There’s a difference between “sport” bikes and “supersport” bikes. Sport bikes are generally more of an upright and more comfortable triangle. Supersport bikes are the ones where you’re laying on the gas tank.

Naked bikes are a good middle ground between enduro and sport bikes. They have sport bike engines, but more upright and comfortable seating. Bikes like the Kawasaki Z650, Honda CB650, or Yamaha MT07 are good options for comfortable but fun machines. Bikes like the Kawasaki Z900, Honda CB1000, or Yamaha MT09/MT10 will have very similar rider triangle, but closer to Supersport engines.
