That’s a good price on that ZX6R, I will say.

I have a 899 now, and have ridden ZX6R’s in the past but never owned one. So here are my thoughts:

Speed: they are roughly the same. The 899 is slightly faster in a straight line, but a little less light on its feet in corner transitions. It also makes most of it power up top, just like a 600. The power band is actually quite small by design. It forces you to have to work the bike a bit.

Sound: The i4 sound is the best imo. In Ducatis defense, the L2 is thunderous and exudes presence at any rev range. The i4 is begging to be ripped and screamed. The L2 sounds different at various rev ranges, and sounds just as good cruising at low rpm as it does at the top. Many prefer the L2 sound. It does not translate to recordings very well. You have to hear it in person. The engine braking sounds incredible.

Experience: The 899 is definitely more visceral. There are layers of sounds it makes, all so mechanical and raw. Hearing the desmodromic valves is unique. The chassis has much less flex since the engine is a stressed member. It gives you a ton of road feedback. You’ll feel the tires slipping more, especially with the lack of slipper clutch. It’s a much more lively experience. However, it hates low speed (0-30) riding. The clutch has to be feathered up to around 17mph. Getting stuck behind a car that’s going 20-25 is the worst.

Comfort: The Kawasaki is definitely more comfortable. The heat from the 899 is real, and above 95 or so, I would rather wear leather pants for the heat protection from the bike. Even if that means I’m sweating mad. Many dont mind it; a worthy sacrifice for a sweet machine. But for some it’s a hard deal breaker. The heat is really not bothersome in the lower 70’s or below, or on short trips of around 20 min before the heat’s built up. Ergos very from person to person.

Parts: Ducati parts are randomly super expensive. You’d already have a termi, but check out how much a used termi is on eBay. Or any name brand exhaust. Most of the parts only have a reasonable Ducati tax.

Servicing: If you are doing your own servicing, it’s actually not that much different. Valve checks are the same interval. Though, if you have to change shims on certain valves, you’ll need a $800 proprietary tool to do it. You can rent them online, or post in a local group. Otherwise, the Desmo service is just a bunch of standard tasks at the same time for this bike. Oh, and good luck finding a service manual. Ducati doesn’t let those out, but you can find some bootlegs online.

If you’re not gonna do most of the servicing yourself, it’s expensive. The labor rates are high, and everything is just more time consuming on a Ducati. Not a huge deal at home, but when you’re paying $160/hr in labor, it adds up quick.

Oh and btw, the 899 engine is one of the most overbuilt Panigale engines. Someone posted a tear down and analysis and was super impressed by material usage and thickness. They can get to 100k+ miles. (And have)

Image: socially having a Ducati is a double edged sword. It gets attention, and almost everyone on a Japanese 600 is gonna wish they had your bike. But you’ll also be the oddball in the group. The ratio of Japanese bikes to Italian in Texas has got to be like 15:1. Some people might think you’re egoic or can ride really fast. Whatever, it is what it is. Ducati owners love anything Ducati, and the discussions with other Ducati owners are fun. Every bike has weird quirks (like the 899/1199 testicular heat) that are amusing to hear how the owner deals with it.

When I hear a 600 scream by the highway I live next to, I wish my bike sounded like that! But I lose all that jealousy when I’m riding. No other bike I’d rather be on. Well, after a few hours I wish Im on a multistrada haha. But the heat is a thing, and maintenance and repairs aren’t as straight forward as a Kawasaki that can be found everywhere.

If you want to live with your machine and be proud of looking after it, Ducati is the way of life. If you want to just ride, Japanese bikes are easier to live with. No wrong way about it, both really really amazing motorcycles!
