I had one before the GS. On a Y plate. Swapped a VFR800 for it. More usable for commuting / better riding position to see what's happening in the queing traffic.
Liked it alot - but it lacked 'character'. I only replaced it with the GS as I used to swap bikes every two years - commuting and needed piece of mind from warranty cover etc. (But I'm now into my 4th year on the 1150 GS!)
I put a MRA vario screen on it which solved buffeting at higher speeds. I liked the v-twin engine - oodles of torque. Certainly swift enough and comfy for long periods.
Like the GS - tyre choice was a big factor on usability - hated the standard dunlops!
Stonking headlights - riding a GS afterwards was a shock!
Slight flex from the handle bars (no cross bracing bar).
Watch for the rear shock - mine was replace under warranty after the remote adjuster seized. Could go a bit soft over time (dont they all)
Also linked brakes were a bit of a pain in slow traffic - not sure if the new models have fixed that but rear pedal used to apply one of the pots on the fronts?
Tendency to dive quite a bit under heavy braking

.
The Honda luggage was expensive by shaped around the exhausts provides loads of room.
I did have one low speed spill on it < 15 mph on slippery crossroads. The plastic fairing (cracked) and top box (scuffed) took most of the impact but the brake pedal bent and snapped - best part of £500 to fix !! Watch out for the plastics or better still - stay upright!
Sold it to a family member who still has it. He's about 6'4 - 6'5. and commutes (motorways) / tours two up with no probs.
He even used the rear luggage racking to rip the front wing off an over eager Ford Escort trying to knock him off at a crossroads - he kept the bike upright and only a couple of scratches on the tubing!!
