These are the draft rules for the 2 year trial period as per the 2019 AGM. These rules were posted in the members only forum for comments in early December and now posted here for all to see.
If after 2 years a decision is made to incorporate them into the rule book, they will be subject to a vote by all members. P4 Early will be subject to all current P4 rules as it is a sub-class of P4. There will be 2 classes Middleweight (600cc) and Heavyweight (750cc) which will run with the F2 and F1 classes respectively.
The classes are based on bikes available in 1983 and 1984 with exceptions listed for any bikes that continued production into later years without any changes. Here is a list of bikes we know were available in 1983-84.
