Hard for me to see how roller levers could give you a performance advantage. If they do, I would sure like to hear about it.
Let’s face it, if the clutch is holding the engine at peak torque, on the starts, and maybe coming out of a tight turn, there’s not much else it can do. Maybe just a little quicker revving up to the stall RPM, but that difference has got to be real small, and I doubt you would feel it, or see it on the stopwatch.
On the other side of that, I see no drawback except maybe your pocket book is going to be a little lighter.
