They raise the front end now days? I always thought you lowered it. (I won't touch the geometry of a bike. Very delicate balance.)
Have the manufacturers gone too far in making bikes steer quickly?
The more I learn, the more confused I get.
The manufacturers don't simply raise the front nowadays.
Generally, the very steep steering tube angles of not so long ago have been replaced by less extreme ones. There's much inter-related complexity in this aspect of the geometry, mostly chassis and tires I think.
Past that, the trend for some years now has definitely been towards way more trail, and triple clamp offset is used for that.
My understanding is that this is primarily a front tire "feel" at race pace issue.
To put it in perspective, I have read that 92 mm or less of trail puts one in the "front tire no feel" zone. Meanwhile our 919's come with 98, and 110 is not out of the ordinary for road racing, be that from a current chassis or using aftermarket offset triple clamp kits.
The bigger trail numbers might also be being used to more advantageously relocate the C of G, perhaps within the confines of a target maximum wheelbase and who knows what else.
Past that, it seems to me that extremely few proponents of "raising the tubes" as a matter of course, are even aware of the also resultant reduced trail, reduced feel, and lowered C of G, none of which are advantageous in terms of serious road race track use of a motorcycle.
