The world championship kicks off in Holland with wins for Ken De Dycker and Tyla Rattray.

Big Ken De Dycker came out swinging in the super-rough conditions at Valkenswaard. In his first MX1 GP as Suzuki team-mate to reigning world champion Steve Ramon, de Dycker was peerless, taking the lead early in both races and winning at a canter.

Ramon himself put a third and a fourth together for second overall in the book and was happy with the 38 points after falling sick on Monday which stopped him from training all week. German Max Nagl was on step three of the podium, tied on points with Ramon.

In the MX2 Tyla Rattray came out like his old self, winning both motos in the rough Dutch sand. Last years heatwinner in uddevalla's GP Tommy Searle came out like the pretender to the throne, charging hard early in moto one to briefly take the lead before a crash dropped him back down the pack but the KTM star recovered well to take third.

Antonio Cairoli came out under par, trailing Tyla home in both races and unable to mount a challenge to the South African.
