Here some food for though and I would appreciate others ideas on the topic.
I have been thinking about the topic of forks and cornering.
I have heard tell that raising the fork stanchions up through the top steering yoke by 20mm improves the turning in (Steering) on a motorcycle, doing this lowers the front of the motorcycle by that amount, now does lowering the front of the bike by 20mm improve the handling? I can't see it myself, what else it does do is effectively shorten the bike by that amount, now I can see that making a difference to the turn in on a motorcycle, a slightly shorter wheel base.
I have also read that by raising the forks (Lowering the bike) by 20mm causes the bike to be a little less stable on the straights at higher speeds.
If this is true there is a trade off going on here, slightly better steering for sightly worse straight line stability.
Now when approaching a bend we knock the bike down one or maybe two cogs and gently brake to reduce our speed to a safe pace to take the corner, now very gently, and I mean gently hold the front brake a little longer into the bend will cause the bike to dip slightly on the front forks, effectively lowering the front of the bike, or if you prefer shortening the bike as we approach the apex of the bend.
It seems to me that has exactly the same effect as raising the fork stanchions (or lowering the bike) but that shortening it is recoverable as soon as we let go of the front brake lever so there is no compromise to the straight line handling or stability, so as you start to apply power coming out of the apex let the front brake lever go as well
at that point, bike rises with the power and bike is now at it's maximum length and straight line stability is returned in full.
Wot-ch-fink ?
