We've researched the purpose of a hump in a motorcycle suit to determine the primary benefits for riders.

The hump in a motorcycle suit is beneficial to the rider for both safety and performance because it:

The Hump as an Aerodynamic Element

It’s no secret that aerodynamic drag determines the winners and losers of speed racing by almost 90%. Drag is a force that tries to prevent the quick movement of a bike through the air. This force is created due to the pressure difference between the rear and the front of the bike.

So, with the hump occupying the space between your helmet and your suit, air flows smoothly over your suit to reduce turbulence. Turbulence leads to aerodynamic resistance, which then leads to loss of the much-needed maximum velocity. Simply put, it reduces the speed of your bike. Apart from enhanced airflow, your tucked position, coupled with an integrated helmet, benefits greatly from the aerodynamics provided by the hump. Once this is in place, you won’t struggle to keep your entire body and head in position while racing.

The Hump as a Store for Hydrating Fluids

As the design progressed, the hump found more uses, including to house a hydration bag. The hump's interior has witnessed major modifications to incorporate a camel bag, which is expertly connected to the helmet using a built-in hydration system. The rider can directly drink while on track.

Whether you’re an amateur or professional rider, your body needs constant hydration to give it energy, keep it alert, and increase motivation. You will find hydrating is mandatory, especially when participating in races hosted in hot climates. A convenient hydration store with an accessible, no-hands nozzle means you don’t struggle to quench that thirst. 

The Hump as a Store for safety LEDs and electronic gadgets

In addition to hydration storage, humps in motorcycle suits also provide essential storage areas for safety lights and electronics. For instance, the Mugello R motorbike suit has been designed to incorporate a safety LED that blinks upon the rider’s fall. This blinking light makes the victim visible to other riders to avoid injuring the victim more, especially during low-light and dark conditions. Important gadgets such as the USB chargers and noise-canceling earplugs can also be housed in the hump.

If there’s one thing you should consider when purchasing the race suit, then it’s comfort. Your motorbike race suit should snugly fit you, without being loose or too tight. Motorbike race suits come with extra inside padding that works optimally if close to the body. This is ideal for protecting your shoulders, elbows, and the back.

Check that the suit fits you comfortably in the riding position, not the standing position. This is because a comfortable suit in the standing position may be too loose or too tight in the riding position. To be precise, make sure that the motorbike suit:

  • Can breathe properly
  • Can retain circulation in your extremities (without tingling in the hands or feet)
  • Does not restrict movement to get on and off the bike
