With the RSV4 you get a race ECU that replaces the original, they’re a part you can order about £250 IIRC.
Be interested to know if Ducati sell the race systems in the USA. Was invited to the Speed Triple launch at the Triumph factory the other day. Triumph will no longer supply accessory exhausts that are not road legal due to issues in the USA when Harley were taken to court for doing the same with their Screaming Eagle exhausts.
