Motorcycle Myths Debunked: Common False ‘Facts’
Motorcycle myths debunked: octane equals power, break-in myths, ABS magic, preload, exhaust HP, tire pressure, car oil, and earplug fears.
1) Higher octane = more power
Usually not on a stock map. Octane is knock resistance: Motorcycle Fuel Octane: RON 91 vs 95 vs 98
2) Never touch the throttle in break-in
Overly gentle constant load can also be wrong. Vary load inside manual limits: New Motorcycle Break-In Guide: First Kilometers Done Right
3) ABS fixes everything
ABS manages lockup; physics and tires still set limits: What Is ABS? Motorcycle Anti-lock Braking Explained
4) Preload = stiffer spring
Preload sets ride height, not magic spring rate: Motorcycle Suspension Preload: Sag, Springs, Passenger
5) Loud exhaust = free horsepower
Sound ≠ power. You may need fueling / a map: Motorcycle Aftermarket Exhaust: Sound, Power, Legal, ECU
6) Drop tire pressure when hot
Set cold sticker pressures; dumping air ‘because hot’ risks sidewalls: Motorcycle Tire Pressure Chart: PSI / Bar Guide
7) Car oil is fine in bikes

8) Earplugs hide sirens
Filtered plugs usually pass alerts while cutting wind: Motorcycle Earplugs: Wind Noise and Hearing
