DescriptionThe whole story▼

New tyres on a 300 EXC are usually fitted alongside a proper look at everything else near the rear wheel, since the bike is already up on a stand with the chain guard off and the back end exposed. Accossato's RCM1 covers the 300 EXC built from 2000 to 2018, a pair of rear axle blocks with their own adjusting screw, well placed to check at the same time as a tyre change.

Key Features

  • Rear axle blocks for the KTM 300 EXC, 2000 to 2018
  • Accossato code RCM1, supplied as a pair, left and right
  • Each block carries its own adjusting screw for chain tension
  • Orange, black or silver
  • Also listed for a wide run of Husqvarna four-strokes sharing this swingarm
  • Accossato's RTM1 covers the same bike without the adjusting screw
  • No German ABE on file; built for off-road and competition use

Construction and Material Quality

An adjusting screw is built into each RCM1 block, so the rear wheel can be pushed back by turning that screw rather than levering the axle into position by hand, and both blocks mount where the stock parts sat on the swingarm. The pair is offered in orange, black or silver, generally picked to match the rest of the bike's finish. Once a block has worn to the point where it no longer holds the wheel square, it is worth swapping for a fresh pair rather than compensating for it elsewhere.

One Job Leads to the Next

Pulling the rear wheel for new tyres already means loosening the axle and moving the blocks out of the way, so checking their condition at that point costs almost no extra time compared with doing it as a separate job later. Riders who treat a tyre change as a chance to look at everything in that corner of the bike, rather than just swapping the rubber and putting it back together, tend to catch worn axle blocks before they become a problem on their own. Re-setting chain tension evenly on both sides while the wheel is already loose finishes the job properly rather than leaving it for next time.

Fitment and Compatibility

For the 300 EXC, the RCM1 covers 2000 through 2018 on Accossato's own list, a wide enough bracket that the actual frame year deserves a check rather than an assumption. The same pair of blocks turns up against several Husqvarna four-strokes built on this swingarm as well. Those who would rather keep the stock method of setting chain tension can fit the RTM1 in exactly the same position instead.

Road Approval

No German ABE is on file for the RCM1, so Accossato lists it for off-road and competition use rather than for use on public roads.
