Mine is on Gen3..but having looked at the gen4 guard front - no diff. Absolutely worth it. Your radiator(s) are different mounts. So your "impact" from detritus may be less. But on Gen 3 the large central radiator fan attracted small road chips. TWICE my bike overheated on separate rides...and when I checked the radiator I found small chips wedged between fan blade tip and the shroud. Enough to stop the fan starting.
