Best sprocket combination for street riding

Not long enough. Go 20/35. Why not race some Bugatti SS Veyrons . Trust me I know. All kidding aside I was running 19/38 on my turbo bike and it was too long for street. Couldn't get out of 4th unless I wanted to putt around like some slow ass 1000+lbs Harley with an 88ci
can't get a 35 to fit a OEM rear carrier or I would have one
