If the bike is 25cc then it probably does in excess of 100 mpg so the answer would be 1/100th of a gallon.
If the bike is a two litre monster like the Triumph then probably around 1/35th of a gallon.
Without knowing the size of the motorcycle you cant answer this question.
It depend on friction and other forces against motion
A million millimeters.

1km is 1,000 meters.
1km = 1000m 1km > 50m 1km is bigger
1km = 1000m520m/1km:= 520/1000 or 13/25 of 1km
1km
100000cm = 1km 50cm = 1km/1000000cm/1km 0.00005km = 50cm 50cm < 1km
1km = 1000000mm
1km -450 = -449
There is 1000m in 1km, therefore the fraction is 1000/50 which can be simplified to 100/5 which can be simplified to 20/1. So 50m is one 20th of 1km. So you need to run 20 times further to make the 1k fatty! lol
