How popular is it? Not as skiing, but close. Akrapovič is from Slovenia, as you may know and he is a sort of celebrity here.
There are three to four HP4, but only two Competition or Carbon as you call it. The numbers can be different, as used bikes that are imported are not in any statistics. I know only for those bought new. The market is small, only two million people live here. In total BMW sells 300 motorcycles a year and is a top seller. Honda sells more, but small scooters and such, what we cannot count in the same segment.
Hi Moto lover. I have a Carbon as well, which I had painted red last year. I thought I was doing well at 12500 miles. Keep riding and welcome to the forum.
