Mistress Motorsports started with two passions becoming one. Our owners Rampsey “Seth” and Mercedes Nicholson make a perfect match for this business. They have a true passion and drive for the off-road world.
Mercedes Nicholson (McClintock) has always been a part of the industry from a young age. She began racing ATVs at 8 years old on a national level, bringing home many awards. She raced the Extreme Dirt Track National Series for many years. She decided to take a break from racing in 2011 and attend WyoTech in Daytona Beach Florida to obtain a motorcycle mechanic certification.
Mercedes also obtained an Associate's Degree in Business Management and Service Management. Mercedes possesses a true love and passion for the off-road industry, from racing to riding RZR on the weekend with her husband and friends.
She hopes to be able to get back into racing Nationals after her children are older and become involved in the sport!
Rampsey “Seth” Nicholson is also a true enthusiast for the off-road industry and sport. He also has raced motocross events, but his true passion lies within building custom machines, turning wrenches and working hands on. Seth enjoys stripping machines down to a bare frame and building from the ground up including powder coating, rebuilding the engine and accessorizing to make it look brand new!
Seth at a very early age started working on his own machines which turned into a “hobby” of buying and selling used machines.
Today, Seth builds custom machines, wrenches on machines, and buys/sells used machines. You can find Seth in the shop daily behind the parts counter or in the bays turning wrenches.
Making Your Off-Road Dream Become a Reality.
We are here to offer enthusiasts, racers and the people who get things done, the best aftermarket ATV, UTV, and Dirt Bike parts and accessories at the best prices. We are here to get you up and running after a breakdown and we are here to offer a lifetime relationship with our customers.
Family owned and operated. We are fortunate enough to share our love for riding and the drive to build machines to run, perform, and look better with YOU. We’re known to load up our trailer on Friday in anticipation of the weekend. Come Saturday, we head to the local track, a national event or the trails, joining our family and friends. To us, riding isn’t just a hobby. It’s a part of who we are.
Our goal is to offer you the utmost satisfaction. We strive to help you answer any questions you may have and find the right part or accessory you need. WE take pride in our work and want you to keep coming back.
With Mistress Motorsports, our knowledge of the off-road world allows us to offer the best customer service experience. We are here to help whether it is a part or accessory that you need, an oil change or a complete overhaul on your machine – you can count on us!
“I have been doing business with Seth for over two years. From servicing my Polaris 570 to the kids dirt bikes. He is very prompt on responding to anything I have needed. Voltage regulator, rear axle, to a new oil pan! Great service and pricing. And flexible pickup as I am not local”
