Wouldn’t it be exciting and useful if you can control your Harley’s suspension setting by your smartphone? Italian suspension manufacturer Bitubo has got you covered with its latest ‘DigiShox’ Electronic Suspension System for Harley-Davidson models.

This suspension system consists of Bitubo’s proven and multi-patented ECH cartridges, its XXF rear mono shock, and a Bluetooth control unit. The control display indicates the status of the settings in use – from a choice of 12 available suspension tuning options.


A button allows the rider to choose the set-up that suits his or her riding style and load, while an E-lean drop sensor and a GPS sensor determine speed, with the value used to adapt the suspension’s setting automatically whenever required by the rider.

The Bitubo ECH cartridge kit is equipped with hydraulic adjustment of the manual spring preload and electronic adjustment of compression and rebound. Bitubo XXF mono shocks are equipped with electronic adjustment of rebound, compression and preload.

Bitubo says that using ‘the smallest and most efficient micromotors’ ever used by any suspension producer allow increasing the speed of more than 30% compared to any other similar system. The unit is equipped with 9 adjustments that are preset by Bitubo, and not modifiable, together with 3 more that can be personalized by the user.

If you want to adjust your suspension settings, just download the official app which is available for both Android and iOS. After downloading the app and selecting it, the user will be faced with the 9 adjustments preset by Bitubo and the 3 more that are customizable to suit the user. The user can then send his personalized set-ups through the application to the control unit via Bluetooth. The set-ups are selectable through the handlebar selector – parked or on the go – with a system reaction time of the system of just 100 milliseconds.
