The acronym «A» stands for America; this is a model which meets the requirements of the overseas market. This chassis is characterised by the rear axle’s flanges, which allow both the pitch and the height from the ground to be adjusted. In consideration of the great variety, in terms of both length and grip, of many of the tracks in America this is a crucial characteristic. Moreover, thanks to the design of the seat’s supports of 4-stroke engines of different make can also be housed. In comparison with last season, this model has many new features. First of all the bodywork is completely new; as well as having been made with 28 mm rails, its middle section reflects the line of the «R» series, which was tested by Birel’s Racing department during International races. The pull-out tank is also new, whereas in terms of fitting there are always two different versions: basic and Motorsport.
The difference mainly concerns the fact that the top version features
magnesium rims and hydraulic braking system with 200 mm ventilated disc.
