About Redline Racing

Redline Racing was founded by Cameron Sawyer in 2001 and is located in Sweet Home, OR. Redline started as a small business in a garage until expanding into a 2,400 square foot shop at its original location.

After purchasing a Dynojet 188 ATV Dyno and making a little too much noise, Redline relocated to a 4,000 square foot shop just outside Sweet Home, OR. There, a full size Dynojet 224xLC was added to handle higher horsepower machines as well as Side x Sides.

Redline contains a full show room for walk in retail sales and stocks a wide variety of parts for most ATVs on the market.

While specializing in Yamaha Banshee performance, Redline Racing can modify or maintain any ATV, Side x Side or Outlaw Kart on the market. All tech work, machine work, welding, porting, boring, tuning and transmission work is done in house. There is nothing too big or too small for Redline.

Whether you need regular maintenance or a custom build, Redline Racing is your one stop shop.

Redline Racing builds and races the same motors it sells to its customers. Redline Racing motors have a proven track record backed up by winning races and dyno testing.

In conclusion your business is appreciated!
