DETAILED DESCRIPTION
Extreme Glide, Uncompromising Efficiency
The Razor Line is engineered for riders who demand a pure, fluid, and continuous flight experience. This high-aspect front wing is built to deliver exceptional glide, unprecedented pumping capability, and remarkable performance in downwind and prone surf.
Power, Flow, and Precision in a Single Profile
Every detail of the Razor's design has been optimized to convert your input into pure speed and directional control. The result is an ultra-efficient Front Wing that maintains clean, stable water flow, even through the most delicate transitions. You get infinite glide thanks to its high-aspect profile, surprising pumping capability for its size, and incredible speed and control over long distances. Plus, it delivers a fluid response in carves and glides. This set includes the Blackbird Razor 1077 Front Wing, the Downwind 375 stabilizer, and the Blackbird 75 UHM mast. If you want to experiment with different fuselage lengths or use your Kraken stabilizers, try it with the Blackbird Back Tail fuselages for maximum modularity.
Blackbird Technology: Engineered to Perform
Experience superior hydrodynamic efficiency and reduced drag: the streamlined shape and monobloc construction slice through water and air, improving flow and reducing turbulence for smoother transitions, touchdowns, and rail-to-rail passages. Active Lift and trim optimization: the Front Wing generates additional lift, allowing for earlier take-off and reducing pressure on the rear stabilizer, for a flatter, faster, and more balanced ride even at high speed. Extreme structural stiffness: the aerospace-inspired fuselage design increases torsional stiffness by over 20% compared to cylindrical fuselages. Full Carbon MONOBLOC construction: the integrated monobloc connection between the front wing, fuselage, and tail ensures minimal flex and torsion, smoother transitions, instant feedback and control, and a truly connected ride feel.
Who is it for?
The Razor 1077 Integrated kit is designed for ambitious and technical riders, foilers who demand the longest glide and most pronounced pumping capability, and enthusiasts of downwind, SUP foil, and dock-start. Its expansive 1069 cm² surface area, combined with an Aspect Ratio of 11, makes it the ultimate tool for light wind conditions and extended sessions. This is also the most allround option in the Razor range, capable of excelling across five disciplines: wing foil, surf foil, pump foil, SUP foil, and downwind.

FAQ, SABFOIL RAZOR 1077 BLACKBIRD INTEGRATED KIT
Sabfoil positions the KR-1077-375-75/BB as the most versatile option in the Razor range, capable of excelling across five disciplines: Wing foil, Surf foil, Pump foil, SUP foil, and Downwind. It's recommended for Freeride, Downwind, Dock-Start, SUP, and Surf, and stands out as the Razor kit offering the earliest take-off, from just 7 to 9 knots.
While all three kits share the same M75/BB mast, the key differences lie in the FRONT WING surface area and Aspect Ratio: the 737 (648 cm², AR 8.4) is Surf-oriented, the 847 (784 cm², AR 9.2) offers allround glide, and this 1077 kit (1069 cm², AR 11) is optimized for light wind, pumping, and downwind. A larger, higher-aspect FRONT WING translates to earlier take-off and more pronounced pumping efficiency. Expect speeds of 25-27 knots for the 737, 22-24 knots for the 847, and 19-21 knots for the 1077.
Sabfoil offers two configurations for the Razor 1077 kit: the Integrated Backtail (KR-1077-375-75/BB, this kit, featuring a fuselage integrated with the Downwind 375 stabilizer) and the Modular Full Carbon (KR1077-FCM-SDW375-75/BB, available at the same price of €1899, with a modular configuration). Sabfoil confirms identical performance across both versions.
The SDW375/BB is a Sabfoil stabilizer featuring a high Aspect Ratio of 10.4, a wingspan of 375 mm, and a surface area of 130 cm². Specifically designed for downwind and long-distance pumping, it optimizes glide and minimizes drag, making it ideal for sessions where efficiency is paramount.
Yes, this complete foil kit comes with everything you need: the WR1077/BB Front Wing, a Downwind 375 stabilizer integrated directly into the fuselage, the Piantone Blackbird 75 mast, and a Carbon Rail plate with titanium inserts (CP02K/Ti). You also get the full screw set (MHQ02, MH144, MH160, MH164, MH171, MH173). All you need to add is your board.
Sabfoil offers the Cover Mast A bag (reference MA021) for the M75/BB mast, which is explicitly compatible with M63K, M73K, M73PLK, M75BB, and M76. For the Front Wing, Sabfoil offers the Cover Front Wing D bag (reference MA028), explicitly compatible with WR847, WR977, WR1077, WB800, WB1000, WR880, WR980, WRP875, WRP975, WRP1075, and W1110.
