Honda CR 500 (2 strokes)

The Honda CR 500 was a bike builted for cross and it made the history of this sport alongside her 2-strokes 500cc rivals as the Group-B did it in the rallies. It evolved with the use of an alluminium chassis, in the CR 500 AF, and a lot of riders turned their bike into monster-supermotards...

I'll let the data talk for me:

Then this bike has something like 64hp on a bike weightin 97.18 kilograms without oil and with an empty tank.
However it is still available in the United States in the 2012 version from Service Honda, and I heard that you can find it also in Europe from France or Holland resellers or maybe some used-ones from privates.
