RCP-2

RCP-2 Adjustable Rear Shock – 220 × 59mm

The RCP-2 Adjustable Rear Shock is a suspension component designed for compatible rear suspension applications. Featuring a specified 220mm length and 59mm stroke, it offers rebound, compression, preload and high-pressure adjustment for configuring the suspension response.

The supplier lists two coil spring options, rated at 650lb and 850lb. These options provide different spring stiffness choices, although the correct rate depends on the suspension design, rider and equipment weight, and intended riding conditions.

For experienced electric bike builders and riders carrying out suspension maintenance, the RCP-2 offers a configurable rear shock option where its mounting and operating requirements match the vehicle.

Key Features

• 220mm shock length: Published overall shock sizing reference for checking compatible suspension installations.
• 59mm shock stroke: Specified damper stroke, not guaranteed rear wheel travel.
• Rebound adjustment: Provides a setting for controlling how the suspension returns after compression.
• Compression adjustment: Allows changes to the shock’s resistance during compression.
• Spring preload adjustment: Supports initial spring loading and appropriate suspension sag setup.
• High-pressure adjustment: Listed by the supplier, with the operating method requiring technical confirmation.
• 650lb and 850lb spring options: Two coil ratings are listed for selection according to compatible suspension requirements.

Rear Suspension Performance

A rear shock absorber controls suspension movement as the wheel responds to changing terrain. Correctly specified suspension components help the motorcycle or bicycle maintain appropriate movement and control over bumps and uneven surfaces.

The RCP-2 is offered with multiple adjustment functions, allowing the damping and spring setup to be configured for the intended application.

Actual handling depends on the complete suspension system, including frame geometry, linkage design, spring rate, damping settings, tyre characteristics and rider weight.

The supplier does not publish independent suspension performance tests or comparative handling measurements.

Rebound and Compression Adjustment

Rebound damping influences how quickly the suspension extends after being compressed. A suitable rebound setting helps the rear suspension recover in a controlled manner between successive bumps.

Compression damping influences the suspension’s resistance as the shock compresses. The RCP-2 provides a compression adjustment function, although the supplier does not specify separate high-speed and low-speed compression circuits.

Both adjustments should be configured according to the shock manufacturer’s instructions and the requirements of the vehicle.

Spring Preload and High-Pressure Adjustment

The RCP-2 includes a preload adjustment function. Preload can be used as part of the suspension sag setup, but it does not change the spring’s inherent stiffness or compensate for an incorrectly selected spring rate.

The source also identifies high-pressure adjustment without explaining the associated mechanism, permitted pressure range or servicing procedure.

Do not attempt to charge, release or alter pressure in a suspension component without the manufacturer’s instructions and suitable equipment.

650lb and 850lb Coil Spring Options

Vector E-Bike lists 650lb and 850lb coil spring options for the RCP-2. The available ratings give customers different stiffness choices when planning a compatible suspension setup.

The correct spring selection must account for the motorcycle’s suspension leverage ratio, total supported weight, desired sag and intended operating conditions.

The product listing does not identify which spring is supplied by default or confirm whether both springs are included. Buyers should verify their selected spring before ordering.

Dimensions and Installation Compatibility

The RCP-2 is specified with dimensions of 220 × 59mm, equivalent to approximately 8.66 × 2.32 inches. These values are relevant when comparing the shock against the requirements of an existing suspension system.

However, matching length and stroke alone does not establish compatibility. Mounting eyelet dimensions, bushings, hardware widths, frame clearance and suspension linkage requirements must also be checked.

The supplier does not identify a confirmed list of compatible Talaria, E Ride Pro, Sur-Ron or Vector models.

Before installation, compare the shock against the vehicle manufacturer’s suspension specifications. Incorrect sizing or fitment can affect suspension travel, component clearance and vehicle handling.

Why Choose the RCP-2 Rear Shock?

The RCP-2 combines a documented 220 × 59mm shock size with rebound, compression, preload and high-pressure adjustment. The availability of 650lb and 850lb coil spring options provides an additional specification to consider when selecting a suspension setup.

For customers in Germany, this shock is worth evaluating for a compatible suspension replacement or custom project where the required mounting measurements and spring selection can be confirmed.

Its suitability should be established using technical fitment information rather than assuming universal compatibility with electric dirt bikes.
