Picked up my K9 650 about 3 weeks ago and thanks to lots of good information here, I'm slowly getting it set up the way I want for sport touring. The bike had 500 miles on it and came with Givi Bars, front fork stabilizers, Madstad, and Givi bags (E21x2 and V46).
First thing I did was an even swap of the 650 seat for a DL1000 seat with a forum member. Cost to me was one way shipping, about $20. That seat will last me until I get a custom seat built. Still deciding on that. May try a gel seat first.
Second change, Kaoko throttle lock. I chose it because it looks integrated. Also notice the grip puppies.
Formotion oil-filled thermometer. A ruggedized scientific instrument that will last longer than the bike.
Bags-Connection Engage tank bag, mounted on SW gas cap mount. Nice.
Factory handguards. Again, looks integrated, provides cold weather riding protection. Not looking for tip-over protection from these.
Powerlet rearset kit. Looks integrated, perfect location for heated gear.
De-badged the chrome "s" off the tank. Just didn't look coherent with the rest of the tank decals. Looked like it should be on a sport bike not an adventure bike. Also notice the Suzuki center stand. Easy install except the springs, but doable thanks to tips on the forum.
Still to come, possibly a MRA VarioTouring screen (short) although I've been pleasantly surprised at the stock screen on a Madstad. Done 400 mile days on it with relative comfort. Possibly daylong or gel seat. That's about it.
Total cost of farkles so far about $650. Since selling my BMW I've sold about $500 in BMW farkles so I'm only down about $150 at this point. One of the reasons I switched from BMW was to save money and as part of that I am not going to go hog-wild on farkles, just the basics here so my total investment including used bike (if you call 500 miles used) which came partially farkled at $5900 and other farkles at a few hundred, I'm under $7000 for a like-new and very competent and entertaining sport touring/adventure bike. I already did the first service myself which saved me about $400 off what servicing my last bike would have cost.
