The Slingshot has a tilt-adjustable steering wheel, side-by-side bucket seats, and does not lean. It has no roof, doors, or side windows and the whole interior is waterproof so it can be hosed down and drained out using drain holes in the floor.

Depending on jurisdiction, the Slingshot may be registered as a motorcycle or as an autocycle, and in certain jurisdictions the driver and passenger must wear motorcycle helmets.

NOTES from Polaris Industries:
Slingshot is a three-wheeled motorcycle, not an automobile. It doesn’t have airbags, doesn’t meet automotive safety standards, and it may handle differently than other vehicles, especially in wet conditions. Always wear helmets, and seat belts. Drivers may need a valid motorcycle endorsement. ©Polaris Industries 2019

…and where we got the name for her.

Ernie calls all the females in our family “Silly Girl”, including our puppy. Even though we had a great list of excellent names, at the last possible minute, he threw this name out there and explained how much sense it makes… so we went with it even though her official name is something else.

Her Official Name:
Via Bellator
“Silly Girl”
