It depends what you want. I’ve never ridden a pike but the damper in that is supposed to be a lot better than the motion control in the Yari.
I’ve read the DPA Pikes / Lyrics aren’t meant to be as good as the solo air, but I don’t really understand why particularly.
The Yari is heavier and has thicker forks legs so is likely stiffer – it’s basically a lyric with a cheaper damper in it. Advantage to that is you could upgrade to a Lyrik charger damper / aftermarket alternatives if you find the Yari isn’t good enough for what you want.
The Pike is still a stiff fork though – it has the same diameter stanchions – just thinner Ines – hence the weight saving.
What fork are you on at the moment? I have gone from a Revelation with 150mm travel to a Yari with 160mm travel. So far it’s a nice upgrade – going down Pedalhounds at Cwmcarn it steered through all the roots / drop offs / rocky sections really nicely and absorbed all the hits without resorting to the last inch of travel. Happy with that as it’s there for when i really mess things up and need it.
