These cams made specifically to fit ODI lock-on grips tames the initial hit of throttle. This lengthens the first half of throttle input giving you more control, while shortening the last twist where you don't need the precision. This is comparable to a G2 Throttle Tamer.
I've found this combined with a good ECU map has really given me the control I was lacking on YZ450FX in the woods.
Please reference an ODI chart to verify which cam fits your motorcycle. https://www.odigrips.com/pages/odi-throttle-guide-2023?handle=throttleguide
