Motorcycling Australia has announced a regulations update for Kawasaki Ninja 400 riders contesting the Supersport 300 category in the 2019 Motul Pirelli Australian Superbike Championship (ASBK).

All competitors must now have their ECU reprogrammed by having the rev limiter set prior to taking part in any competition, where it has been determined an increase of the original restricted rev limit of 9650rpm to now 10,300rpm.

After the first three rounds of ASBK, the ASBK management team has reviewed the regulations governing restrictions applied to the Kawasaki Ninja 400 and have approved the new changes.

Competitors can have the revised restricted rev limit installed to their ECU at the next round of ASBK or by following the procedure outlined in Appendix B of the ASBK Supplementary Regulations. This will be at no cost to competitors that have already paid to have the original restricted rev limit set in their ECU.

MA will continue to monitor the performance of all machines within the Supersport 300 class and will alter the regulations from time to time to ensure fair and even competition within the class. This regulation change marks the second update this season. Morgan Park in Queensland will host the next round of ASBK on 5-6 July.
