Reinforced O-Ring Chain Kit for Honda XLR 125 R-W, X, Y, 1, 2 1998–2002
This reinforced O-ring chain kit for the Honda XLR 125 R from 1998 to 2002 is designed as a complete secondary drive set. It includes a front sprocket with 17 teeth, a rear sprocket with 51 teeth, a reinforced O-ring motorcycle chain and a matching chain connecting link.
The chain kit is suitable for the model variants Honda XLR 125 R-W, XLR 125 R-X, XLR 125 R-Y, XLR 125 R-1 and XLR 125 R-2. Replacing the front sprocket, rear sprocket and chain together allows the main wear components of the final drive to be renewed at the same time.
17 Teeth Front and 51 Teeth Rear
The front sprocket has 17 teeth, while the rear sprocket has 51 teeth. This combination represents the specified gearing of the chain kit. Before ordering, the currently installed sprocket sizes should be checked, especially if the motorcycle has previously been modified or fitted with a different gearing setup.
-
17-tooth front sprocket: part of the complete secondary drive system.
-
51-tooth rear sprocket: matched to the stated gearing configuration.
-
Reinforced O-ring chain: designed for motorcycle final drive applications.
-
Chain connecting link included: supplied as part of the complete chain kit.
-
Complete set: front sprocket, rear sprocket and chain are replaced together.
Why Replace the Complete Chain Kit Together?
The chain, front sprocket and rear sprocket work directly together. As mileage increases, not only the chain but also the tooth profiles of both sprockets wear. Replacing only one component means the new part will continue to run against already worn mating surfaces.
Replacing all three components together provides a uniform starting point for the complete secondary drive. This is particularly useful if the chain has uneven elongation, requires frequent adjustment or the sprocket teeth already show visible wear.
Reinforced O-Ring Chain for the Honda XLR 125 R
The included reinforced O-ring motorcycle chain uses sealing rings between the inner and outer chain plates. These O-rings help retain lubricant around the chain pins while reducing the entry of dirt and contamination.
On an enduro motorcycle such as the Honda XLR 125 R, the chain drive can be exposed to dust, dirt, rain and changing riding conditions. A properly maintained O-ring chain supports smoother operation and reduces maintenance requirements compared with a non-sealed standard chain.
Suitable for Enduro Use and Everyday Riding
The Honda XLR 125 R can be used both for everyday riding and on unpaved roads. Repeated load changes and changing surface conditions place regular stress on the chain drive. A correctly matched chain kit is therefore important for consistent power transfer from the gearbox to the rear wheel.
If the chain tension varies when the rear wheel is rotated, if the chain has excessive play or if the sprocket teeth appear pointed or hooked, the condition of the complete chain set should be inspected.

Precisely Manufactured Sprocket Components
The front and rear sprockets are designed for smooth chain engagement. Accurate tooth geometry supports consistent running and helps reduce unnecessary load peaks within the drivetrain.
On an older motorcycle such as the Honda XLR 125 R, the sprocket carrier, front sprocket mounting area and adjacent components should also be checked for unusual play or visible damage during replacement.
What to Check if Chain Wear Is Excessive
If the chain quickly becomes loose again after adjustment, individual chain links become stiff or the motorcycle produces noticeable drivetrain jerking during load changes, advanced wear may be present. In this case, the chain, front sprocket and rear sprocket should be checked together.
A complete chain kit allows all directly interacting drive components to be replaced at the same time.
Important Maintenance Points
-
Check chain tension: the specified chain slack should be inspected regularly.
-
Clean and lubricate the chain: especially after riding in rain, dust or mud.
-
Inspect sprocket tooth profiles: pointed or hooked teeth can indicate advanced wear.
-
Check chain slack at several points: varying tension may indicate uneven chain elongation.
-
Inspect both sprockets together: all components influence the running behaviour of the chain.
