Description

The Gilera DNA is available in 50 cc, 125 cc, and 180 cc variants. It features a continuously variable transmission along with an electronic start. The 50 cc bike is limited to a top speed of 29 mph (47 km/h);[1] the 125 cc is capable of 72 mph (116 km/h); and the 180 cc bike has a maximum speed of 88 mph (142 km/h). The 50 cc engine is a 2-stroke, while the 125 cc and 180 cc models are 4-stroke, all are single cylinder.

In 2005 Gilera released the 'RST' model which replaced the handlebars with a different design and featured a new colour scheme.[2] This model was discontinued by Gilera in 2009].[when?]

The 125 cc bike was nominated for the "Machine of the Year" award by Motorcycle News in 2001.[3]
