Changes to the Technical Rules for 2008
After consultation with all the parties involved and upon the proposal submitted by the Superbike Commission, the FIM has decided the following amendment and additions to the Superbike World Championship technical rules for 2008.
· Displacement capacities.
o 2 cylinders over 850cc up to 1200cc
o 3 cylinders over 750cc up to 1000cc
o 4 cylinders over 750cc up to 1000cc
· Minimum weights.
o 2 cylinders over 850cc up to 1200cc: 168kg
o 4 cylinders over 750cc up to 1000cc: 162kg
Minimum weight of 2 cylinders over 850cc up to 1200cc will be updated, if needed, during the Championship in steps of ±3kg to 171kg as a maximum and 162kg as a minimum.
· Air-restrictors.
Only 2 cylinders over 850cc up to 1200cc will be fitted with air-restrictors. Initial size will be equivalent to a Ø50mm circular area. Air-restrictors size will be updated, if needed, during the Championship in steps of ±2mm of diameter in a range from equivalent to a Ø46mm circular area to no air-restrictor at all.
Balance of different motorcycle concepts.
Weight limit and then air-restrictors size of 2 cylinders over 850cc up to 1200cc machines will be updated, if needed, during the Championship, by a system analysing the race points obtained.
· Tuning level.
All machines will have the same level of tuning presently applied to 4 cylinders over 750cc up to 1000cc, with the exception of connecting rods that must be standard for 2 cylinders over 850cc up to 1200cc.
· Homologation numbers.
For 2008 and 2009 all manufacturers, irrespective of their total production numbers, will have to produce a minimum of 1000 bikes in order to get an homologation.
For 2010 onwards the minimum production number will be increased to 3000 bikes.
The complete set of the new 2008 Superbike technical rules will be issued by FIM during next week.
