Static yes, dynamic no: balancing stands like this one from Louis (99.99 euros) allow static balancing. The commuting required for this can be very time-consuming – no problem for hobby screwdrivers. Dynamic balancing is not possible with it.

Only use plastic scrapers or similar to remove old balancing weights – otherwise there is a risk of severe paint scratches.

Optimal concentricity, no vibrations

Tire-wheel combinations on the motorcycle can easily be balanced not only statically but dynamically with the help of modern technology. The Haweka experts show how motorcycle tire balancing works.

When it comes to chassis technology, motorcycles have long since caught up with the automotive sector. But when it comes to wheel balancing, the two-wheeler industry often still works like it did in the old days. The balancing professionals from Haweka (www.haweka.com) demonstrated how the same process can be carried out easily and faster to a better result using modern technology. The demonstration will be carried out by Uwe Westermann (43), Mister all-rounder at Haweka in Burgwedel, a company that has been in the balancing business for around 40 years and today with 95 employees as the world market leader for centering technology.

Professionals take five minutes, amateurs many times that

First object to be seen: the pendulum or balancing block. Something like this is available for less than 100 euros. The wheel to be balanced, including the brake disc (s), but of course without old balancing weights, is fixed on an axle via two cones and placed on the bracket. Uwe sets the bike in motion, and after a while things have settled: the heaviest point is at the bottom. Exactly across the street, Uwe puts on counterweights, and the game starts all over again. At some point there is a stable equilibrium, the wheel remains in every position. Static balancing has been successfully completed and a “Leap” of the wheel largely excluded. Professionals need around five minutes for this, amateurs many times as much.

Haweka-Tool facilitates dynamic balancing

But if, for example, the rim and / or tire have two unbalances of different weights and positions, the wheel starts to wobble and static balancing is not enough. Then balancing machines are required that can also absorb and measure occurring forces. A balancing block cannot do that, for the hobby mechanic this is the end of the story. So far, the professionals have mostly used balancing machines that were originally intended for the automotive sector (from under 1,000 to around 15,000 euros) and made do with special motorcycle clamping devices. That works quite well, but is relatively complex. In addition, the one-sided mounted shaft of the car balancing machine can cause so-called hanging errors on heavy wheels. Dynamic balancing (which basically includes static balancing) works much more easily and significantly faster with the one presented in 2015 “Bike boss” by Haweka, the world’s first motorcycle balancing device that dynamically balances wheels with a width of three inches or more.

Electronics calculate the exact position and size

The balancing shaft has a two-point bearing and the wheel is not fixed with cones but with model-specific cylindrical centering sleeves, which excludes assembly errors and corresponds exactly to the conditions in the front fork or rear wheel swing arm. The balancing shaft rotates on two attached ball bearings, which transmit forces and vibrations to force sensors. With the help of the previously entered wheel size, rim width and balancing weight level, the electronics calculate the exact position and size of the necessary balancing weights in a few seconds and display them exactly.

Time savings per bike: easily 5 to 10 minutes

That sounds complicated, but thanks to the clever menu navigation it is almost foolproof. Time savings per wheel: easily 5 to 10 minutes – and that if the balancing result is even more precise in case of doubt. From the 12-inch scooter wheel to the 23-inch enduro bike, everything that is no more than 400 mm (approx. 15.5 inches) wide can be balanced. The Bike Boss basic device costs around 1,800 euros, with centering devices it still costs less than 3,000 euros – which is rather cheap for a professional device. The customer can usually only find out whether the local tire or motorcycle dealer uses a balancing block, uses a professional balancing machine or if balancing is completely omitted. Or in the truest sense of the word through experience.
