Off idle throttle sensitivity: 2018 Honda CRF450

Do you mean the power comes on hard/abrupt? Or that it surges back and forth as the power comes on?

Check the TPS setting.

Heard the 17 models had that issue & Honda reconfigured the standard map #1 on the 18's. Purchased an 18 in mid Dec. 2017 & haven't had any issues with low throttle openings. The engine performs flawlessly off idle & actually prefer the aggressive map #3 option. The bike is still bone stock at the moment & don't feel it needs an aftermarket exhaust IMHO.

What I meant is that the power comes on abrupt, not that it surges on/off. Once on the gas it's just fine, it's just when you crack the throttle open from closed is when I notice the issue.

Also to note, it is less apparent in mode 2 (mellow) and mode 3 (aggressive) than it is in mode 1 (stock).

You can always tailor a map to your liking at the initial throttle opening if you feel the standard map # 1 has an abrupt opening. From my understanding you can reconfigure map # 2 & 3, but not map # 1.
When I purchased an 09 model I do remember having that issue (abrupt throttle opening) & had it remapped which helped out due to the revised map. Your call.

I know what you are talking about. I only notice it idling around in first. Once under motion I don't notice. Think some of it for me at least, is how easy the throttle pull is. I would actually like to figure out how to make it a bit stiffer without just letting cables/barrel get dirty. Do think I'm going to try a remap.

Noticed this very thing on mine as well. Sketchy . Didnt like it at all. Bike is gone now tho . Remap should take care of it.
