CUSTOMER REVIEWS
“We have been using the PLEX SDM-550 for vehicle development including engine calibration, brake testing, and suspension tuning. The small packaging and capabilities make these units ideal for on-road motorcycle testing compared to other systems that require more mounting real estate to communicate multiple data sources.”
BUELL MOTORCYCLES.

“It helped me to log and show important values and alarms in modified street/race cars. It also helped me to understand and improve car performance. Very valuable built in GNSS!”
LUKAS R.
CZEC
“The LCD screen is super bright and colors are vivid. The anti reflective glass screen makes a huge difference as well. Once you’ve seen how well it works, it’s difficult to accept anything that doesn’t have this AR coating. Software is quick to get familiar with and everything is super configurable. It does everything right!”
KURT C.
TX, USA
“The best thing for us is the direct connection to the CAN bus. We can log all our data and in combination with the GPS tracker we can learn a lot. We have already used it to improve our suspension setup, detect problems in our electrical system and train our drivers. So for us, the SDM-550 is not just a display that you can easily customize, it improves our performance on the track and our knowledge of the car!”
RUHR UNIVERSITAT
Bochum, DE
“We’ve worked with Plex Dash for many years and can provide our customers exactly the dash they need for various race series, each with its own specific requirements. The system’s biggest advantage is its flexibility: we can create fully custom pages, use pop-ups and colors, and easily integrate everything with a simple CAN configuration. Best of all, there are no locked features—everything is accessible at any time, including a built-in data logger with user-friendly software.”
