KTM motorcycles, especially older models like the 990 SMT, have a largely unwarranted reputation of being high-maintenance motorcycles compared to their Japanese rivals. While there are some riders that swear by their reliability when they are taken care of, others tell horror stories of constant issues and expensive repairs.

But supporters say, with the right know-how and commitment, home mechanics can keep these bikes in good working order. Today I want to talk about the realities of having a 990 SMT at home—is it worth it for the DIY enthusiast or a frustrating money pit?
