DescriptionThe whole story▼

Several distinct 300EXC variants sit on this one rear hose between 2018 and 2023: the fuel-injected TPI two-stroke, its Six Days-badged twin, an Erzbergrodeo-linked edition from 2020 onward, and the carburettor-free standard bike that arrived for 2023. All of them take a single braided rear line from Accossato, with the fitting available plain in stainless steel or painted in one of five colours.

Key Features

  • Single braided hose for the rear brake line
  • Standard S-layout routing
  • Stainless steel or painted stainless fittings in five colours
  • Aeronautical braid sheath in 20 colours
  • Covers TPI, Six Days TPI, Erzberg TPI and standard 300EXC variants

Construction and Material Quality

Accossato finishes this hose with a stainless aeronautical braid sheath and a fitting that can be left bare in stainless steel or ordered painted across five colours, with the braid itself spanning twenty shades. A single connection at the rear caliper and another at the master cylinder complete the job; the front brake line sits outside this part entirely.

TPI Fuel Injection Does Not Change the Hose

The 300EXC's move to TPI fuel injection around 2018 changed how the engine feeds fuel, not how the rear brake line is built; Accossato lists the carburettor-free TPI, the TPI Six Days, and the Erzbergrodeo-linked TPI edition from 2020 under this identical rear-only code, alongside a non-TPI 2023 standard bike. The front circuit is not part of this listing for any of those variants. A workshop should not expect the fuel-injection changeover to show up anywhere in the parts bin for this hose; TPI and carburettor bikes alike take the identical rear line, and the only real variable across this listing is the model year stamped on the frame.

Fitment and Compatibility

This hose fits the KTM 300EXC built from 2018 to 2023, spanning the TPI, Six Days TPI and Erzberg TPI variants as well as the later standard bike. Three four-strokes join it for that full span too, the 250EXC-F, 350EXC-F and 450EXC-F, while the 150EXC and 250EXC Six Days overlap only for 2023. For 2024–2025 bikes, use AGA0282.

Road Approval

Accossato documents no ABE or parts certificate for this kit, so it is intended for track and competition use.

Scope of Delivery

The kit contains 1 braided hose for the Standard layout. Connecting hardware such as banjo bolts and sealing washers is not listed as included, so it is worth checking the hardware already on the bike before starting the job. Once fitted, the circuit should be filled and bled by a competent workshop before the bike is ridden.
