The cost includes, among other things, a Formula 1-inspired push rod/rocker IRS rear suspension, an Infiniti G35 limited slip rear differential, a custom drive shaft, and multi-colour options for the added pieces.

The Polaris Slingshot three-wheel motorcycle is nothing if not unique. But if you want a head-turning Slingshot that incorporates four wheels, it's now possible thanks to a new conversion option from Florida-based Bullet Speed and Design.

According to Bullet Speed and Design, the relatively simple conversion features a bolt-on quad kit and requires zero fabrication. The cost is $9,999 USD (approx $13,100 CAD) for the base conversion, while an upgraded "R-Spec" kit will run you $12,499 USD ($16,500 CAD), with free installation. The company says the entire process takes a maximum of two days from when they receive your Slingshot and the schedule is clear.

The kit includes: a Formula 1-inspired push rod/rocker IRS rear suspension, an Infiniti G35 limited slip rear differential (LSD), a custom driveshaft, and multi-colour options for the added pieces.

One downside for Canadians who want to add an extra wheel to their Slingshot - unless they really love extended road trips - is that the conversion must be done at the company's Florida-based facility. So Snowbirds get ready for a road trip this winter.

Bullet Speed and Design claims that the quad setup "doesn't turn heads ... IT SNAPS NECKS," although we're not convinced it looks better than an Ariel Atom or a KTM X-Bow.

That said, adding the fourth wheel could mean prospective owners wouldn't require a motorcycle license to drive one but no official work on how law enforcement will handle the conversion.
