There are some brands of bicycles that can cost more than the down payment on a car. Why? Surely making a bike lightweight and reliable isn’t so difficult that it warrants that price? Is it just the brand name or maybe it has to do with customization options?
Superbike championships use road bikes with a change of fairings and upgrades to things like exhaust, brakes, and suspension.
Hell, Isle Of Man TT lightweight class has used stuff like the ER6f as a base which is a budget commuter bike, lol
A halo model super sport is basically a street legal race bike.
