What’s The Best Motorcycle Radar Detector? Top 6 Revealed 2021


There is no difference in the method of operation for automotive or motorcycle radar detectors. However, motorcycle owners have a couple of extra logistical hurdles to tackle in installation and use. The industry has taken strides to address many of these challenges and there is now at least one company, Adaptiv Technologies, that produces and markets a radar detector specifically for motorcycle use.

As of this writing, there is still only one motorcycle-specific brand, but many of the automotive brands have been designed with motorcycles in mind. We scoured the web forums and enthusiast pages to get an idea of the very best options on the market today. After all our research, we found six detectors that stood out from the rest. Find out more about the radar detectors that earned a spot at the top of our list

Selecting the proper motorcycle radar detector for your specific situation is crucial. We have provided the radar detection basics below for anyone in the early stages of researching motorcycle radar detectors or for those who want a refresher.

A radar detector is a small device able to detect and alert the user to radio waves or light waves commonly used by police speed-clocking equipment before they encounter the source. Radar detectors are intended to act as an early warning system allowing users a small window of time to correct their speed and driving behavior before they cross the path of the police speed-clocking gun.

Motorcycle radar detectors and automotive radar detectors are not different regarding function. The differences are largely in form. Automotive detectors are often corded units that plug into your car’s cigarette lighter and attach to a sun visor, windshield, or dashboard.

In contrast, a motorcycle radar detector will need a much more substantial mounting bracket to secure it to the handlebars of a motorcycle. It is also subject to inclement weather, so it will need to be water-resistant. Motorcycle riders are required to wear heavy safety equipment like gloves and a helmet. This gear can make set up and operation of a radar detector challenging. A motorcycle radar detector will feature controls that can be easily manipulated by gloved fingers and an alert system that can alert the driver through in-helmet audio or visual cues.

The short answer is that radar detectors detect the radio signals or light signals emitted by the two main types of police speed-clocking guns. The detector then issues an audible or visual alert which allows the rider to assess their current speed and adjust accordingly before crossing the path of the officer and their clocking equipment.

All detectors are not created equal, and neither are all police speed-clocking guns. Police radar commonly operates on three different radio bands:

  • X Band: Easily detectable by all modern radar detectors from a distance of 2 to 4 miles
  • K Band: Detectable by most modern detectors from a quarter of a mile to 2 miles.
  • KA Band: Includes KA Wide and KA Superwide bands. Lower-end detectors unable to focus tightly on one frequency or band and must continuously cycle through all.

All the motorcycle radar detectors on our top-6 list are available on Amazon, eBay, third-party resale suppliers, or direct purchase from the manufacturer. We have included a link to each detector’s Amazon page where users may learn more about purchasing options.

We started our quest to find the best motorcycle radar detector by going straight to the experts—the motorcycle riders who use them. We scoured the motorcycle enthusiast forums to get a solid handle on what worked for them and what didn’t. After we had our user-sourced list of favorite motorcycle radar detector brands and models, we studied the official specifications, testing data, and customer service policies for each. Finally, we looked at the current cost to purchase

While you can find a few entry-level detectors in the $70 range, the best models with all the features you will want (or need) will cost more. Our top six models start around $120 with most priced between $250 and $500.
