I've just bought a 2009 tenere and have had a couple of XT600e's (2003) and as mentioned above, the new tenere is better in every way but the weight.
The pull is smoother and from 50-70mph there's a remarkable difference as it doesn't feel like it's straining the engine/gearbox. I used to cruise on the XT at 60-65mph but can now cruise at 80mph no bother. My old bike, a 2004 MuZ Mastiff has the XTZ660 engine and the power isn't really much different but the gearbox is, obviously.
The only bad things I can say are that the new Tenere doesn't feel as 'chuckable' as the old XT due to the weight and the styling, it's also higher, A LOT HIGHER! I'm 6'1" and still not quite foot flat down on both sides when at a stop so I'll lower it down an inch. The weight is more but waaaay lss than Africa twins and Beemers so I'll put up with it. Also the fuel injection is a bit snatchy from take off and town slow maneuvering, (something I hope to be able to recitfy by asking that question on here for a possible solution.) but under good acceleration it's a lot smoother than the XT and gets to 80+ in no time at all. I'm also fitting a higher screen (+70mm) to adjust for my height as the wind just hits me on the forehead at 60+.
So, to that end, I was looking for another XT600e for a while and didn't really think I would go for the new Tenere but one came up for a great price and I took it. Best decision I ever did!! You'll not regret it I'm sure.
Hope it helps
