15 or 41

Would anyone know how that 1199S with the 1199R sprocket configuration (15/41 vs original 15/39) compares to the new 1299/1299S in performance, i.e. horsepower and torque as a function of rpm or, put another way, what do he relative dyne curves look like? Thanks in advance for any feedback or...

Seems to be a simple question... but this forum seems to be full of debate on it... Does anybody have the real answer????

Has anyone done the 15/41 gearing and aimed for a 540mm swingarm length. I am thinking the chain will need to be 106 links up from the stock 104 links and 15/39. Jarel, I thought I read somewhere that you had the 15/41. TX
