I apologize for the confusion, but it seems there is an incorrect statement in your question. Royal Enfield Bullet motorcycles do have gears like most other motorcycles. Gears are an essential component of the transmission system in motorcycles and allow riders to vary the power and torque output of the engine to suit different riding conditions.
Royal Enfield Bullet motorcycles typically have a 5-speed or 6-speed transmission, depending on the model. The gear shifting mechanism allows riders to shift up or down through the gears to match the speed and load requirements. This enables better acceleration, higher top speeds, and efficient power delivery.
It's worth noting that Royal Enfield motorcycles are known for their traditional, classic design, and they often embody a retro aesthetic. This design philosophy may give them a distinct appearance compared to some other motorcycles, but they still incorporate modern features like gears to ensure optimal performance and versatility on the road.
