DescriptionThe whole story▼

Owners who have ridden a 500 EXC-F for years sometimes end up sticking with whatever came off the bike first, simply because nothing has ever given them reason to look at an alternative, and the stock style of axle block tends to be one of those parts nobody questions until it visibly wears out. Accossato's RTM1 replaces that pair on the 500 EXC-F built between 2000 and 2018, following the same stock method of chain adjustment rather than adding a screw.

Key Features

  • Rear axle blocks for the KTM 500 EXC-F, 2000 to 2018
  • Accossato code RTM1, one pair, left and right
  • Chain tension set the stock way, with no built-in adjusting screw
  • Orange, black or silver
  • Also listed for a wide run of Husqvarna four-strokes on this swingarm
  • Accossato's RCM1 covers the same bike with an adjusting screw, for riders who prefer that method
  • No German ABE on file; built for off-road and competition use

Construction and Material Quality

The RTM1 pair takes the stock blocks' place on the swingarm without changing how tension has always been set, leaving that job to the usual nut and reference marks. Orange, black or silver are the finishes available, usually matched to the bike's existing colours. A block cracked or worn unevenly after years of use is worth a straight swap for a fresh pair.

Never Having a Reason to Change It

A part that has simply never caused a problem rarely gets a second thought, and for many 500 EXC-F owners the stock-style axle block falls into exactly that category, outlasting several chains and sprockets before it finally shows enough wear to need attention. The RTM1 is there for that moment, a straightforward replacement rather than a prompt to reconsider how the bike is set up. Swapping a worn block for the RTM1 changes nothing about the rest of the bike's routine.

Fitment and Compatibility

The RTM1 and the RCM1 carry the same application window for this bike, both covering the 500 EXC-F from 2000 to 2018. A number of Husqvarna four-strokes built on the same swingarm take the identical block. Confirming the exact frame year against Accossato's list remains worth doing given how long this window runs.

Road Approval

Accossato lists no German ABE for the RTM1, so the blocks are intended for off-road and competition use rather than for use on public roads.

Scope of Delivery

Supplied as one pair of rear axle blocks, left and right, in the colour you choose.
