Whatsitgot, Mister?
The SV650 might be somewhat of a clone of the 1999
original, but there's been quite a few changes on the way
to turn it into a 21st century beast. Absolutely central to the
SV's well-being was that it would pass Euro 4 testing, and
Suzuki has managed this while increasing fuel economy and
giving you an extra four horsepower (75 hp at 8500 rpm) at
the twist grip. Torque is the same at 47 lb-ft at 8100 rpm.
Starting from the top, the new engine has been fitted with
twin-spark cylinder heads, and new, 10-hole fuel injectors.
The SV is equipped with Suzuki's Dual Throttle Valves
where there the rider controls the primary throttle body and
the secondary valve is controlled by the ECU, actuated by a
servo motor, to provide smooth power delivery at any rpm.
The airbox has been redesigned to provide better throttle
response and increase the mid-range performance via
staggered intake funnel lengths (not a variable system like
on many superbikes).
The exhaust uses a catalytic convertor and O2 sensor to
help the little SV engine pass Euro 4 emissions, having lost
a bit of weight on its own and helping increase mid-range
torque. The catalyzer is now pretty small given how big
these systems were only a few years ago.
A higher-capacity radiator now sits up the front of the
engine and is 20mm wider than the outgoing SFV650, and
the oil cooler is similar to the one found on the GSX-R750.
Transmitting the go to the road is a six-speed
transmission and wet clutch, not a slipper type.
