Dutch rider Barry Veneman on the Hoegee Suzuki has posted the fastest time in first free practice around the modified Assen circuit, ahead of round nine of the World Supersport championship.

The track had been reduced in length by a kilometre and a half making all previous lap records redundant. Veneman lapped in 1min 43.304secs with Robbin Harms on the Stiggy Motorsport Honda just 0.282secs off his time.

Third fastest was reigning World Champ Sebastien Charpentier on the Winston Ten Kate Honda with fellow French man Yoann Tiberio on the Mega bike Honda running in fourth. Tiberio's team-mate Katsuaki Fujiwara is making his return from a wrist injury and was running in seventeenth at the end of the first session.

The Australian pairing of Kevin Curtain and Broc Parkes were in fifth and sixth places respectively. The Curtain on the Yamaha Germany machine will be out to beat Charpentier this weekend as they are currently neck-and-neck on championship points, with a joint lead.

The only rider in the session to crash out was David Checa who lost his GMT 94 Yamaha with twenty minutes of the session to go.

The British contingent of Stuart Easton and Tom Tunstall were running in twenty ninth and thirty third.
