When electronic rider aids began to appear, first on European bikes and then on Japanese product, old-timers croaked out objections. Manufacturers were trying to turn courageous riders into gutless capons! Rip out the electronics and man up! But just as in dirt track and roadracing four decades ago, people were seeking to control traction to go faster by whatever means were available. AFT has a 40-pound maximum weight limit for rear wheels precisely because, otherwise, builders will inflate tires with water instead of air or otherwise add wheel mass to act as flywheel to suppress wheelspin. The act of suppressing wheelspin, however you implement it, is traction control.
