Honda has been trying to get rid of 2 strokes (2T) for the past decade and finally, in 2012 they will have achieved their goal. In 2012, MotoGP will no longer have a single 2T class. In 2010 they got rid of the 250cc 2T and 2011 is the final year of the 125cc class.
Anyway, today, while browsing the internet, I found this: 125cc Replacement Bike
