The motorcycle ..... History and Specs
The AX-1 & NX 250 are almost brothers , the AX-1 is the primary version, and the NX-250 is a less costly version.
Honda tried to lower the cost , and sacrificed the quality of some parts , by using common metal in parts that originally was designed to be aluminum or Stanley steel .
Lets see for start , the production time line of this motorcycles .

Next ... How On-Off is it !
Honda in Japan , had the AX-1 and one “more Off “ version of AX-1, called as Degree .
The chart indicates that the AX is Off by only 25% .
The owners of AX-1 knows very well that the motorcycle can do a lot more than what the chart indicates :-)
Another comparison .

Under this numbers, comes the conclusion , that Honda advises , that the weight of driver + passenger, or the total extra load , must be only 234 – 124 = 110 Kg .
This cause laugh to me, its hard to find a driver in Europe at 60 kg .
Any way , this numbers is here so to point that you must not overload the motorcycle , in order to have a SAFE journey , at the max. possible speed km/h.
Its well known , that when you load you motorcycle with rear top box , your max. final speed, it is advised to be at 120Km/h .
And if you use anything more, as rear soft side bags, your final speed should drops down more , as 80Km/h or less .
This is what common sense, advise as !! and the manufacturers too.
