There's a couple of things I find really interesting with the CTX1300 compared to the ST1300.
First is the number of years they built them...one! Which means getting parts for them will be a big PIA in the future, so get what you want while you can!
Next is the price they are selling NEW, (I've seen a few on ebay & cycletrader for $8,999) $9,999! Still at least $3,000 cheaper than a 2012 ST1300.
Also, on ebay I see the same shared parts (CTX1300 & ST1300), but advertised on the CTX1300 category, going for Harley prices! What's up with that?
If you like the looks and comfort of the feet forward, go for it!
