VOL. 52 ISSUE 7 FEBRUARY 18, 2015 P93
2015 is a landmark year for
World Superbike. Here's a brief
breakdown of what has changed
for 2015…
E N G I N E S
The limit on engine numbers
remains with the eminently
sensible new rule: one new
engine every two rounds, how-
ever long the championship
is, rounded up. So 14 rounds
equals seven engines per
season, 13 rounds also equals
seven engines, but 12 rounds
equals six engines.
Lots of stock parts must be
retained, whether two or four
cylinder configurations are
used, but camshafts can be
changed.
Homologated items inside the
engine must be; valves, valve
guides, rocker arms, cylinders,
pistons, piston rings, pins, clips
and crankcases. Rods may be
replaced but only of the same
material, weight—and the length
from big end to little end centers
must be the same as the stock
one. Crankshafts are now only
allowed to be 5 percent lighter
than stock, not 15 percent lighter
as before.
One set of internal gearbox
ratios all year, and a broken
gearbox equals a broken engine
for allocation purposes.
E L E C T R O N I C S
For the first two rounds the
teams can use their 2014 elec-
tronics. Manufacturers are now
making a complete 'Superbike
kit system' or a Superstock vari-
ant. Cost caps mean that you
can buy the same kit the fac-
tory team uses, plus software
and regular software updates
through the year, for a maximum
of 8,000 Euros ($9,050).
Ride by wire for bikes that do
not feature it in showroom spec
is still OK for this year and 2016.
