Bridgestone CSBK Confirms 2024
Kawasaki ZX-4R Cup Class Details
T
he Canadian Superbike
Championship is the latest
series that has announced it will
run a spec class for the Kawasa-
ki ZX-4R and ZX-4RR machines
for 2024.
Joining a similar venture in the
British Superbike Championship,
the Kawasaki 400-4 Cup will run
in conjunction with the updated
Pro and Amateur Twins category
on-track this season, but feature
separate scoring and results.
Pro Twins ran together with
Pro Sport Bike during their debut
season in 2023, but now they
will join the new Amateur Twins
class and the spec Kawasaki
400cc-four category to race
together in 2024.
Modifications to Kawasaki
ZX-4R and ZX-4RR machinery
will be limited, and these adjust
-
ments must fall in line with the
existing rules for the Amateur
Lightweight Sport Bike category.
All Kawasaki ZX-4R Cup compet-
itors will be required to use Gulf
Classic fuel, the lower-cost ver-
sion of two fuel options provided
by new spec fuel provider Gulf
Race Fuels.
Maximum horsepower as mea-
sured on the official series Dyno-
jet Dyno will be 75 horsepower,
checked immediately post-race.
An aftermarket slip-on exhaust
silencer will be permitted, and a
reflash of the stock ECU will also
be allowed. These figures may be
reviewed mid-season as develop-
ment continues.
As with every other category in
Bridgestone CSBK, the Kawasaki
Cup riders will have to meet a
minimum post-race weight limit
of 350 pounds.
Each Kawasaki 400-4 will run
on identical spec Bridgestone
tires mounted on stock rims.
Competitors are restricted to
two sets of tires for use over the
course of the typical three-day
event, beginning with round one
at Shannonville Motorsport Park
on Victoria Day weekend, May
17-19.
