Great comparison between S1KRR and M1KRR, I totally agree with your thoughts on the ability to mod the S1KRR into a better all rounder; especially for the street. A few tasteful upgrades and you can make a budget M bike with plenty of power :) It seems that these halo bikes for BMW and other manufacturers are getting pretty spendy, we need great products that the younger generation can afford 😅 It will help keep the enthusiasts and grow the sport
