DescriptionThe whole story▼

A YZ250 kept mostly for casual weekend trail riding, rather than racing, rarely needs chain tension adjusted often enough for an owner to value an adjusting screw over the stock method they already know. Accossato's RTY1 suits exactly that kind of use, replacing the rear axle blocks on the YZ250 built between 2009 and 2018 without a built-in screw.

Key Features

  • Rear axle blocks for the Yamaha YZ250, 2009 to 2018
  • Accossato code RTY1, one pair, left and right
  • Chain tension set the stock way, with no built-in adjusting screw
  • Blue, black or silver
  • Same pair also listed for the Yamaha YZ125
  • Accossato's RCY1 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 RTY1 pair sits in the same position as the stock blocks, leaving chain tension to the usual nut and marks on the swingarm. Blue, black or silver cover the finishes on offer, usually matched to the rest of the bike. A block that has taken a hard knock and no longer sits true along its edge is worth replacing rather than left to wear further.

A Bike Ridden for Fun Rather Than Points

Not every YZ250 spends its life chasing a championship, and plenty are ridden purely for the enjoyment of a weekend trail loop with friends, with chain adjustment happening only occasionally rather than before every single outing. For a bike used this way, the stock method of setting tension is rarely a limitation, and the RTY1 keeps that approach going without introducing a feature built for a more demanding racing schedule. It replaces a worn block with one that works exactly the way the bike always has.

Fitment and Compatibility

The RTY1 shares its application window with the RCY1 on this bike, both covering the YZ250 from 2009 to 2018. The identical block is also listed for the Yamaha YZ125. Confirming the exact frame year against Accossato's list is still worth doing before ordering.

Road Approval

Accossato lists no German ABE for the RTY1, so the blocks are intended for off-road and competition use rather than for use on public roads.
