These are Zero's own figures at their own test speeds. What you get depends on how fast you ride, what you carry, the weather and the hills. Work it out for this bike.

Chassis & suspension

Model generation
X-line · Cypher III (Gen 3)
Zero's platform generation for the machine itself, a different axis from the log-format generation our parser reports. The two do not always match: a bike's diagnostic files can decode as a different generation than its platform number.
Front fork
Telescopic front forks, adjustable preload (left fork) and rebound damping (right fork); air chamber recommended ~110 ± 10 psi (758 ± 69 kPa)
Rear shock (mono)
Rear shock adjustable for spring preload, compression damping, and rebound damping
Wheelbase
1240 mm

Brakes

Front
Hydraulic disc brake, DOT 4 fluid, lever-actuated with sight-glass reservoir (no caliper/disc size stated)
Rear
Hydraulic disc brake, DOT 4 fluid, lever-actuated with sight-glass reservoir (no caliper/disc size stated)
