Hi,
Congratulations on passing the test, now its time to learn how to ride!
I returned to biking after a few years away in May 2008 and bought a new F650GS. At the time I really wanted the F800GS, but at 5'7" felt intimidated by its extra height and size so went for the smaller bike.
Over the year I had it, it was excellent and couldn't really fault it at all...very comfortable, great engine, great noise and perfect for anyone new or returning to biking.
From my own point of view, I wish I'd bought the 800GS from the start. On a recent trip to Bristol Motorrad I took the opportunity to try this bike again (low seat) and, to cut a long story short, walked out of the showroom a few thousand pounds lighter.
Immediately noticeable were the following:
1) The engine seems more eager to rev and the gearing is a little lower.
2) Turning into a corner requires a little more of a shove on the inside bar due to the bigger wheel
3) As the low seat is the cut out version, I, personally, experience far less wind buffeting than on the 650GS (standard seat. but I'd fitted a stock 800GS screen as the original ise useless). I also feel that I sit in the bike rather than on top of it.
4) The bike feels it has more road presence and you have a great view over the roofs of cars.
As far as height is concerned, I have a 29inch inseem, but you do get used to it and I've had no issues. In fact, the bike is so nicely balanced, you can creep up to lights very slowly in the hope they will change before you need plant your foot.
The guys at Bristol were very helpful and will let you test ride anything. If you decide on the 650GS, they may even have my old bike in the showoom reg: PL08 HBC (i think)....Silver, ABS, Heated Grips, Clear lenses, Computer, 800GS screen. Was due to go in for a replacement warped front disk, buth otherwise faultless.
Have fun and ride safe.
