DescriptionThe whole story▼

Designed for the 2021-2023 Kawasaki KX450X, this Accossato kit is built to the Standard layout, so it replaces the factory rubber line without changing the routing. The kit is intended for riders who push the bike through motocross circuits and demanding trail terrain. Because the braid holds its shape under pressure far better than rubber, the lever firms up earlier and stays consistent from the first touch to full application.

Key Features

  • Stainless-steel fittings at every connection
  • Fittings available in plain stainless steel or painted stainless steel in red, green, blue, black or gold
  • Standard layout, following the same routing as the factory rubber line it replaces
  • Kit supplied as 1 braided hose to suit this specific layout
  • Direct replacement for the factory rubber brake line on this specific model and year range
  • Braid available in twenty sheath colours to match or contrast with the motorcycle
  • Stainless-steel braid resists the expansion a rubber hose shows under pressure

Construction and Material Quality

This KX450X kit's hose takes a stainless-steel braid built to aeronautical specification as its outer covering, built to outlast the rubber line it replaces, year after year, on every kit built for the 2021-2023 model. This kit's fittings are stainless steel, available plain or painted in red, green, blue, black or gold stainless steel, the same specification Accossato uses across its braided-hose range, not just on this model. The braid comes in twenty colour options for this kit, which gives real choice over how understated or how noticeable the finish on the KX450X ends up. As the fittings are also available painted, the whole kit's look is genuinely configurable.

Standard Layout and Hose Routing

The 1-hose Standard layout keeps the same brake-line routing that Kawasaki fitted from the factory on the KX450X, so each hose runs along the same path as the original rubber line it replaces, as built for the 2021-2023 production run. This single hose is for the front brake on the KX450X specifically, not the rear. Retaining the stock routing is the safest way to upgrade a hydraulic system, since it avoids any risk of a new hose catching on a moving part that the factory layout was already designed to clear. A proper bleed after fitting is what turns the stiffer hose into a noticeably firmer lever at the bar.

Fitment and Compatibility

Coverage for this kit is specified for the Kawasaki KX450X, covering the 2021-2023 production run in the Standard layout. The fitment data for this kit also extends to Kawasaki KX250F (2021–2025), Kawasaki KX450 (2021–2023) and Kawasaki KX450F (2019–2023), as these models use the same brake layout; the fitment tab on this listing confirms the exact match for your model and year. Because this part is specific to the KX450X, it suits a bike that is built for the demands of serious off-road use, where the brake has to stay predictable no matter the terrain.

Road Approval

No ABE or parts certificate is documented by Accossato for this kit; it is intended for track and competition use.

Scope of Delivery

Included here are 1 braided brake hose, matched to the Standard layout. As banjo bolts and sealing washers are not confirmed to be part of the kit, check your own hardware before fitting.
