Enjoy that 2013 fast blue DL650....but don't get upset when my faster white 2013 comes by you in that curve!
I am like you....my bike is staying pretty much stock...the seat is not too bad at all...I use an AirHawk cushion for longer jaunts. I like the stock windscreen.... I like the wind...many of my bikes in the past had NO windscreens and that's the way I liked it. In fact, another member here is sending me his stock screen so I can cut it way down for a summer shield.
Handguards are nice for cooler weather/rainy days... so I have those, and my wife bought Suzi electric grips for me at Christmas and I definitely kept those since I ride all year round.
I did change foot pegs....the cheap rubber ones just weren't comfortable so I opted for some wider off-road style pegs. Excellent. Pricey, but a long term keeper. I'll get the name of them for you tomorrow.... most comfortable pegs I have ever had that allow you to move your feet around a LOT.
A Givi tank lock bag (15 liter, on the bike all the time) and a Bestem 44 liter trunk box (88 dollars, delivered), sees occasional use when I know I am hauling some 'stuff' back home. (I like the looks of the bike without a trunk).
No side cases for me.... I like to squeeze in between cars in front of me when necessitated by a driver behind me texting. (Makes for some interesting conversations at stoplights.
I have an old but huge and very useable MotoFizz seat bag that will hold more than sidebags anyway if need be.
The stock mirrors are good and I have yet to want to change them. At 6'+ in boots/suit, I do not get any buffeting from them. Large, rock stable, useable. I'll spend dough on something else. ;-)
So just take your time on spending. It sounds to me you like most of what came on it, OEM, as I did. (Not many of us out there if you see what everyone around here has added). :yes nod: And feel free to a ask away for any questions you may have. The search feature just above in the middle works pretty well too.
......always looking for those fast blue DL650's to go out and play with! :biggrinjester:
