Quick shift system
The quick shift system allows for full-
throttle, clutch lever-less upshifts.
When the shift switch detects motion
in the shift pedal, engine power and
drive torque are momentarily adjusted
to allow the upshift to occur.
TIP
The quick shift system operates when
traveling at least 20 km/h (12 mi/h) with
an engine speed of 2000 r/min or high-
er, and only when accelerating. It does
not operate when the clutch lever is
pulled.
NOTICE
ECA26260
To prevent drivetrain damag e, al-
ways use the clutch lever to shift
when ri din g at slow spee d, when
d ownshiftin g, or if the quick shift
system is off.

Ig nition circuit cut-off system
This system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will
stop the running engine should the
sidestand be lowered while the trans-
mission is in gear.
Periodically check the system via the
following procedure.
TIP
 This check is most reliable if per-
formed with a warmed-up engine.
 See pages 4-2 and 4-4 for switch
operation information.
