KTM Australia this week launched its 2013 model SX-F motocross range at the Louee Enduro and Motocross Complex in New South Wales.

MotoOnline.com.au attended the launch, which included the highly anticipated 450 SX-F, developed with direct input from American Motocross Championship leader Ryan Dungey.

Also on hand during the launch was both the 250 SX-F and world champion 350 SX-F, which have both benefited from up to five extra horsepower and an assortment of chassis refinements similar to the 450.

KTM Australia general manager Jeff Leisk was at the launch keeping a close eye as the national press put the bikes through their paces, as were members of the JDR/KTM Factory Racing outfit.

Former national MX2 champion Ryan Marmont rode with the media throughout the launch, on both his current race bike and the 2013 range, giving all three models his stamp of approval.

Across the board the improvements are clear, with the Austrian manufacturer continuing to up the ante at an impressive rate as its commitment to excel shines.

Stay tuned to MotoOnline.com.au over the coming days for images, video and the full review on the 2013 KTM 250 SX-F, 350 SX-F and 450 SX-F.
