The R1 has a larger engine (998cc vs. 599cc) and produces more horsepower (193 hp vs. 118 hp). It also has a higher top speed (186 mph vs. 165 mph) and a quicker acceleration (0-60 mph in 2.9 seconds vs. 3.2 seconds).
However, the R6 is not without its advantages. It is lighter (410 lbs vs. 439 lbs) and more nimble than the R1, making it easier to maneuver in tight corners. It also has a shorter wheelbase (55.1 inches vs. 57.3 inches), which gives it a tighter turning radius.
Ultimately, the best bike for you depends on your individual needs and preferences. If you are looking for a pure track bike, the R1 is the better choice. However, if you are looking for a bike that you can also use on the street, the R6 may be a better option.
