Customer Reviews (4.6 / 5 · 5 reviews)

Lily ★★★★★

Installed these on my YZ450F and the throttle response is noticeably crisper, especially through the mid-range. Idle smoothed out too after a quick ECU remap.

Eli S. ★★★★★

Took my YFZ450R to the dunes last weekend and the 1200cc injectors kept up with the heat and hard acceleration without a hiccup. Much crisper throttle response than the stock setup.

John ★★★★★

The install was straightforward, and the 1200cc flow rating matches what I needed for my tuned YFZ450R. Idle is steady and it pulls clean through the midrange without any hiccups, so I’m happy with how it’s performing so far.
