Although great performance gains are often claimed, the theory of speedholes remains unproven. However, if one would like to be so dumb as to do so, good luck.
"I swear my moped goes, like, 2 mph faster than it did before!!!" -Dave B.
"The holes will make the air flow through the bike thus reducing air pressure and allowing the bike to be more aerodynamic. That then makes the bike go faster. It really works!" -Dan WK
"Zese are speed holes, Zey make Ze car go faster" -Shady Car Salesman
