Rumbling Thunder
In Oklahoma, thunder is a soundtrack. The crackle and boom rattles the windows and scares the dogs. The ground carries it. Your teeth shake.
Thunder comes from lightning, and lightning comes from static electricity in the air “igniting” under the right conditions. When it does, the air around it heats to tens of thousands of degrees in a split second, causing the air to expand explosively, creating a shockwave.
What we hear as thunder is that shockwave moving through the air. It travels for miles even after the lightning is gone.
That power doesn’t just belong to the weather.
Before highways and fences, bison crossed Oklahoma in herds so large they shook the earth. You heard and felt them long before you saw anything on the horizon. Thousands of hooves pounding the ground beneath their feet.
Some Plains tribes spoke of the rumble they heard from bison as part of the language of the land—living power moving across it.
We can feel it in other places too.
In the arena, it's the rumble of the crowd as it erupts in a deafening roar with every turnover, block and steal. Or back-breaking three. Or dunk in transition. Or perfect mid-range jumper.
The sound of the fans rumbling into the hearts of our opponents. Living power.
After a playoff loss in OKC, former NBA player Zach Randolph said, “That crowd? Loudest I ever heard. You can't think in there.”
Take the force of a thunderstorm, the impact of a charging bison herd, and the noise of our fans packed into the arena. Now give it wheels.
That’s Rumbling Thunder Motorcycles.
