The answer to this question is difficult to determine definitively as there are a number of factors that can affect the cc (cubic capacity) of a bike. However, we can look at some of the largest bikes on the market and make an educated guess as to which one has the highest cc.
Some of the biggest bikes on the market include motorcycles like the Honda Goldwing 1800cc, Suzuki Hayabusa 1300cc, and Kawasaki Ninja ZX-14 1200cc. All of these bikes have massive engines and are capable of high speeds and impressive acceleration.
So, which one of these bikes has the highest cc? It is likely that it is either the Honda Goldwing or Suzuki Hayabusa, as they both have very large engines. However, without more information it is difficult to say for sure.
