The Thunder Front Wing Y30 runs 5 sizes, 550–950 cm²; aspect ratio moves 7.5–8.0 across the range.
Its 660 mm span is 11% narrower than typical for the area — the median across the 65 current wings within 10% of its size is 740 mm.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
