Why Are Motorcycle Jackets So Short?

Motorcycle jackets are short because they are cut for sitting on a bike: a waist-length jacket lets the rider move freely and does not bunch up over the thighs, while the asymmetrical zip and belt keep the wind out. The cut goes back to racing riders around 1905, who cropped their close-fitting leather jackets to the waist.

This answer is part of our guide to leather jacket styles and their history.

Short for the riding position

A long jacket works against a seated rider. Leather Collection notes that a riding jacket that is too long folds while you sit, and one that is too short rides up. A guide from Fox Creek Leather puts it this way: standing, the jacket reaches the belt line; seated, it rests on the thighs.

The Museum at FIT says the Perfecto's waist was cropped so the wearer could move freely while riding. Its buckled belt and asymmetrical zip were added to shield the rider from wind.

Riders once wore long coats

Early riders did wear long leather. From the 1890s, cold-climate riders wore thigh-length, usually double-breasted coats. Around 1905 and 1906, as racing bikes got faster, riders switched to close-fitting jackets cropped to the waist, with short collars to stop flapping.

The same shift shows in the biker jacket itself, Wikipedia notes: once worn to mid-thigh, it now usually ends at a fitted waist. Our brief history of jackets and their styles follows the wider story.

Short in front, longer at the back

A good riding jacket is not short everywhere. Protective jackets are often cut longer at the back to cover the kidneys, and fit guides look for a kidney panel over the lower back.

Racing cuts go shortest. A racer fit is very snug and shorter, with pre-curved arms, so the rider can tuck in fully.

Is your jacket too short?

Check it on the bike, not just in the mirror. Seated with your arms out to the bars, the sleeves should reach your wrists and the back should cover your lower back. Full measuring steps are in our motorcycle jacket size chart and measuring guide.
