Hi, I have got this bike for a year now, funny machine I must say. Very nice to roam around. But a little too weak engine to catch some wind (well, it needs an overhaul I presume) - I am only afraid if it is not this ´redced effect´ version. Anyone has any info how to distinguish between those two options? I heard about it just minute ago on this site.Is this generic modification or only custom setting for A1 license, done to original factory version?
