Yes it will respond much quicker but the trade off will be traction or lack of contact patch at the limit.
Track guys which we are not do not increase pressure lightly. A properly inflated tire will only increase in pressure 2-3 psi.
Yes, agreed. Much of this depends on road/ambient air temperature too. But I will say that the Michelin tires feature a more complex rubber composition that within reason, allow better 'stiction' AND handling...but then they are not cheap tires either. Thus far I can already tell by a wide margin that I have gained BOTH better handling/turning/comfort and traction over the stock tires in all conditions. Even remarkably in gravel...they are better...plus the way you can 'snap' the bike into different lines on the road is amazing...and with little handle bar input... You just shift your weight...and the bike picks up almost instantly a new line...*ucking awesome!
I must though list a disclaimer, I have very little experience on a true sport bike. Logic tells me that what I'm experiencing on the Valk is very common on any true sport bike. The thing that I like about the Valk is it's longer wheel base...makes for greater stability...not having to worry to much about the front wheel coming up in hard acceleration...yet, again, remarkably...turns pretty tightly and quickly. Plus the low speed ease of balance...*ucking awesome bike!
