I am a previous owner of a 2011 1198 and loved the engine in that bike. I am looking to get back to the bike scene after about 8 years of not owning a bike. I am considering a used Ducati and leaning towards the streetfighter. Now for my question, with a little context; in considering a used streetfighter and assuming I didn't aim at the V4 model, I would likely lean towards a 1098S if I could find a decent value in price and mileage. The 1098's are several years old so I would be in the range of 5k miles and up, with some listed as high as 15-20k miles (that I have seen so far). So, given my limited experience with the L-Twin, what is a reasonable lifespan of those engines (in miles) assuming good care and valve maintenance being done at proper intervals etc.? Also, has anyone had experience in buying a higher mileage L-Twin with around 15k miles, and was it a good choice for you? Thanks in advance for any advice and shared experiences.
