Blizzard has now chosen to do what the people wants, they are going to add the Alliance bike to Warlords of Draenor!
The difference between the Horde bike and the Alliance bike, is that the Horde bike will be free between today until 30’th of september. The alliance bike will not be cheap, it will be expensive.
Due to popular demand (and a few shady back-alley deals in Stormwind’s Old Town), the Alliance bike built for Azeroth Choppers will be rumbling its way to a vendor in Azeroth sometime after the launch of Warlords of Draenor. This mount will cost a pretty hefty sum of gold, however, so you might want to start saving up now if you want to ride around in style on this masterful machine. As a reminder, once the winning Horde Chopperis added to the game, it will be available for free to players who log in between now and September 30, 2014.
Remember, only characters of the associated faction will be able to ride each bike, so buyer beware!
