The Yamaha Motor Finance Australian Superbike Championship presented by Motul Pirelli (ASBK) is thrilled to see Yamaha Motor Australia maintain its commitment to the championship with the highly competitive and exciting YMF R3 Cup. Yamaha Motor Finance (YMF) will once again support the feeder class, which will adopt the same technical rules as the highly popular Australian Supersport 300 class.

The technical change is aimed at simplifying the process of YMF R3 Cup competitors cross entering into Australian Supersport 300 events, providing YZF-R3 competitors with a distinct advantage of extra track time and the option to take out the number one plate in two classes, with one bike.

Yamaha Motor Australia’s Group General Manager Financial Services, Brad Ryan is excited to extend Yamaha Motor Finance’s support of the YMF R3 cup; “On behalf of Yamaha Motor Finance and Yamaha, we are eagerly anticipating the 2018 YMF R3 Cup season and the ensured success of ASBK at all levels of competition,” according to Ryan. “This year showcased entertaining, thrilling and cost effective racing for its competitors.

“The YMF R3 Cup is aimed at entry-level road racers with an emphasis on the enjoyment of riding and competing on equal machinery. Building a solid future for Australian road racing for a cost effective price. Competitors can head to their local Yamaha dealer and attain the race ready version of the YZF-R3 with YMF,” Ryan concluded.
