BMW WSBK
team chooses
Supersprox
BMW returns to the World Superbike
scene in 2019 with an official factory
team, managed by UK based SMR
Racing. The 2019 bikes will be piloted
by Tommy Sykes and, coming from a
dominant win in European Superstock
1000, Markus Reiterberger.
BMW will use Supersprox sprockets for
the factory machines - “further
solidifying the relationship between
BMW and Supersprox, who have
supported the BMW development
team in the German IDM series”.
Supersprox General Manager DJ
Maughfling says: “We have been
working hard to develop sprockets
with better chain disengagement
performance. Traditional sprockets
tend to be thin and weak at the tooth
tips, because they follow DIN/ASA/JIS
standards from the turn of last century.
Today’s bikes have over 200 bhp and
traction control, delivering new levels
of power through the final drive.
“Our highest performing sprockets
have shallow angles at the tip of the
tooth and larger diameters for the
rollers. This helps reduce friction and
heat build-up in the chain - we all
understand that friction reduces
power, and, in this situation, less is
certainly more.”
Maughfling says that with a view to
finding the optimum performance,
whilst maintaining the strength,
Supersprox will be testing different
compounds throughout the 3-year
contract, and variations will include
the dual material Supersprox-stealth
and even a carbon fibre composite
with aluminium teeth and a carbon
core.
Supersprox is well known as the
inventor of the patented hybrid
sprocket, combining steel teeth and
aluminium core. In 2018/2019, the
company gained a further five
additional world titles including the
World Endurance Cup and the Dakar
Rally, both using the Supersprox-
stealth original design.
