Hey Sarah, I'm a bit late to the discussion, but Easter celebrations have kept me busy!! Very sorry to hear about Barney. He looked every bit part of you, and I can only imagine how hard it is to say goodbye to such a good friend.
As for the new one, talking from my limited personal experience, don't make any decision before you take a test drive on a Bonneville T 120, a Street Twin AND a Tiger 800 XR (tubeless tires)/XC (tires with tubes).
Before i bought mine, I was riding my husbands Street Twin and it's an absolute dream of a bike. It's low, it's light, it likes to do the twists and turns. Absolutely loved it. I was set to buy the new Bonneville T 120, because I liked the look, the ABS, the double front brakediscs, ... the whole package. I had all but made up my mind to go and order one.
Then I took a test drive on my Tiger 800XC and never looked back to the other models. The comfort of that bike is simply not available on any Bonneville:
- it has a high seating position (good view, easily seen by others, safety),
- comfortable (on the Street Twin I can ride for 2 hours and need a rest - on the Tiger, I have gone for hours on end and still felt fresh enough to chase my kids around),
- suspension allows you to take every bump in the road and is a huge difference with the bonnevilles;
- the bike is heavier, but you only feel that if you have to push your bike back and forth at a stationary position,
I've gotten used to that by now, it just takes a little training. Once you're riding, the Tiger is so easy to handle and it feels light.
- it's got all the creature comforts that come standard (windshield, heated grips, fog lights, protection of the motor and levers, ...); the mods on the bike are endless.
As for the height of the bike, try a lowered model, there really isn't much difference between the seat height of the ST and a lowered Tiger. I'm 1m.74 and took the first test drive on a normal high model while only having the half of my both feet on the ground. I never felt not in control of the bike, and felt immediately confident on it.
So my advice, at least try every model (T120, ST, Bobber and a Tiger) before you make any decision. Don't rule out the Tiger because of its height, because that just might not be an issue once you've tried it.
Good luck and enjoy the chase for your new bike.
