KTM has a reputation for being one of the most forward-thinking motorcycle companies, but that sometimes comes at the expense of reliability, particularly in their earlier models. Their flagship naked bike, the 1390 Super Duke R, is the latest evolution of that bike, with impressive power figures and cutting-edge electronics. But potential buyers and enthusiasts worry about how high-performance machines fare with typical use. Riders are divided on whether the electrical systems or premature wear on some components is an issue or whether the bike is durable. Modern motorcycles, especially those with advanced electronic systems, are often much more complex, which in turn can increase the number of potential failures. Also, the engine and the bike as a whole will be high-strung and may have a narrower performance envelope and require more frequent maintenance or not be so forgiving of neglect compared to more conservative designs. This question is aimed at finding out in real-world experiences & opinions on the 1390 Super Duke R's reliability, taking into account build quality, how much maintenance is required, and long-term ownership costs.
