Product details
Professional wheel balancer with microprocessor technology from RP-TOOLS for balancing car, truck and motorcycle wheels.

The PN series shines with its new, improved design and now supports you even more effectively in the individual work steps. The optional storage extension provides ample space for consumables, tools and accessories.

The new RP-TOOLS G2 measurement technology now delivers even more precise measurement results in the different balancing programs. Depending on the model you have a wide range of functions and balancing programs, with which you usually get each wheel balanced. The high stability at the same time you save costs when balancing the wheels.

Our machines have been extensively tested in a test phase and the quality and performance has been improved.

General Information
How often does a wheel have to be balanced?

As long as a bike/tire combination does not lose its balance, it does not have to be balanced. Mostly, however, the wheels are unbalanced after 10 to 15,000 kilometers. This is because the tire is twisted by acceleration and braking maneuvers on the rim and thereby shift the focus and are no longer in balance. Curbs also lead to a wheel needs to be rebalanced. Another common cause of rebalancing is the simple fact that balancing weights separate from the wheel and are thus no longer balanced.

Difference between Static and Dynamic
  • a) Static imbalance (up to 4 inches wide)
    A static imbalance exists when the tire has a heavy point. This could be e.g. determine by swinging out. The heaviest point would always come to a halt below.
    Smaller rims recognize the balancing machine only in static mode (because of the so-called level separation right - left).

    The motorcycle wheel is guided in the two-arm swingarm and can not stumble. It is different with the one-arm swing, here already wider rims are installed and the dynamic imbalance can occur. With special tensioning devices for motorcycle tires, it is possible to measure and balance dynamic forces.

  • b) Dynamic imbalance (from about 5 inches wide)
    Dynamic unbalance is e.g. when the tire has two heavy points that are diagonally opposite each other. This can only be determined on a wheel balancer when turning the wheel.

    Dynamic balancing prevents the wheel from "tumbling" at higher revs, so it is very important for driving from about 60 km/h. The dynamic unbalance only occurs when the wheel is turning (hence dynamic) and pulls the wheel aside.

    In extreme cases, the imbalance could be the same in both places and cancel each other out in peace. Dynamic balancing is a must have ever wide tire/rim. Dynamic balancing involves static imbalance.

4 cones

Includes four standard cones, to mount most wheels.

40mm steel shaft

Our machines have a 40 mm strong, sturdy and durable steel shaft diameter.

Pedal brake

Through an additional foot pedal brake, the wheel can be locked in the correct position during the mounting process.

High quality keypad

Membrane keypad with metal membranes.

High quality materials and workmanship

Tested with 100,000 mounting operations at full load, conforms to CE EN 1493rd.

Balancing Programs


Here, a clip-on weight is applied to the left inside on the wheel flange as well as an adhesive balancing weight to the right inside on the wheel flange.


Adhesive weights are applied to the left inside and the right side behind the spokes on the wheel flanges.


Here, adhesive weights are applied to the left inside and the right outside of the wheel flanges.


Balancing program to attach weights on the left and right side of the wheel flange.

Static 1

The Static 1 program is a procedure to balance wheel vibrations by using a single adhesive weight in the rim center.

Static 2

The Static 2 program is a procedure to balance wheel vibrations by using a single clip-on weight at the side of the rim.

MOT (Motorcycle)

Can motorcycle rims have a dynamic imbalance? Front wheel rims can have a minimal imbalance because of the narrow width. It is barely detectable while driving. Rear wheel rims with a width from about 4 inches can have imbalances but here too, only to a small extent. Which is the better way of balancing wheels, a balancing machine or the classic balancing stand? With motorcycles, only the static imbalance has a noticeable negative influence on the driving due to influences on the rims and wheel guidance, For this reason it will not matter which balance method is used. The balancer practically works the same way as the balancing stand. The heaviest point on the wheel is determined and then compensated through a corrective weight. Only with extra wide rear rims (from 4 inches) should the wheel be balanced with the balancing machine if possible, to also measure the dynamic imbalance. Tip: try to always use a balancing stand for spoke wheels. At that point you can see best if the wheel has a radial runout. If only one balancer is available, ask the technician to raise the safety cage before the wheel phase-out and check the concentricity.

Hidden spoke mode (SPLIT)

The SPLIT function enables the positioning of the balancing weights, so that they are not visible from the outside but are hidden behind the spokes.


Special ALU program for precise and fast application of clip-on weights and adhesive weights on aluminium rims. Here, a clip-on weight is applied to the left inside on the wheel flange and an adhesive weight on the right outside in front of the spokes. The position of the adhesive weight can be determined by the operator.


Special ALU program for precise and fast application of adhesive weights on aluminium rims. In this program you define the exact left and right position of the adhesive weights to be applied on the inside of the wheel flange behind the spokes.
