Race Rules and Procedures Section 2.8, Motorcycle Usage, states that American SuperBike is now the only class allowed two complete motorcycles, “providing that all such motorcycles have been approved by Tech Inspection in the rider’s name.”
Daytona SportBike, SuperSport and Harley-Davidson are limited to one complete motorcycle, but may have a pre-assembled frame if a rebuild is necessary during a race weekend. The pre-assembled spare frame may include the main frame, bearings, swing arm assembly, rear suspension linkage and shock absorber, upper and lower triple clamps and wiring harness. Only after a team has decided to rebuild a crashed bike, and after receiving approval from Tech Inspection, can they bring the pre-assembled frame into the work area. The rebuilt bike can only be used after the session in which the damage occurred has ended. If further damage is incurred after the spare frame is used, “the assembly work must be done using a bare frame with no components attached.”
Qualifying regulations have been changed slightly, with Section 2.18 stating that in American Superbike “a rider’s best lap time must be within 108% of the fastest qualifying rider’s best lap time,” as opposed to the 107% limit on the books in 2013. Daytona SportBike has been changed to 110%, from 109% while SuperSport and Harley-Davidson remain unchanged at 110%. Additional qualifying opportunities may be available at “Single Header” events, with rules now stating that “in the case of ‘Single Header’ events, at the discretion of AMA Pro Racing, the final on-track session (warm-up) prior to the respective race may be considered a qualifying opportunity.”
Gridding procedures now indicate, specifically, that “there will be three machines per row.” Jumping the start will result in a 10 second penalty if the race is uninterrupted, and a rider’s position will adjust accordingly after the race end. If riders are forced to re-start, the offending rider will be placed on the grid according to the penalty incurred. “When the race restarts and the field completes one lap, the original jump start time shall be deemed as having been served in full and the rider will be scored by their physical position through the balance of the race.”
The primary change to championship points is the elimination of bonus points for pole position and leading the most laps in a race.
AMA Pro Road Racing has added Section 2.30, Performance Balancing and Special Allowance, to the Race Rules and Procedures section, which states that:
“AMA Pro Racing will evaluate comparative performance every two event weekends to determine if any steps need to be taken to maintain competitive balance. If it is determined that any type or model of motorcycle gains an unfair performance advantage or disadvantage, AMA Pro Racing reserves the right, at any time, to implement restrictions or special allowances to restore competitive balance.”
Homologating motorcycle manufacturers can submit requests for special allowances if it’s believed that the machine is at a performance disadvantage and it will be processed within 15 business days. Requests for special allowances must be received 45 days before use.
Back-dating parts will be allowed in certain cases “if a part is mechanically identical between model years…but only after pre-approval by AMA Pro Racing,” whereas in previous years such practices were banned. Carbon fiber or carbon composite wheels will be allowed only in cases when “the manufacturer has equipped the homologated production model with this type of wheel,” and with approval from AMA Pro Racing.
Tire allocations have changed as well to account for two-day events. For two-day events in American SuperBike, there are five front, seven rear and one team choice (either a front or rear) slicks available; three front and four rear D.O.T. tires and three front, four rear full wet options. Daytona SportBike allows five front, seven rear and one choice of D.O.T. tires, three front and four rear in full wet. SuperSport affords three front, five rear and one choice of D.O.T., three front and three rear full wet.
The minimum weight limit for American SuperBike four-cylinder machines has been increased by 10 pounds to 380 while two cylinders must still be 370 pounds. AMA has also added the stipulation that, along with no modifications, no surface treatments will be allowed to valves, springs and retainers, pistons, piston rings, connecting rods or piston pins and clips.
The AMA is allowing “additional non-standard components” to fuel injection systems and throttle-body assemblies, “examples being but not limited to adding partial or full throttle by wire systems.” Changes to the throttle body bore and primary throttle plates are prohibited.
In Daytona SportBike, minimum weight limits for four-cylinder machines is increased five pounds to 360. Two-cylinder bike weight limits have dropped five pounds to 370.
Daytona SportBike now has a price cap of $5000 for Engine Control Systems, and the ECU “must be either: As homologated or a brand/model specific KIT system approved by AMA Pro Racing.” The retail price of a KIT ECU cannot exceed 1.5 times the price of the homologated ECU and extra components associated with KIT ECU must be on the Eligible Equipment List. Previously, ECUs could only be as homologated. The SuperSport class is also affected by the weight and ECU changes made for SportBike.
