I know this is an old thread I'm reading. What Honda did was a gift not adding a 6th to the trans inherited from the ST. Ask me how I know why a 100hp bike with 6th gear will be getting you in trouble. it's just the way most people ride up to the speed the bike starts to hum a little so another gear means cruising too fast.Back in the 80s, I owned a V65 Sabre. 121 hp, hydraulic clutch, 6 speed motorcycle. Now that was a bike that hauled a$$.
