Yes, the Stock 140 and Stock 160 pit bike classes are very popular and we regularly have up to 60 entries each for these classes. To make sure that everyone is safe but also so that they all get a chance to race in the same championship we run a split grid system.
During Practice and qualifying we separate out the entries into 2 Groups based on ability, this is done by the Race Director prior to the meeting, taking into consideration the riders previous finishing positions and also their personal knowledge of the individual riders etc. The slower riders will be placed in Group 2 and the faster riders in Group 1.
The lists of riders that have been allocated to each group will be published in the Riders Pack emailed to all entered riders and also will be on display at the circuit.
The riders will Practice and qualify in the groups they have been allocated to. Once Qualifying has taken place the times for the two groups are merged together and the faster riders will Race in Group A and the slower riders Race in Group B.
A rider who wins Race 1 in Group B has the choice to join the back of Group A for Race 2. This allows them to race for the higher point-scoring positions and also allows the faster riders that have had a bad qualifying session to still recover into Group A for Race 2.
In these big grid classes, we run points from 60 for 1st place down to 1 point for 45th. This means the riders in group B are still racing for championship points.
This system is extremely flexible and allows all to take part in the championship fairly whether there be entries enough for 1 group of two.
