New Superbike Rules Coming In 2013

A series of rule changes will alter the look of the FIM World
Superbike Championship.
Several of the changes are purely cosmetic, and are aimed at making
the racing bikes appear more similar to their street bike
counterparts. Headlight decals are now required for the front of
the bikes, and the size of the sport bike tires
will be decreased from 17 inches to 16.5 inches. According to Moto
Matters, the goal of this move is to slow the bikes down as well as
to bring superbikes closer to their mass-produced counterparts.
However, preliminary testing at Aragon has many of the new machines
going as fast as or faster than the old models.
In order to improve safety regulations, new rules will be
implemented during wet races. No longer will inclement weather or
rough conditions postpone a motorsports round, unless
it is a matter of extraordinary conditions or there is an extreme
threat to safety. Instead, riders will be able to utilize pit
stops. While they still cannot change bikes mid-race like in
MotoGP, they will be allowed to change tires or make
adjustments to their motorcycle gear, Motorcycle.com
reports.
These changes represent a shift from the traditional World
Superbike to a new format, with the cause likely stemming from the
influence of Superbike's recent partnership with MotoGP. These
rules will be in effect for the 2013 season, but beyond that there
is a question mark.
