I don't think it would be fair to compare the two bikes. I did really like the Scrambler, but I think it had been mistreated by it's previous owner. It was a demo bike for a Triumph dealer, so had been abused by a lot of test riders, and when it wasn't being ridden, it was left outsde to rot. The reason I got it was because I fancied an old style bike, without the worry of rust and oil leaks. Unfortunately when I traded it, it had both. While it is possible to ride a bike like that off road (I've seen it on youtube!!), I'm a novice to trail riding and don't think it's the ideal bike to learn on.
The reason I chose the Tenere as my next bike was more due to the Africa Twin I used to own a couple of years ago. I really loved that bike because of the way I would have a bigger grin at the end of a ride than on any other bike I've ever owned, and that is what I'm trying to replicate again. I love the single engine on this as much as I loved the v-twin. It's popping on the over-run is bloody addictive and makes me laugh like a big kid.
What I don't like about the Ten is how easy the engine bogs down at low revs. The other two bikes are a lot more forgiving. I'm sure I'll get used to it, eventually. Also the seat is a bit rubbish (that may have something to do with the lowering that the previous owner did) and that is the main thing it has in common with the Africa Twin. The Triumph, however, had a thin seat that looked like it would be torture within 5 miles but is one of the most comfortable bike seats I've ever sat on. It almost beats the Pan European I also owned.!!!
I think, to sumerise, That I need a very large garage to house all the bikes I've already mentioned, and a few more that I haven't!!!
