As for the size, I would say no. You will not find it bigger. As for the weight, you will find it heavier, especially at slow speed manouvers. But, it doesn't mean it's difficult to handle. When I moved from 650 to 1000 V-Strom back at 2014 I felt some extra effort needed on slow speed manouvering but it was not a big deal.
Now, if you like the power, yes, you'll notice big difference.
