Outside of what I've already said...
I also love the feel and power delivery of the 675. I test rode one a few times and I like the way the bike "feels" better than an I4 600.
If you have a good repair relationship than that's a great start. They do require more maintanance than typical big 4 600's - the intervals are shorter for things like valves, etc.
Some of the stuff is pretty easy, it takes the same oil filters as my R1 and WRX pl14610's and things like plugs are pretty standard - I got a set at AutoZone
On the other hand if you need a gasket or something like that it will both cost more and takes longer to get. If you put the bike down it will cost you a lot more to get it back on the track than an r6 or what have you. Engine cases, forks, wheels, etc. are much more expensive and much harder to find. As an example I got a full gix front end for my SV for like $275. Just a set of fork tubes for the 675 will likely set you back $600+ There are always dozen sof for sale threads at WERA, etc. for Gix, R6, CBR, and ZX parts - take a look at how few 675 parts for sale there are. It's the same on eBay and Triumph675.net is the "big" 675 forum and there's very little there as well.
The only dealer I've really delt with on the 675 is Kissell's in State College and they are a pathetic excuse for a service department. You know the story anyway so no point in recapping it.
Little crap about the bike bothers me. The service manual is really poor (at least in comparison to the Yamaha, Suzuki and Kawi ones I have). Almost all trouble shooting has to be done with Triumph's diagnostic tool. The upside is that the bike has an OBDII port so you can read codes but the downside is that even with something like TuneBoy it's still sort of hit or miss so far as your ability to trouble shoot.
The cam chain tensioner is a weak point on the bikes but you can buy the manual version for like $50 and it's pretty easy to install if you are handy at all. The fork stop on the frames is a one-time down sort of deal. It will break off like 90% of the time if the bike touches the ground. There is also a complete vacumme system on the bike which is a pain (god only knows why).
Bodywork is not as available - Armour bodies still does not have their's out but Catalyst, Sharkskins and Rockwell have sets. I have Rockwell and it ain't all that and a bad of chips.
Vortex does not make rear sets for teh thing. Versah does not make pdas, etc. Yoyodyne is at times your only place for things like fairing stays and if you're calling Yoyodyne you'e spending money.
I still have not given up on mine and hope to get it to the track some time this season. If I do I will probably sell the gix and ride the 675 but only time will tell.
