The seat belts are fixed to the extruded aluminium core of the C1, which acts as an all-round safety cage and protects the driver in a roll-over situation.

The BMW C1 is powered by a single cylinder 125cc, water-cooled, four stroke engine producing 15bhp at 9000rpm and 12Nm (9 lbs ft) of torque at 7000rpm.
