It should theoretically put you deeper (stiffer) into the linkage curve but thats my friends bike now. He is #240 and shares it with his #110 pound daughter and neither of them seem to find it too stiff. Recreational trail riders in Florida.
I suspect in more gnarly stuff where you want that initial plushness you might feel it, but their clickers are set at midpoint so Id think you could dial it in. The stock shock and fork are mucho plush on the tall setting so there is room to play for sure.
Non-Street legal setup with fluids but missing maybe 1-1.5gallon of gas:
And with street legal stuff on it, same gas amount:
Say the 'out of the box' comment because I know once I go through the bike and setup for my riding I'm adding some even more weight, the OEM tires/tubes are light, my mousse setup is heavier. OEM sprocket is aluminum, the one I swapped to is steel and that's over 1lb difference. Think I ride it at around 280lbs but like this new 300R a lot, darn good bike.
And the star of the show is that new DOHC NC300 engine:
