Question 120/70 front tyre size, any experiences?

Hi, I'm new here. Have a 2015 390 Duke in Thailand, excellent mountain goat It will need new tyres soon, probably Michelin Power RS, and got the idea that 120/70 would be an alternative to the 110/70 but very unsure if it's good or bad for the handling. I drive almost solely twisty mountain roads and have many years of track/RR experience and want max. agility. Any recommendations, or even better, experiences?

Now we are at tyre sizes: Rear tyre could be 140/70 or 160/60 as an alternative to the org. 150/60. Any experience with that?

I run (Duke 200, 2012) 120/70 front but mainly dust roads (MT60 Pirelli).
The rear is 160/70 again MT60
The tarmac handling is noticeably less than my 390 Duke on Pirelli Rorro II (Thailand original fit 2015).
There has been a lot of discussion on this forum about the tire size for the rear and the conclusion was that although KTM sells these with 150 tires the 140s fit the rims better and as such the rubber that is in contact with the road in all conditions and corners is better than with the 150 size tires.

As long as you are happy with what you ride.

Currently running Power RS on my 2018 390 in stock sizes and very happy and impressed with grip levels and agility . I am fortunate to live in an area noted for its twisty roads .
