For over 10 years, Roaring Toyz has been responsible for some of the most creative and successful custom sportbike product innovations. Some created from scratch, others by advancing existing product categories to a whole new level of quality, excellence, engineering—and functional beauty. Made for riders with the ability and experience to appreciate and demand the qualities that make one product line stand above and apart from anything else in its class. The Roaring Toyz difference. Does this sound like what you’re looking for?

Our brand new, and exclusive, Roaring Toyz billet single-sided swingarms are advanced to a degree that has to be seen up close and in detail to be believed! Custom swingarms have been around a while. Single-sided ones, too.

These are in a whole other league.

Compared to some existing custom swingarms that show all their faults and weaknesses the closer you look, the new Roaring Toyz billet single-sided swingarm has the opposite effect:

The closer you look the more you can’t believe a swingarm can be made this well, this beautiful, this strong.

You can find a lot of swingarms that are cheaper.

You won’t find one better.

Which kind is your baby worth?
