DescriptionThe whole story▼

This Accossato hose covers the Yamaha WR450F across two separate production spells, 2007 to 2015 and 2019 to 2022, replacing a single rubber brake line with aeronautical braid along the factory's own routing. The 450 is the harder-hitting end of Yamaha's enduro range, and riders who push it through demanding terrain put real load through the brake lever on every descent, which is where a hose that has not softened with age earns its keep. A big-bore enduro bike like this one puts real load through the lever on steep, technical descents, and a hose that has not softened with age makes that load easier to judge precisely.

Key Features

  • Single brake hose built to the Standard (S) layout
  • Covers both production spells of the WR450F
  • Aeronautical braid sheath in 20 colours
  • Painted stainless steel fittings in red, green, blue, black or gold
  • Same part shared with the WR250F and YZ250FX built on the same platform

Construction and Material Quality

The hose pairs a stainless braid sheath with fittings made from stainless steel, offered painted in five colours or bare on this part. A single hose like this is a small, inexpensive thing to replace, so many owners treat the colour choice as a chance to pick something that stands out rather than matching the rest of the bike.

Shared Hardware Across the Enduro Range

Because the WR450F shares its clutch and brake master cylinders with the smaller WR250F and the motocross-oriented YZ250FX, Accossato covers all three with this one hose rather than developing a 450-specific part. The routing and length stay the same whichever of those three bikes it ends up fitted to.

Fitment and Compatibility

This hose fits the Yamaha WR450F built from 2007 to 2015 and again from 2019 to 2022. The same part also fits the Yamaha WR250F across its own production spells and the YZ250FX built from 2015 to 2021. For the WR450F's intermediate 2012–2018 model years, Accossato instead lists a separate two-hose kit under part AGF9024. Riders switching between the WR250F, WR450F and YZ250FX within a race team can treat this hose as common stock, since the same part number covers all three machines.

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. Fittings such as banjo bolts and copper sealing washers are not listed as included, so it is worth checking the connecting hardware already on the bike before starting the job.
