Engine

The engine in the Quannon 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 engine was thus fitted with a chain-driven

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 also includes a

Variants

Quannon 150

A 150 cc (62 mm×49.5 mm, 149.4 cc) version of the bike was released in primarily in the US and some other selected markets, featuring an extra HP compared to the 125 cc version, taking it to 14 HP. While the 125 cc model did not get official distribution in the United States, being mainly sold in Europe, the 150 cc was brought to the U.S. market in the form of the Kymco Quannon 150 for 2010. Sales were very poor for this variant and it was quickly discontinued. Therefore, the 2010 model was the only year that the Quannon was sold in the U.S.

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
