DescriptionThe whole story▼
A deep sand track throws a different kind of debris at a CRF450R than a hard-packed one, flinging fine grit upward in a steady spray rather than the odd sharp stone, and the rear sprocket sits right in the path of it on every lap. Accossato lists the GCH1 chain guide for the CRF450R built from 2007 to 2015, a guide fitted ahead of the sprocket to keep the chain on line through exactly that kind of track.
Key Features
- Chain guide for the Honda CRF450R, 2007 to 2015
- Accossato code GCH1, mounted ahead of the rear sprocket
- Keeps the chain tracking on line through sand, grit and loose going
- Black or red
- Same part also listed for the Honda CRF250R, CRF250X and CRF450X
- Accossato also lists rear axle blocks with or without an adjusting screw for this bike
- No German ABE on file; built for off-road and competition riding
Construction and Material Quality
Accossato shapes the GCH1 to the CRF450R's own sprocket position, so the guide sits exactly where this swingarm needs it rather than being a shape adapted from somewhere else. Black and red are the two finishes on offer, picked mainly to suit the rest of the bike rather than for any difference underneath. A guide caked in sand after every lap is worth a proper look between motos, since a steady spray of grit works at a surface over a full race in a way a single hard hit does not.
Protecting the Sprocket in Deep Sand
Riding a sand track for a full moto means the rear wheel is almost never running clean; it is throwing a fine spray up off the surface with every lap, and some of that spray is heading straight for the sprocket and the chain wrapped around it. A chain guide fitted ahead of the sprocket gives that spray somewhere to land other than between the chain and the teeth it is meshing with, which matters more here than on firmer ground simply because there is so much more loose material in the air for an entire session. Riders who race mostly on sand tracks tend to notice wear on this part sooner than riders on hard-pack, and checking it between motos rather than only at the end of the day catches a problem while there is still time to do something about it before the next start.
Fitment and Compatibility
The CRF450R sits on Accossato's application list for this guide across 2007 to 2015, a window worth checking against your own bike's build year before placing an order. Three other Hondas take the identical part: the CRF250R, the CRF250X and the CRF450X, so a rider with more than one of these in the garage is not buying a different guide for each. Rear axle blocks for this same bike come with or without a built-in adjusting screw depending on which method of setting tension is preferred, and either style can be added to the same order as the guide.
Road Approval
No German ABE is on file for the GCH1, so Accossato lists it for off-road and competition use rather than for use on public roads.
