There are three generations of Versys:
2006-2009 MK1, solid mounted engine. I think all years were the same, save for a change in the master cylinder, can't recall when they changed it.
2010-2014 MK2, rear rubber mounts, hollow rubber footpegs. Suspension is the same, revised spring/damping. Same engine. ECU is updated, power characteristics remain the same.
2015+ MK3, all rubber mounts in the engine, rubber footpegs, rubber mounted handlebar, larger fuel tank (2 extra liters, a bit more than half US gallon), updated suspension, new brake calipers, and it finally shares the engine with the 2012+ Ninja 650.
They all are basically the same 2006 bikes with some updates. The hollow rubber footpegs can be mounted on the MK1, and I suspect that the handlebar setup of the MK3 will fit the MK1/2, but it's too early to tell.
In the US ABS is only available on 2014+ bikes, I sold my 2010 to get a 2014 with ABS. In theory you could install ABS on a bike without it, in the real world you're better off buying a bike with ABS, it's too freaking expensive.
