I’ve got 160mm coil Lyriks with u-turn and they were no heavier than the basic coil Pikes it came with but 20mm more travel when needed and the ability to transform climbing ability by dropping front down to 115mm. Not to mention better damped travel, adjustabilty, quick to stiffen for a road section with a turn of the knob, nice and stiff tortionally etc.
However a decent set of Revelations such as the dual position ones would do all of the above up 150mm travel and weight a consderably less.
On the downhills the Lyriks are superb but when climbing of carrying the bike up mountain a lighter fork is something I ponder.
In terms of handling its fine with a 160mm fork – the manual though says that is the max travel Specialized will warranty so some of the more modern Lyriks with 170mm would invalidate your warranty.
