The DUO Ryuki 51S lure is a completely reimagined version of the original, not merely a weight-up model. With a redesigned body shape and internal structure, this new Ryuki model offers enhanced performance. The 1g increase in body weight compared to the 45S and 50S improves its handling in bait finesse techniques, allowing anglers to tackle challenging spots with strong currents and deeper waters more effectively. Despite its compact size, the Ryuki 51S boasts a strong appeal and retains the signature action that defines the Ryuki series, making it a powerful tool for anglers seeking precision and versatility.
