Foil Set Razor PRO 975-653-370 – Surf Foil & Fast Downwind (Mast 730 / 830 mm)
The Foil Set Razor PRO 975-653-370 is a highly versatile surf foil kit, perfect for medium-low wave conditions but capable of maintaining a high level of performance even as speed increases. The Razor PRO 975 is designed to maximize performance on waves and for faster downwind riding: it offers lightning-fast response, tight turns, and plenty of drive even during the most radical tip breaches or when returning from the crest to the base of the wave.
The set is available in three configurations: Glider ONLY (without mast), with 730 mm mast (MK/73) and with 830 mm mast (MK/83). The 73 mast offers a very direct and compact feel, ideal for prone surfing and shallower spots, while the 83 offers more clearance on chop and waves, resulting in more stability and forgiveness in challenging conditions.

Frequently Asked Questions (Q&A)
What practical difference do I feel between the version with mast 73 and the one with mast 83?
With the 73 mast, the foil is more direct and lively, you feel the wave closer to your feet and have faster rail changes, perfect for prone and shorebreak. With the 83 mast, you have more height clearance, greater stability in chop, and more confidence on bigger waves and at higher speeds.
Is the Foil Set Razor PRO 975-653-370 suitable for beginners?
It is designed for at least intermediate riders: the surface area and fast nature already require a good foiling foundation. For beginners, foils with larger and more lifting wings are more suitable (e.g., some Leviathan Easy-Riding).
Can I also use it for wingfoiling?
Yes, especially in wave wingfoiling and downwind for experienced riders; for easy and relaxed all-round wingfoiling, Medusa or Leviathan Easy-Riding kits are more suitable.
What is the Q02K quick release system for?
The titanium Q02K system allows you to assemble and disassemble the foil quickly while maintaining rigid and precise connections, ideal if you travel often, switch between 73/83 masts, or use different Kraken gliders.
