Mine is one of the early ( first ) cheap no frills models no G spot button, but still handles OK on the two green lanes i have done. I will not be doing any green lanes again unless i am lost..but i can say i have done it just to point a finger at the people who derided the bike when it first came out from what my dealer told me it is a sort of traction control device to help in slippy conditions, road or lane.
