2021 SWM  RS300R


Have you ever stopped to wonder why dirtbikes cost so much nowadays? What happened to the sport being affordable? SWM wondered that too, and they set out to do something about it when they designed the RS line.

Both the RS300R & RS500R models are 50-state street legal, ensuring that the fun doesn’t have to stop just because the trail does. But these are serious dirtbikes, with just the bare-minimum of street-legality to get you a license plate.

The RS300R/500R’s Fuel-Injected Four Stroke motors provide plenty of torque and power. And great suspension and brakes from name-brand European companies complete the package.

Isn’t it time you stopped wasting money on frills and got back to the foundations that make off-road riding fun?

Features may include:


KYB has the best-feeling suspension in the industry. RS models all feature a KYB 48mm fork and fully-adjustable KYB shock, with almost 12” of travel front and rear. They will gobble up rocks, roots, and hack right out of the box!


A Mikuni fuel injection system, controlled by a GET ECU, provides crisp throttle response, improved fuel economy, quick starting hot or cold, and the proper fuel mixture, regardless of temperature and elevation.


Brembo brake master cylinders and calipers provide the perfect balance of feel and power. They offer great modulation and feedback without being too grabby, but they still offer plenty of bite to get you slowed down from top speed in a hurry.


A radiator fan is included at no extra cost; it’s not an additional add-on like the other guys. The fan kick on when the terrain gets gnarly to keep the temps under control, giving you one less thing to worry about.
