It is fine on a fire trail and out of its depth everywhere else — dive under brakes, harsh through square edges, and no way to tune any of it. Every rider ends up in the same place: the bike has the power, the front end can't use it.\u003c\/p\u003e\n\u003cp\u003eThe Ultra43 is a full replacement front end — fork legs, internals and triple clamp. ∅43mm reinforced stanchions with a DLC coating, 251mm of travel, and a symmetric left-right damping circuit so both legs do the same work instead of one leg carrying the load. Premium SKF oil seals throughout. Everything a real MX fork adjusts, this adjusts.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStanchion diameter:\u003c\/strong\u003e ∅43mm reinforced fork tubes, DLC-coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel:\u003c\/strong\u003e 251mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentre distance:\u003c\/strong\u003e 850mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping:\u003c\/strong\u003e upside-down oil damping, dual spring, symmetric left-right internals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil seals:\u003c\/strong\u003e premium SKF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper mount spacing:\u003c\/strong\u003e 78.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc size:\u003c\/strong\u003e ∅240mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLowers:\u003c\/strong\u003e AL6061-T6 CNC-machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple clamp:\u003c\/strong\u003e CNC-machined reinforced hollow clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprings:\u003c\/strong\u003e 55CRSI spring wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFasteners:\u003c\/strong\u003e zinc-nickel alloy, EU standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAdjustment Range\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-speed compression:\u003c\/strong\u003e 30 clicks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-speed compression:\u003c\/strong\u003e 10 clicks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRebound damping:\u003c\/strong\u003e 18 clicks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring preload:\u003c\/strong\u003e 17 clicks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eFits the \u003cstrong\u003eSurron Ultra Bee only\u003c\/strong\u003e.
