Duncan Butterfly XT Yo-Yo – Ball Bearing, Wide Shape, Purple/Blue, Intermediate Trick Yo-Yo

The Duncan Butterfly XT is an intermediate-level yo-yo built around a ball bearing axle that delivers significantly longer spin times than a standard fixed-axle model. With a wide, flared butterfly body, 53g weight, and 55.9mm diameter, it is designed for string tricks and responsive returns. This version comes in purple with a blue cap accent.

What makes the Butterfly XT spin so long?

The key is the ball bearing axle. Inside the yo-yo, a sleeve containing tiny metal balls allows the two halves to rotate independently from the string. This reduces friction and lets the yo-yo keep spinning much longer than a traditional wooden or fixed-axle yo-yo—up to ten times the spin time of the original Butterfly model according to Duncan. That extra spin time gives you more room to complete complex string tricks before the yo-yo needs a tug.

Design and build quality

The Butterfly XT uses a high-impact plastic body that can withstand frequent drops and hard landings. The wide butterfly shape makes it easier to catch the yo-yo on the string during tricks like Eiffel Tower or Brain Twister. A starburst response system provides a snappy return to your hand when you give a sharp tug. The yo-yo also comes apart easily—just unscrew the halves—so you can remove knots or swap the string without hassle.

Technical specifications at a glance

Who is the Butterfly XT for?

Duncan markets the Butterfly XT as an intermediate model, but it works well for committed beginners who want a yo-yo that can grow with them. If you already know how to wind and throw a yo-yo and are ready to learn basic string tricks—like Walk the Dog or Around the World—the Butterfly XT gives you the spin time and stability you need without an advanced price tag. More experienced players can use it to practice new tricks that require a long-spinning, responsive yo-yo.

Frequently asked questions

Is the Butterfly XT good for beginners?

It can be. While it is labeled as intermediate, its ball bearing axle and wide shape make it easier to learn string tricks on than a basic fixed-axle yo-yo. Beginners who are serious about learning tricks will find it a solid upgrade from a starter yo-yo.

Can I remove the string if it gets tangled?

Yes. The yo-yo has a take-apart design. Simply unscrew the two halves, remove the knot, and reassemble. No tools required.

What tricks can I do with this yo-yo?

The wide butterfly shape is especially good for string tricks that involve catching the yo-yo on the string, such as Loop the Loop, Eiffel Tower, and Brain Twister. The long spin time from the ball bearing axle also helps with tricks that require multiple rotations before returning.

What is the string gap width?

The Butterfly XT has a 3 mm string gap, which is standard for responsive yo-yos designed for string tricks.
