71739 Ultra Sonic Raider is based on an upcoming release.
71739 Ultra Sonic Raider is a Ninjago: Legacy Wave 5 set that will be released in June of 2021. It includes Kai, Jay, Zane and Cole in their Legacy (Dragon) suits, Legacy Golden Zane, Legacy Mezmo, Legacy Rattla, all four Golden Weapons and the Ultra Sonic Raider.
- This set is a Legacy remake of 9449 Ultra Sonic Raider. Despite being this, much of the design appears more inspired by 70595 Ultra Stealth Raider;
- The build is altered to make space for the four ninja, it is bulkier and the cockpits are different, and it lacks the small Sais on the sides, as well as the sections to place the Golden Weapons.
- The transformation feature is closer to the 2016 variant, having the middle section form into a bike and the each tread becoming seperate vehicles.
- Legacy Mezmo and Legacy Golden Zane are exclusive to this set.
- This is the third iteration of the vehicle. Much like the last two;
- This is the fourth Ninjago set to include two minifigure variants of the same character, including Zane in his Legacy (Dragon) and Legacy Golden suits, and the only Ninjago Legacy set released in 2021 with this characteristic.
- This set includes an altered version of the Constrictai Fangblade.
- A shadow of the Great Devourer appears on the box art.
- Despite being based on Season 1/2, both Zane minifigures have his titanium head.
