Harley RDRS Problems – Identifying Issues With The New System

In 2020, Harley Davidson unveiled the Reflex Defensive Rider System (RDRS), a revolutionary new technology specifically created to optimize motorcycle performance. RDRS is able to adjust and fine tune handling based on available traction during acceleration, deceleration, and braking – ensuring you get maximum control from your ride.

RDRS is a sophisticated safety technology that helps riders better manage their motorcycles on risky roads or in urgent situations. It adjusts accordingly for low traction and even indicates when tire pressure needs to be addressed.

In this article, we will dive into the intricate details of the cutting-edge RDRS systems as well as examine some Harley RDRS problems encountered by riders using it.

Advanced Braking

RDRS is equipped with several cutting-edge braking technologies, such as Anti-lock Brake System (ABS) which prevents wheel lockup during deceleration to ensure maximum control. Cornering Enhanced ABS (C-ABS), a specialized variant of the former system, adjusts cornering and tractive forces at the contact patch while in combination with brakes to offer an extra level of stability.

Electronic Linked Braking (ELB) enhances your riding experience by simultaneously activating the hand lever (front) and foot pedal (rear). This feature helps you brake more effectively. Plus, Cornering Enhanced Electronic Linked Braking (C-ELB) takes into account the motorcycle lean angle or Trike lateral acceleration to provide additional control when braking around corners. All of these systems work together seamlessly for a superior performance every time.

Traction Control Systems

The RDRS system features several cutting-edge traction control technologies. C-TCS, which stands for Cornering Enhanced Traction Control System, specifically prevents the rear wheel from “spinning out” when accelerating while leaning on a motorcycle.

This system gives bikers the control and assurance they need, especially in wet or icy conditions. Drag-Torque Slip Control (DSCS) works to reduce rear wheel skidding when riders abruptly downshift their gears or gradually brake on slippery roads. The Cornering Enhanced Drag-Torque Slip Control System (C-DSCS), which is based off of detected lean angle, further bolsters this action while cornering. With DSCS & C-DSCS working together, riders can experience greater stability with every ride.

Vehicle Hold Control

Vehicle Hold Control (VHC), also known as Hill Assist, is a revolutionary system that uses brake pressure to keep your motorcycle from rolling when starting on an incline. Making it easier and safer than ever to start off on those difficult hills, bridges or parking ramps.

Tire Pressure Monitoring System

With the RDRS system, there’s no need to get down on your hands and knees anymore. Its Tire Pressure Monitoring System (TPMS) constantly checks the air pressure in each tire while you drive, so if it falls below a certain level, it will alert you right away. This revolutionary technology makes monitoring your tires an effortless task – keeping both riders and their vehicles safe.

Harley RDRS Problems

The RDRS system offers plenty of advantages to riders, however some have expressed difficulties using the system. For example, one rider encountered their own set of Harley RDRS problems while riding: they were unable to get any VHC working, and witnessed a continuous ‘TC’ light illuminated on their ride. Despite attempting various techniques in an effort to resolve this situation, no relief was achieved by that rider.

Another rider encountered Harley RDRS problems and reported a fault in the ABS system, causing their traction control and hill assist to cease functioning. After numerous attempts to resolve the issue were unsuccessful, they realized they were no longer covered by warranty due to previously installed Fuel Moto modifications such as cams, pipes, intakes, and tunes. These are only two of many difficulties riders have encountered while using RDRS technology.

Tuning with RDRS

When it comes to Harley RDRS problems, riders often make missteps. One of the primary errors is loading a non-RDRS Power Vision calibration into an RDRS equipped bike – this causes all sorts of engine codes and incorrect RDRS operation. Another frequent mistake is deactivating Torque Based ETC in a Power Vision RDRS tune; unfortunately this also leads to many problems regarding engine codes and faulty functioning of the system itself.

Moreover, another frequent misstep is adjusting a cam or big bore application by using an original tune created for stock power levels (a Stage 1 type tune), which diminishes engine output since the torque model does not correspond with the motor’s performance. In certain situations, riders have made numerous of these mistakes within a single tune – thus leading to multiple Harley RDRS problems .

Harley RDRS Problems In A Nutshell

To sum it up, Harley Davidson launched the Reflex Defensive Rider System (RDRS) in 2020 with a range of cutting-edge braking and traction control features, along with vehicle hold control and tire pressure monitoring. Although RDRS offers several advantages to riders, some have encountered Harley RDRS problems while using the system.

RDRS can bring a range of issues to your motorcycle including ABS faults, traction control and hill assist malfunctions. Therefore, it’s essential for riders to understand the system thoroughly in order to tune their bike correctly; failure do so could lead to hazardous road conditions.

Additionally, understanding how the system works is paramount in helping keep you safe when riding on any terrain type – ensuring that all systems are up-and-running as they should be.


Below are some frequently asked questions (FAQs) related to Harley RDRS problems:

What is RDRS, and how does it work?

RDRS, or the Reflex Defensive Rider System, is a comprehensive set of technologies developed to keep motorcycle performance in sync with available traction during acceleration and deceleration as well as braking. This impressive system provides riders with advanced brakes, vehicle control management systems for greater stability, tire pressure monitoring tools and much more.

What are some of the reported Harley RDRS problems?

Several motorcyclists have been faced with ABS faults, traction control irregularities, and hill assist malfunctions. Additionally, some riders have encountered difficulties pertaining to the RDRS system specifically.

Can tuning affect the RDRS system?

Absolutely, tuning can have an impact on the RDRS system. If careless errors such as loading a non-RDRS Power Vision calibration into an RDRS bike or disabling torque-based ETC in a Power Vision RDRS tune occur, engine codes and malfunction of the entire RDRS are likely to come up.

Can I still tune my motorcycle if it has RDRS?

Absolutely, you can still adjust the settings of your motorcycle if it has RDRS, yet make sure to use the precise tune that goes hand in hand with this system. When unsure about what fits best for your bike and its RDRS setup, seek aid from an experienced tuner.

Is RDRS a reliable system?

Ultimately, RDRS is a dependable system that ensures rider safety while on the road. Although some issues have been reported every now and again, they are rare cases which means most riders experience highly positive results with the RDRS system in place.

What should I do if I experience Harley RDRS problems?

If you’re experiencing any difficulties with your RDRS motorcycle, it is of the utmost importance that an experienced professional technician inspects and evaluates it. Never attempt to diagnose or resolve issues on your own as this could easily lead to further complications and severely impair your safety while riding.
