2.4.3.1 Balancing various motorcycle concepts
a) In order to equalise the performance of different brands of machine
rev limits will be individually applied to each brand.
b) Each season will begin with the same rev limits as the previous season
finished.
c) The rev limit will be adjusted according to 2.4.3.2.
d) Updated machines with the same basic engine design will continue
with the manufacturers previous rev limit. Any new machines entering
with a redesigned engine will have their rev limit set by calculation.
e) The initial rev limit will be the dynamometer measured rev limit of
3rd & 4th gear averaged, plus 3% or 1100 rpm above the dyno measured
max horsepower rpm of a production machine, whichever is lower.
f) The limiter in all gears will be analysed to check for anomalies.
g) The dyno test will take place during the homologation inspection.
(See Part 4.0 Homologation, 1.4.b)
h) The Superbike Commission can at any time modify the handicap system
to ensure fair competition.
2.4.3.3 Rev limit
The manufacturer specific rev limit will be adjusted in increments of 250 rpm (up or down).
The rev limit will be controlled by the manufacturers software and will be monitored by the FIM/DWO approved rev-logger (see 2.4.9.1). Over rev because of downshift will be ignored. ECU Hard limiter must be set to the WSBK specified rev limit.
