I still firmly believe and argue that the ZX-RR being bad was because the development of the bike was underfunded and rushed. For one, they ran with an ECU, Chassis, and even Engine (correct me if Im wrong) derived from their superbike program and the former especially was no where near as sophisticated as even the one Suzuki used. Another was that development essentially ran in parallel to the actual racing team with parts and test riders regularly going to fro in between all the way up till their last years. So if we ignored everything else that makes a bike a great package, would running a 180 degree crank Inline 4 with that firing order have the potential to be competitive given the time and resources? Now, correct me if im wrong, but when Kawasaki experimented with that firing offset, it was still a conventional 180 degree crank, right? But with rephased firing timing so the cylinders fired in farther crank offsets at 0-180-0-540 instead of 0-180-0-180?…
