- Chain Alignment: Ensure the chain is perfectly aligned between the front and rear sprockets. Misalignment causes uneven wear and reduces component lifespan.
- Период провале: A short break-in period (approximately 100-200 miles) is recommended for new sprockets and chains. Avoid aggressive acceleration and deceleration during this time.

- Examine the chain for tight spots, rust, or excessive slack.
- Perform these checks every 500-1000 miles or as recommended by your vehicle's service manual.
Чишћење и подмазивање
- Clean the sprocket and chain regularly using a suitable chain cleaner to remove dirt, grime, and old lubricant.
