Automotive Engineering - May 2022 - 16
Two-wheeled tech:
The latest in motorcycle
applications
Drawing heavily from automotive advances, the latest in connectivity, safety and
convenience are infiltrating the moto world.

W
ith summer looming in the northern hemisphere and the
global COVID pandemic slowly abating, it's natural for
enthusiast-engineers to shift focus towards twowheeled
pursuits, including the year's latest technologies.
Trends that are altering the automotive landscape are making
similar inroads on the motorcycle front, with the SUV-equivalent " adventure
bike " morphing the sales landscape, and digital connectivity
features supplanting horsepower in the eyes of many enthusiasts as
must-have features.
With electrification making scarce OEM inroads [https://www.sae.org/
news/2018/10/harley-davidson-electrics-up], and hydrogen [https://
www.sae.org/news/2022/03/keeping-combustion-in-the-conversation]
offering a scant lifeline for combustion fans, the largest
trend in bikes is connectivity and its associated safety
benefits. According to a 2021 survey available from
Research & Markets, the motorcycle industry's connected-
technology investment between 2021 and 2027 is
expected to see a compound annual growth rate of
54.7% (from $55M to $757M). Embedded connectivity
hardware is expected to constitute the majority of that
investment, a trend already keenly visible in the market.
We've curated some of latest technology applications,
while many remain hopeful the sport retains its ability to
help riders occasionally disconnect.
2022 KTM RC wheel/brake tech
KTM has updated its 2022 range of small-displacement RC sportbikes with new, lighter brake
components and a lighter-but-stronger wheel design. This combination removed 7.5 lb (3.4
kg) of unsprung mass from the already lightweight RC 125 and RC 390 sportbikes. The allnew
braking components comprise a radially mounted front 4-piston ByBre (the " by Brembo "
subsidiary) caliper combined with a 320-mm brake rotor. The front setup is reminiscent of
engineer Erik Buell's rim-mounted perimeter disc-brake system first used on the 2007 XBRR
race bike. The KTM's single-piston rear caliper is paired with a 230-mm rotor, saving 2.2 lb
(960g) over the previous design. The new wheel design with fewer spokes and open hubs
saved 5.3 lb. (2.4 kg).
