The KR Sport is also known as the Quannon in some
countries.
The Taiwanese Kymco has worked in the new design of the new
Quannon/KR to turn it into one nice sportive vehicle full of colors and an
aggressive design. The seducer double headlight and the 5-radio alloy turn it
into one of the preferred motorcycles by the young people.
The engine in the Quannon/KR is an improved version of the
one featured in the Kymco Zing II. Being that the Zing is a cruiser-type bike,
the engine had to undergo several modifications to fit a bike that intended to
compete in the sports bike segment. The Quannon/KR engine was thus fitted with a
chain-driven overhead camshaft driving four valves instead of the pushrods that
activated the two valves in the Zing's cylinder. This, together with various
modifications to the ignition, exhaust and distribution system, increased the
engine's power output by a little over 2 HP (from 10.8 HP in the Zing). The new
intended operating regime for the bike also required the addition of an oil
cooling system to help cope with the higher rev operation. The engine in the
Quannon/KR also includes a secondary air injection system, called SAS (Secondary
Air System) by Kymco, which together with a catalytic converter allows the
Quannon/KR to comply with EURO3 European emission standards, a requirement for
its commercialization in that region.
Quannon Naked
In October 2008, a 125 cc naked version called Quannon Naked was made available.
The naked version of the bike has been revised in several aspects compared to
the original, and now features an aluminum frame which, at 8.9 kg, is 30%
lighter than its steel counterpart. The front suspension is also made of
aluminum now, and its diameter was increased from 33 to 37 mm. The fuel tank
capacity was also increased by 1.5 liters, bringing it to 15 liters. As far as
performance goes, the gear ratios were revised, accounting for a shorter first
gear, and the rev limit was raised from 10,000 to 12,001 RPM. Also, the air
filter intake was modified to make it more silent, and the exhaust has been
redesigned and is now divided into two segments, which should make it easier to
install an aftermarket replacement. All new are the single headlight and
reworked instruments panel, which is now fully digital, sporting dual LCD
screens.
