I just put a KOSO performance steep-ramp variator and 12g sliders on my MC-23 157qmj, and what a punch! This is on of the most dramatic performance upgrades I have done to a 157, if I had known it would be such a difference, I'd have done this to my other bikes a long time ago.

Compared to a stock variator with 14g rollers;

-way snappier acceleration

- hits hills 5 to 10mph harder depending on grade ( I still recommend NOT hitting hills hard)

- Increase in top speed to 65+ on flats (hauling my 210lbs)

-rpms still reasonable, redline at 7500.
