Depowering your kite will make it fly further forward in the window so you can head higher upwind. A race bar helps with this by letting you keep your correct body position while trimming the kite with the depower strap instead of moving the bar. High aspect ratio, race-style kites are better at this and will fly further forward in the window as you depower them.
Good avice! I ride Gaastra Jet with Ozone race bar.
Like the bar alot!
Is there a certain way of positioning your hips to point more?
