Following a meeting and vote of the AMA Rules Committee in Ohio last Thursday, and subsequent ratification by the AMA Board of Directors, AMA Pro Racing has issued a Competition Bulletin making Traction Control legal, effective immediately. Any type of traction control is now legal in the Superbike and FX classes, including the type that requires use of a front-wheel speed sensor--an example being the system used by Ducati in World Superbike. Traction control that doesn't use non-stock sensors--an example being the BPD system used by Jordan Motorsports Suzuki at Barber--is now legal in Superstock and Supersport. Traction control systems that use standard sensors only are available for about $8500 per motorcycle. The text of the Competition Bulletin follows: All Road Race Licensed Riders and Season Credential Holders FROM: Kevin Crowther, Director of Technical Development DATE: July 17, 2006 SUBJECT: Effective immediately replace rule E.23.A pg 36 with: a. For Superstock and Supersport, any form of engine control system that can actively change the performance/acceleration of the engine using input from any sensors that are not OEM on the motorcycle, to create a situation of better traction at the rear wheel at any time while the motorcycle is being ridden is prohibited. Should you have any questions concerning this information, please contact Kevin Crowther at (614)856-1900 ext1230 or firstname.lastname@example.org.
