ASBK Technical Regulations for Aprilia RSV4 1100


Aprilia in ASBK

We revealed yesterday the intention of Matt Walters to race an 1100 cc Aprilia RSV4 in the 2023 2023 mi-bike Australian Superbike Championship.

We also mentioned that Motorcycling Australia would be issuing specific rules in regards to the eligibility of the machine in Australian Superbike, due to its larger capacity than generally permitted.

The first edition of those rules have been promulgated today as Appendix E of the 2023 Sporting Regulations, we include them below.

We believe this move has also prompted others to consider making applications to Motorcycling Australia in regards to other larger capacity models that up until now have not been allowed to race. This ‘could’ open up opportunies for people to race the 1103 cc Ducati Panigale V4, which is half the price of the 1000 cc V4 R that is currently raced by competitors in ASBK.

Interesting times…
