OEM-style chain kit for Derbi Senda.

When should you replace the chain drive ? The service life of a chain drive depends on several factors :

• Chain tension: a chain that is too loose or too tight
• Maintenance: infrequent cleaning or lubrication
• External conditions: sand, salt, mud or stones

Common signs of wear include excessive chain slack and worn front or rear sprocket teeth that appear uneven, pointed or rounded. Depending on your bike, riding style and road conditions, the chain kit may need replacing after approximately 8,000 km.

After installation, adjust the chain tension correctly and clean the chain regularly to help extend its service life.

• Rear sprocket bore: 105 mm
• Rear sprocket mounting: 3 × 2 holes
• Sprocket material: Steel

Vehicle compatibility can be difficult to confirm with certainty. Please compare the product photo and specifications above with your existing chain kit before ordering.
