DescriptionThe whole story▼

The HS053 kit moves the KTM 790 DUKE's clutch from cable to hydraulic actuation, using a pump built around a 13.5 mm piston, a matching hose and an AT002-64-73 actuator included in the kit. Accossato's stated aim is less effort at the lever and less upkeep than a cable clutch needs, which on a naked bike built around frequent gearchanges through tight corners is a change riders notice quickly. The kit is made in Italy and supplied complete for fitting to this specific KTM. Only DOT 4 fluid should be used once the system is bled.

Construction and Material Quality

Accossato builds the HS053 kit in Italy as a lightweight, bolt-in replacement for the standard cable clutch, rather than a heavier aftermarket conversion that adds bulk to the lever assembly. The pump's 13.5 mm piston is sized to the kit's own hose and the AT002-64-73 actuator, so the three parts are matched rather than left for the installer to pair up. Accossato's own description stresses easy installation and a design meant to minimise the effort needed at the lever, with the trade-off of very little ongoing maintenance against the periodic adjustment a cable clutch normally needs.

A Lighter Lever for a Trellis-Framed Twin

The 790 DUKE pairs a compact parallel twin with a steel trellis frame and a riding position built for quick direction changes, and that combination tends to mean more clutch use per corner than on a touring machine, not less. A hydraulic system gives a consistent bite point every time the lever is pulled, where a cable can loosen slightly over hard use and change how far the lever has to travel before the clutch engages. For a naked bike ridden the way the 790 DUKE is usually ridden, in and out of corners rather than held at a steady throttle, that consistency matters more than it would on a slower-paced machine.

Fitment and Compatibility

This HS053 listing is built and supplied for the KTM 790 DUKE from the 2018 to 2020 model years, with the fitment confirmed in the tab on this page. Accossato also offers the same hydraulic conversion for a number of other motorcycles, from BMW's F800GS to Yamaha's SR400, each sold as its own listing rather than bundled together, since the kit's pump, hose and actuator are matched to one bike at a time. Owners of a 790 DUKE outside the stated years should check the Fitment tab before ordering, as Accossato ties the kit to the specific production run named there.

Road Approval

There is no ABE or parts certificate documented by Accossato for the HS053; registration rules depend on the country, so check before road use.
