Hi Chris,
Absolutely, the 1050 is a totally different bike. I changed from a 2005 1000 to the 2016 1000 and thought there had been a vast jump forward. I would say the difference between the 2016 1000 and the 21 1050 is the same sort of improvement. Much more useable linear power delivery, with quicker throttle response and seems to handle that much better.
I would recommend the change and wouldn't go back if I was given the chance!!
Cheers Ken
