Fellow R3 owner here. It's Raven and badly needs an Arctic White Silk garage buddy!
I love the R3 every-which-way, and it's perfectly at home commuting in city traffic. Will I like the Italian beast nearly as well on my ride to work? Can I flick her around as well as the R3? Does she get hot in traffic? Bend you over too much to see what's going on a few cars up?
I have a feeling I won't care, for god, she is beautiful. But if you have any observations between the two I would love to hear them.
Ducati is a whole another world even when doing mundane commuting. The R3 is naturally lighter and a smaller bike so it might seem like it's easier to flick about at first, especially after your first ride on the Ducati and then getting back to R3. Once you get used to the Ducati, you will feel 100% more comfortable with leaning, splitting and generally enjoying the bike. It's a lot more planted and just as easy to move about in traffic. The heat issue is there, but it's usually just nice while the weather is coldish here in the bay. I will have to see about how it gets in the summer, although I never felt like I was uncomfortable with the heat, but you do notice it. The riding position on the Ducati is a lot more aggressive and you will feel incredible relieved as soon as you get back on the R3, but you will miss the Ducati and after you get used to it, you will prefer it. Once you get used to the rapid braking and properly manage to cling to the tank instead of putting your weight on the wrists you will be fine.
I have said that i will never take the Ducati to work or shopping runs while I have the R3.. but I find myself skipping the R3 because the Ducati is so much more enjoyable.
You will absolutely love everything from the speed to the tech, through the looks to the braking and handling and everything else. Im keeping the R3 for work as much as I can, but you should absolutely get the Ducati as then you get the best of both worlds with that and the R3.
