The ownership cost of the New duc's is greatly reduced to be competitive. The intervals are now at 18,000 miles. The panigales no longer have belts, they're chain motors, so that's even less maintenance cost. The 899 is quite a bit more motorcycle than a 675. The ergo's are similar. They're both very narrow bikes, but I believe the pani is a bit slimmer. In all honesty, I don't think you could wrong with either. See if a dealer will allow you to test ride both. There's a few dealers around Columbus that sell both. I'm not sure what triumph offers as warranty, but ducati's warranty is 2 years.
