Naked moderne.

Mid-tier modern nakeds are the most-rented, most-recommended, most-bought class of bike on the planet. Yamaha MT-09, Kawasaki Z900, Suzuki GSX-S1000, Triumph Street Triple, KTM 890 Duke, Honda CB1000 Hornet — bikes that do everything well and nothing badly.

This is the segment people upgrade into after their A2 restriction lifts, and it's also where most riders settle for life. 100–140 bhp, around 200 kg, upright, sharp handling, fits anywhere. There's a reason these bikes dominate sales charts — they're the answer to 'what should my one bike be?'
