Motorcycles Enter
the ADAS Age
by Paul Seredynski
The latest models from BMW, Ducati and KTM feature Bosch's
new ACC setup, but further advancements will require
navigating critical rider-control strategies.
and control systems advance enough to increase rider
safety without jeopardizing it.
So far, this latest tech is being sequestered to the
European makes. Ducati was the first to announce in late
2020 it would be applying the Bosch radar-based ACC
system to the 2021 Multistrada V4, along with a rearmounted radar unit to add blind-spot monitoring. BMW
will feature the Bosch ACC setup on the 2021 R 1250
RT, and the system will equip the 2021 KTM 1290 Super
Adventure S (not expected in the U.S. in its first model
year). Kawasaki previously announced it will be the first
Japanese brand to make use of Bosch's ACC tech in 2021,
but it has not yet revealed a model slated for the system.
Motorcycles finally are entering the advanced driv-
er-assistance systems (ADAS) age, dipping both wheels
into autonomous waters with the production debut of
adaptive cruise control (ACC). On passenger cars, ACC
appeared more than two decades ago, double the time
it took ABS to migrate from four wheels to two. Tier-1
supplier Bosch played a large initial role in bringing both
those features to automobiles, and is again leading the
OEM technology adoption for motorcycles.
The slower pace of ADAS feature migration to
the moto set is understandable, given the lack of
powered/integrated controls and passenger restraints,
and the far more extensive role of the rider in vehicle
dynamics. Thanks to these unique parameters, active
and intervening ADAS roles will remain limited for
motorcycles in the near term, until rider monitoring

The big snag with any motorcycle ADAS feature is the
challenge of assisting the pilot without making things
worse. Riders keep themselves aboard a motorcycle by
gripping the handlebars and bracing their legs against
the machine. Any active intervention by a safety system
that changes the attitude of the bike - without the
rider being prepared - could be disastrous. Nobody
wants a motorcycle " safety feature " that can unintentionally eject the rider from the saddle.
Thanks to Bosch's motorcycle inertial measurement unit (IMU), manufacturers now have extraordinary amounts of real-time data about the attitude of
the machine, but almost no data about the status of the
human piloting the bike. " The technology right now
