The lap times for each class at non-Zwartkops events will be determined by the committee and communicated to the riders before qualifying at the event. If a rider exceeds the class lap time point 5.5 applies.

Riders in the Ladies and Masters classes will score points in these classes as well as classes A-E. Only points scored in classes A-E will count towards the overall championship.

5.4 If a new rider joins Bridgestone Challenge at a non-Zwartkops event the Bridgestone Challenge committee will allocate the rider to a class based on the lap times achieved by the new rider in qualifying and race 1.

5.5 A class change to a higher class will take place at the next event (unless point 5.6 applies), if during the same season a rider breaks his/her class time by lapping faster in any two different sessions (qualifying, race 1 and race 2 are defined as sessions). If a rider exceeds the class lap times in at least 4 laps in a session, then the rider will automatically move to a higher class at the next event (unless clause 5.6 applies).

5.6 If a rider breaks his/her class time but has already participated in 7 events of the season (and provided the rider does not change motorcycle), the rider will not move up to the higher class and will remain in his/her class for the remainder of the season. Example – A rider has competed in events 1 through 7 (i.e. 7 events) and at the 8th event this rider breaks his/her class time, rule 5.6 will apply and this rider will not move up a class.

5.7 A rider may apply in writing to the Bridgestone Challenge Committee to be re-classed if the rider has changed to a smaller capacity motorcycle and/or a different make of motorcycle. The committee’s decision is final.

If a first time rider does a lap time one second faster than the Class A lap time in the race, then this rider will receive a 30 second penalty which will be added to his/her race time. This will be added per race that the lap time is exceeded.

5.11 Riders that break out of class A (as per point 5.5) are encouraged to race in Sub 10 Superbikes.
