AnthonyS: My ears pricked up when I saw that you were considering Hornet 900 (amongst others). The Hornet 900 is a very good bike for the price, handles well even two up with luggage (and I was 17 stone before my crash), scratches on the back lanes and is a good commuter.
BUT, think seriously about depreciation. I never intended to sell mine, planning on running it until I died or it died...or until I'd paid off the finance. I did close to 17000 miles in the year I had mine and enjoyed every mile. It has recently been written off in an accident and I'm very lucky to be getting £4600 as the engineers quite kindly didn't push me on the mileage (the bike key went missing whilst I was in hospital). That's almost £2000 lost in depreciation in one year. Look in MCN at the second hand value of the Hornet 900. Bikes with less than 2000 miles on the clock and with extras go for around £4200.
Then look at second hand values of BMW GSs. The GS (apparently) tours better, can scratch on back lanes, has better optional extras, costs less to keep in tyres and has no chain & sprockets to replace. And if you look after it, you'll probably only lose about £200 after one year's ownership.
Knowing what I know now, if I had the chance, I'd be looking at a GS1100 for around £5000 with ABS, H/grips etc rather than £6000 for a new Hornet 900. Indeed, when I can ride again, that's exactly what I plan on doing.
You have to try all the bikes you've got your mind on, because if you don't you'll always wonder if you made the right choice, especially when something goes wrong. But unless your happy losing so much money in depreciation, think seriously whether you really want to go Japanese.......(or Italian).
