DescriptionThe whole story▼
Buying a used CRF250X usually means inheriting somebody else's habits along with the bike, and the way the previous owner set chain tension is one of the things that comes along for free. Accossato's RTH1 gives the CRF250X built from 2004 to 2017 a fresh pair of rear axle blocks that follow the stock adjustment method, with no screw built into the block itself, for riders who would rather keep doing things the way the bike was designed to be set up.
Key Features
- Rear axle blocks for the Honda CRF250X, 2004 to 2017
- Accossato code RTH1, one pair, left and right
- No built-in adjusting screw; chain tension set the stock way
- Black, red or silver
- Accossato also lists a matching chain guide, GCH1, for this bike
- A version of the blocks with an adjusting screw, RCH1, is listed for the same bike
- No German ABE on file; built for off-road and competition use
Construction and Material Quality
Each RTH1 block takes the place of the original at the swingarm end, matching the stock adjustment method rather than adding a feature the bike never had. Accossato offers the pair in black, red or silver, a small enough choice that most owners pick whichever shade already suits the rest of the bike. On a used machine, a block with a rounded edge or a hairline crack is easy to miss until the wheel is out, which is exactly when a straightforward check is worth doing.
Sticking to the Stock Method on a New-to-You Bike
Some riders inherit a bike with the chain already running loose, the axle blocks worn enough that nobody can say when they were last replaced, and no record of what tension it was set to when it last felt right. Rather than guessing at a different adjustment method, fitting a fresh pair of blocks that follow the same stock process the bike was built around removes one unknown from an otherwise unfamiliar machine. The rider can then set tension to the figures in the handbook with new blocks under the axle, confident that any looseness from here on is genuinely new rather than a question mark left over from the previous owner. It is a small step, but on a bike bought without much history, ruling things out one at a time is often the fastest way to trust it.
Fitment and Compatibility
Accossato lists the RTH1 for the CRF250X built between 2004 and 2017 on its own application list, a single run specific to this bike rather than shared across several models. Checking your own frame's exact build year against that list is still worth the few minutes it takes before ordering. For this bike, Accossato also offers a matching chain guide under the code GCH1, and a version of these blocks with an adjusting screw built in, RCH1, for riders who would rather adjust tension that way instead.
Road Approval
Accossato has no German ABE on file for the RTH1, so the blocks are intended for off-road and competition use rather than for use on public roads.
Scope of Delivery
This listing covers one pair of rear axle blocks, left and right, in the colour you select.
