Maybe not as much as you really can’t push the down bike underneath you. You also tend to steer more and use body weight shift less. countersteering a lot at speed.
What I am finding happens is (when its wet and slippery) is that I turn the bike in and the front just washes out. So turning left with some speed, bars to right to initiate turn to the left, as the bike tips over to the left teh front just washes out. On a solo it would be a dab and keep going but with all that weight we tend to go down.
I try and load the front tyre as much as possible. lean forward, long stem, touch of rear brake on dh turns. its always the limiting factor.
Sticky tyres are just awful for drag with all the weight. Trouble is we typically ride 30 – 50 miles mix of hard surface / tarmac and soft and slippery
