DescriptionThe whole story▼

A hillclimb test on a CRF450X puts the rear wheel through loose, rocky ground at exactly the angle where anything that has worked loose on the bike tends to show it, and the chain running past the sprocket is no exception. Accossato lists the GCH1 chain guide for the CRF450X built between 2007 and 2016, fitted ahead of the sprocket to keep the chain tracking on line as the bike claws its way up ground like that.

Key Features

  • Chain guide for the Honda CRF450X, 2007 to 2016
  • Accossato code GCH1, mounted ahead of the rear sprocket
  • Keeps the chain running on a steady line over loose, rocky ground
  • Black or red
  • Same part also listed for the Honda CRF250R, CRF250X and CRF450R
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Accossato shapes the GCH1 to sit ahead of the CRF450X's own sprocket, in the position this swingarm calls for rather than a generic shape adapted to fit. Black and red cover the choice of finish, picked to suit the rest of the bike. A guide that has taken a solid knock from a rock on a steep climb and no longer sits flush is worth checking closely and swapping if needed, the same as any wear part exposed to that kind of ground.

A Rocky Hillclimb

Climbing a loose, rocky slope asks a lot of a CRF450X all at once: the rear wheel is spinning hard for traction while loose stone is being thrown backward and upward by the tyre, much of it heading toward the sprocket and the chain running over it. Unlike flat, loose ground where debris mostly settles, a steep climb keeps throwing material at the same spot for as long as the climb lasts, which is exactly the kind of sustained exposure a chain guide is built to take instead of the chain itself. Riders who ride this kind of terrain regularly often check the guide straight after a hillclimb session, while the climb is still fresh in mind, rather than waiting for a scheduled service to notice a problem that started there.

Fitment and Compatibility

Accossato's application list for the GCH1 covers the CRF450X across 2007 to 2016, a span worth checking against your own frame's build year before ordering. The CRF250R, the CRF250X and the CRF450R all take the identical guide, useful to know for a garage running more than one of these Hondas. Accossato's separate listing for rear axle blocks on this bike, with the adjusting screw built in or left to the stock method, covers the other wear point at the opposite end of the swingarm.

Road Approval

Accossato lists no German ABE for the GCH1, so the part is intended for off-road and competition use rather than for use on public roads.
