There is some loss to a CVT vs gear driven. Smaller child size dirt bikes and ATVs come with 3 or 4 speed transmissions. Check out a Yamaha Zuma50FX with 12:1 compression ratio or a 125cc Honda Grom. Engine compression ratio and aero drag reduction may give the biggest efficiency gains. MotoIQ.com does a Honda Ruckus project to get highway speed.
