🏍️All-wheel drive motorcycles, like the Rokon, offer better traction and are suited for off-road adventures.
🚲Grip shifts, like those found on Vespas, offer a unique way to control the clutch and shifter by twisting the whole mechanism on the grip.
🔧Front suspension innovations, such as girder-style suspension, have not been widely adopted due to design challenges and brand image.
🚗Motorcycle-car hybrids, like those with roofs, have not gained popularity due to the preference for traditional-looking motorcycles and the inherent freedom of motorcycles.
🛵Linked brakes, which combine the front and rear brakes with a single pedal or lever, have been abandoned in favor of separate brake controls for better handling and safety.
