The thing is you can’t really compare between different Pikes/Lyriks/Yaris because the positive spring volume varies with wheel size and travel (although the travel kind of cancels itself out) and the negative spring volume doesn’t change with travel although really it should.
The negative spring is bigger on the Lyrik and smaller on the Pike, so the Lyrik better suits longer travel and the Pike shorter (which makes sense as Lyriks are normally 160-180 and Pikes 120-160). Not sure about the Yari (which I thought was just a Lyrik with a cheaper damper but maybe there’s more difference?)
I have two Pikes – 160mm on the Spitfire (140mm rear with a CCDBA), 130mm on my Zero AM (hardtail). Both bikes are running pretty much the same sag on the fork, about 20%. But the 160mm fork is at only ~75psi whilst the 130mm fork is at ~100psi, which I believe is down to the larger negative to positive spring ratio with the shorter travel version (I’ve tried less pressure but it feels wallowy). I’m about 12.5 stone of moderately fast rider.
On the 160mm fork I went 0, 1, 2, 1 with the tokens, and sag varying from 15-30% before settling at one token and 20% sag. The 130mm fork came with two tokens already in it and although to my hands it sometimes feels like it ramps up a bit too much when I ride harder through my feet it feels good. Bottoms out when I huck but that’s because there’s no squish at the back.
I was really surprised how much firmer the 130mm fork feels when set up right, and how much plusher the 160mm is – I didn’t expect the 30mm difference to be so significant. I can thus see why some riders are going to 170 or 180mm up front for more aggro riding. Now I’ve got tuned into the 130mm ones I’m finding they balance the hardtail well, their firmer feel complementing the rigid rear.
