And , who the hell are you calling an Older Rider bro!
Well I never have much luck with those search functions pm, so sorry to be a bore. Regarding my description of old I'm thinking of myself bro, particularly relating to slow riding.
I can't even keep up with a good rider on a TR6 when I'm riding my Ducati mate, cause I just don't have that confidence I may once have had in the corners. Getting older has had experiences along the way, like hitting a Roo and breaking my arm, and many years on a Moto Guzzi that in my opinion didn't handle well, all of which lessened my confidence , but of late my Duke has been teaching me how to ride a bit better and I have applied this to my TR7 which seems to handle pretty darn well.
Thus the instructions to slightly load the front and the resulting increase of contact on the spread tyre seems to give more stability as long as you don't hit a patch of gravel. From what I gather even then you have an advantage from taking that corner in a more controlled way and I believe that if there were a sudden unexpected reason to stop you'd have a better chance. I take on board the criticism that there are many reasons where it can't help as for example when a Roo or a Deer decides to jump in your way and there is simply no way to avoid it.
I lived on a dirt road for a decade and talking with many riders about the wildlife . I discovered that the ones who had the most confidence didn't worry at all. They simply accelerated and rode over anything that presented itself. One morning I spoke with a guy who said he'd already hit 4 roos that morning and hadn't fallen once.
It's obviously not the same on a heavier road bike where hitting one of those animals will bend your forks and send you down the road sideways. In my case I bounced on the Walleroo[A heavy set animal like a stocky Roo on steroids] the bike hit the road, I hit the road and the Walleroo kept going on his merry way.
But anyway this has nothing to do with Trail Braking apart from the confidence aspect.
I'd love to hear from anyone who practises this on their old Trumpy and daily riding, their observations and thoughts on methods and so on. I believe smoothness in all functions is the key to good safer riding.
