Hi
A tach is an vitally important gauge for a scoot
I do use mine alot while riding and try to keep my rpms way under there maximum when riding also imho they are vital when your modding parts for better perfomance to make sure you stay with in your powerband
On scoots that didnt come with a tach i install one of these

Take care and ride safely
Yours Hank
