JMC Motorsports is partnered with Race Tech Suspension in order to give our customers some of the best suspension parts and service in the industry.

Suspension is one of the most important parts of any machines, it doesn't matter how fast your engine is, or how much money you have into training, if your suspension isn't working then all of it is useless. JMC can get you the best suspension in the business no matter if your headed to the mountains for a weekend on you snowmobile, spending the weekend in the dunes tearing it up in your new side by side, or racing a Professional Supercross race we can handle it.

Performance Tuning

We don't just build something and push it out the door, JMC has a state of the art dyno to measure your motorcycles performance. This dyno isn't just for seeing how much horsepower your bike puts out though, we use our dyno to tune CDI boxes, adjust fuel mapping, and even find the best products to run in your machine. A little can go a long ways with performance tuning, fuel and other products can make a huge difference when it comes to the performance of your motorcycle. We take the guess work out of it all by putting in all the time and hard work to figure out exactly what will get your machine at the highest performance possible.
