The frequency of chain lubrication for the KTM Duke 200, or any motorcycle for that matter, can vary depending on several factors such as riding conditions, weather, and personal preference. However, as a general guideline, it is recommended to lubricate the chain of a motorcycle every 500 to 800 kilometers (300 to 500 miles).
Regular chain lubrication is important to maintain the performance and longevity of the chain and sprocket system. Lubricating the chain helps reduce friction, prevent rust and corrosion, and prolong the life of the chain. It is also essential to use a high-quality chain lubricant specifically designed for motorcycle chains.
It's worth noting that if you frequently ride in harsh or dusty environments, you may need to lubricate the chain more frequently. Additionally, it's a good practice to inspect the chain regularly for signs of wear, tension, and proper alignment.
Please keep in mind that the recommended maintenance intervals and procedures can vary slightly depending on the specific model year of the KTM Duke 200. For the most accurate and up-to-date information, I recommend referring to the owner's manual of your motorcycle or contacting a KTM dealership for specific guidelines regarding chain lubrication.
