The UP K2‑4 tandem paraglider is designed as a true workhorse for professional pilots and demanding recreational tandem enthusiasts, combining the agile feel of a solo wing with the ruggedness and safety a commercial platform requires.
H2: News from UP – a new generation of K2 tandem
With the K2‑4, UP has refined one of the most respected tandem platforms on the market. Feedback from tandem pilots worldwide can be summed up in one sentence: “It flies like a solo glider.” The development team focused on three key aspects – easier launch, lower weight and a carefully balanced material mix – to increase both day‑to‑day efficiency and long‑term durability.
H3: What’s new on the K2‑4?
Technically, the K2‑4 brings several important upgrades. The risers now feature a dedicated big‑ears attachment and use a combination of 25 and 20 mm webbings, delivering maximum strength while trimming excess weight. New Snaplock brake handles speed up and simplify countless take‑offs and landings. UP keeps a clear, easy‑to‑sort four‑line layout, but equips the canopy with robust Edelrid lines for intensive professional use.
Borrowing from UP’s high‑end 2‑line development, negative 3D shaping ensures a particularly clean leading edge even at high speed, noticeably boosting performance. On the upper surface, Everlast fabric from Porcher is used from the nose to 50 % of the chord, significantly increasing fabric longevity. At the same time, overall weight has been reduced by around 700 g, with the S/M size coming in at about 7.2–7.7 kg depending on configuration.
H3: In‑flight behaviour and pilot target group
On launch, the K2‑4 rises evenly without overshooting and shows a marked improvement over its predecessor, particularly in zero‑wind conditions. In the air, it offers the precise, lively handling typical of UP, encouraging efficient thermalling and relaxed cross‑country tandem flights. Optimised trimmers provide an effective speed increase and allow fine adaptation to changing conditions and passenger weights, while brake pressure remains moderate across the certified range.
The K2‑4 is primarily aimed at professional tandem pilots, yet its balanced mix of stability, performance and feedback also appeals to ambitious private pilots who enjoy XC flying with a passenger. Notably, the S/M size is certified not only for tandem but also for solo use, opening interesting possibilities for pilots who want one wing for both commercial work and personal flying.
H3: Sizes, colours and equipment options
UP offers the K2‑4 in two sizes, S/M and M/L, covering an all‑up weight range of approximately 110–230 kg and certified in the EN/LTF B tandem category. Three serial colour schemes are available, with a white underside that leaves ample room for custom branding – a clear advantage for schools and commercial operators. The standard package includes inner bag, riser bag, compression strap, repair patches and e‑manual, while optional accessories such as stuff sack, backpacks and soft spreaders round off a professional tandem kit.
H3: From specification to practice – how to proceed
If you are considering the UP K2‑4 for school, commercial tandem operations or demanding private use, it makes sense to study the full technical data, materials list and certification reports directly from the source. You can get more detailed information about the K2‑4 on the manufacturer's website and then order the complete set of equipment through Paragliding4.me, tailoring the configuration precisely to your style of work and flying.
