The shift assistant, often also called quick shifter, makes it possible to change gears while riding a motorcycle without using the clutch. This is particularly advantageous in racing, but a shift assistant also offers a high level of comfort and riding enjoyment in all other riding situations.
A shift assistant uses a spring system and a sensor to detect the driver’s shift request at an early stage and initiates the necessary adjustments via the engine control unit to enable a smooth gear change.
We offer products with either a Hall sensor or Inductive sensor technology. Our shift assistants with Hall sensors are also available in redundant configuration (two output signals).
With both sensor types, the signal output is as a characteristic curve. The switching points are normally at 0.5 V and 4.5 V. These can be adapted to customer requirements.
We offer angle joints in accordance with DIN 71805 form B (also available with matching ball stud in accordance with DIN7103 form C) and maintenance-free rod ends (connection dimensions in accordance with DIN 648 form series KA) for attachment to the motorcycle.
Currently our smallest gear assistant length is 80mm. In the future we will be also able to offer a more compact design solution with 65mm in total lengths.
The stroke per actuating direction (upshift and downshift) is 2 mm as standard. This results in a total actuation range of 4 mm. It is possible to adapt the actuating stroke to customer requirements.
The actuating forces in our current product portfolio are 180 N for the preload force (in the unactuated state) and 216 N to 260 N for the force in the end stop. Customer-specific adaptations can also be made here, but these must be checked in detail.
