I came from a 2010 R1 which i purchased new and put 30,000kms on her. I still have her.
Like others said the only thing you will miss from the R1 is the mid range power. When in traffic the overtaking on the R1 and its power delivery is great. But it's still a big fat heavy dog to ride.
The 899 is so agile and smooth. Getting it off the line is alot easier and more fun than the R1, also it has a smooth gearbox unlike the clunky yamaha gear boxes. The 899 will put a HUGE smile on your face everytime you get on it. Trust me you will not miss the R1's power after a few days on the 899.
I sometimes jump back on the R1 to keep the wheels turned and battery charge for a quick spin around the block and honestly i don't miss the power anymore.
So to answer your question. You will not miss the R1 at all.
It's not about how fast you ride, but how you ride fast.
