No. Just buy a bike with EFI if you don't want a carburetor. But these are single cylinder engines, and the carbs are easy to jet and tune. Also, you should know that you are stuck with the factory EFI "tune" when you buy an EFI model. It automatically adjusts for temperature, altitude. but it does so based on EPA compliance (LEAN).
The real benefit of old school carburation is control. You can make any modest changes you see fit to maximize throttle response, minimize back firing and lean firing conditions that are not the best for engine life.
And you save hundreds of dollars! Maybe thousands!
Bottom line is carburetors work and allow more nuanced adjustment if you are so inclined. You are 100% in control.
I should also mention that EFI means that you have more sensors (oxygen and temperature), and a fuel pump, and an EFI control module. Any glitches in these sensors, or the EFI system will require diagnosis. EFI fans may claim that these issues rarely happen. While it is true that EFI is pretty reliable, it can be confusing to diagnose failures. Once properly jetted, carburetor maintenance usually just involves cleaning. Low tech has its advantages!
