Yamaha recently ended production of the R6 for street use in many markets and has since introduced bikes like the R7, and the relevance of 600cc supersports in today’s motorcycle landscape is still very much up for debate. There are those who insist that bikes such as the R7 are a more street friendly package with sufficient performance for most riders and those who argue nothing can replace the high revving excitement of a true supersport such as the R6. Their discussion often compares the usable performance of these different engine configurations in the real world of riding and weighs in on other factors, such as cost, comfort, and the changing tastes of motorcycle buyers. Some wrangle over whether the R6's racing use will keep the bike relevant to enthusiasts, even if it's not as practical for the street as newer designs.
