THE REVOLUTION OF RSV4 FACTORY STARTS WITH ITS HEART: YOU CAN HEAR FROM THE
POWERFUL ROAR OF ITS 65° V-4 CYLINDERS ENGINE, YOU CAN SEE IT IN ITS FANTASTIC
PERFORMANCE ON THE RACING CIRCUIT. THE 65° V-4 ENGINE IS, IN FACT, THE MOST
REVOLUTIONARY AND, AT THE SAME TIME, THE MOST POWERFUL ENGINE APRILIA HAS EVER MADE.
With its “narrow” V-layout, a compact
engine has been created comparable
to a twin cylinder, fitting perfectly into
the chassis which, together with very
over square cylinder configurations,
are all to the advantage of power and
torque performance. Fewer vibrations
thanks to a balancing countershaft
which makes it vibrate less than a
4 in-line cylinder. By using extra light
materials, such as magnesium, its
overall weight has also been reduced.
TIMING SYSTEM AND
BALANCING COUNTERSHAFT
CUTTING EDGE ELECTRONICS
In the 65°V-4 engine, the very best mechanical
engineering, designing and engine construction made
for racing is put together with cutting edge electronics.
The Ride-by-Wire Multimap technology opens practically
infinite possibilities in controlling delivery and it is even
possible to change the bike’s “character” by selecting
one of the available mappings on the handlebar:
T - TRACK: no compromising on the track.
180HP at minimum opening of the throttle valve.
S - SPORT: fun on the road.
Electronically controlled fluid delivery.
R - ROAD: enjoyable under any condition.
Power moderated at 140HP.
The Ride-by-Wire technology is coupled with a
sophisticated electronic injection system where
a double injector is used for each cylinder and a
variable height air intake system (which depends
on motor revs) that optimises the torque level
required every second and at every speed.
