motocross rider ever. Everts 2004 MX1 World title is his fourth straight championship on the YZ fourstroke bikes, after joining Yamaha in 2001.
Race one saw Everts take an early lead, closely followed by team-mate Cédric Melotte, Michaël Pichon and British rider Wayne Smith. Pichon pushed hard in the early stages of the race, climbing into second place by lap two and began to gain on Everts.
The Frenchman made his move one lap later and sneaked past on the inside line, but Everts was not defeated and kept the pressure on repassing his Honda rival in lap six.
The scene was set for a dramatic showdown of the two world champions, but finally lapped riders would decide the outcome. Everts struggled to maintain his rhythm coming through the traffic and Pichon capitalised on this making a pass on lap sixteen and went onto take the race win. Third place went to Josh Coppins, Cédric Melotte was fourth and Steve Ramon took fifth.
After winning his eighth world title after the first race by taking second place in the moto, Everts was determined to make amends and win the second race.
As the gate dropped he hit the first turn in the leading bunch and pushed into the lead as the pack came around on lap one. Everts delivered a perfect score card in moto two and this time Pichon had little answer for the multiple World Champion's speed and consistency.
Everts took a well deserved win, his career total now stands at unrivalled 78 GP wins, with Pichon in second place. Third place went to Estonian rider Tanel Leok, followed by Josh Coppins and Kevin Strijbos in fifth.
Billy Mackenzie was a solid sixth.
"It was the same old story in race one today with the lapped riders," said Everts. "They just don't move over. Luigi Seguy and Billy Mackenzie were in front of me for a few corners and that pretty much blew my victory because Pichon came by me when I got blocked by them. It's a pity because I really tried to win the race.
