How does RDRs work on a Harley-Davidson? – Jalopnik

The year 2020 marked a turning point for Harley-Davidson motorcycles. The iconic American motorcycle manufacturer introduced his Reflex Defensive Rider System (RDRS) on all Harley-Davidson CVO, TRI Glide, Freewheeler and Ultra models, as well as the failed LiveWire Electric Bikes, starting with the model year 2021. Het Hightech Safety system. Instead of being a stand-alone safety function, the RDRS of Harley-Davidson is a collection of intelligent traction, gear, curves and brake technologies developed to improve the safety, handling and motorcycle control of the rider, especially on challenging road conditions or in adverse weather conditions.

Harley-Davidson has since renamed his RDRS system to the longer and more confusing RDRS safety improvements, with some bicycles that get motor-specific “turns improved” functions that function differently than the stability and traction control systems found in four-wheeled cars.

All Harley bicycles equipped with RDRs have a tilation unit (IMU) to check and measure the low-fat bicycles (two-wheeled bicycles) or lateral gear (three-wheeled trikes) when turning or in the bends. The system analyzes the speed and size of the front and rear wheels while it is good for the tire contact patches. This enables the RDRS system to optimize its intervention, and it works whether the bicycle is upright or leans aggressively in a curve.

The collection of the Harley RDRS safety improvements starts with the incharis improved electronic linked braking (C-ELB). The system automatically applies the brakes to the front and rear wheels, regardless of whether the rider uses the hand lever or foot pedal to deliberately inhibit the front or rear wheels respectively.

Harley claims that the C-ELB system improves braking performance, improves responsiveness and optimizing the balance by analyzing the lean angle or lateral acceleration of the bicycle, all while the front and rear brake is changed to help the rider safely guide the bike around turns.

It works together with the curves of improved antelocrem system (C-ABS) and the improved traction control system (C-TCS) in turns to deliver a reliable stop capacity and at the same time eliminate the wheel lock. The C-TCS has two rider-selectable modes: standard mode for driving in dry conditions and rain mode for wet, smooth roads.

C-TCs can disable seasoned or professional riders to prevent the system from intervening when driving on gravel or unpaved roads or when performing glorious rear-wheel fire wheel through the cheers of friends. The Harley C-ELB, C-ABS and C-TCs all come as standard on all 2020 and later Harley-Davidson CVO models and are optionally on certain Harley Touring Bikes.

Two-wheeled Harley bicycles with RDRS safety improvements also receive a Sleep-Torque slip control system (DSCs) that prevents excessive twist of the rear wheels when writing down or rejecting, especially when crossing rain driven motorways or slippery motorways. The system can adjust the motor torque when the wheel spider detects, which improves grip and traction.

In the meantime, three-wheeled Harley trikes are getting an improved version of DSCs called C-DSCs, or in turns improved drag-torque slip control system, which analyzes lateral gear. The C-DSCS system is a standard safety function on all 2020 model year or newer Harley-Davidson Trikes, including the Freewheeler, Road Glide 3 and Tri Glide Ultra.

Completion of the list of RDRS security improvements is Vehicle Hold control (VHC) and a tire pressure monitoring system (TPMS). VHC prevents roles on slopes or sloping roads by exerting brake pressure even when the rider has released the front or rear brakes.

The system maintains the brake pressure until the driver sees the clutch and throttle when he pulled away from a stop. VHC can activate automatically when the rider retains the front or rear brake levers just after a full stop or after hard braking. The VHC indicator light on the instrument panel will illuminate when it is switched on. As for the TPMs, it actually does what you would expect – the system monitors the tire pressure of your bike and warns you if one or more of your tires need air.
