Markings: The brass end caps on VDO speedo drivers are marked with the tire or rim that they are geared for. 1970’s metal drivers are marked with the tire outer diameter (23, 22, 21, 20). 1980’s plastic drivers are marked with the rim size (19, 18, 17, 16). The tire OD’s are 4 inches more than the rim sizes, because moped tires are about 2 inches tall.
Batch marking: The marking that looks like a gear ratio is not. It’s some kind of batch number.
Tire marking: On some (21LH 6/61 and 23LH 23/5) the tire size marking disagrees with the measured gear ratio.
Side: Most (10 of 14) VDO speedo drivers are for the left side. Some (2 of 14) are for right side. Some (2 of 14) are for left or right side. On those the cable can attach in two places with opposite rotation.

Greasing: The 70’s metal VDO speedo drivers had a grease zerk, but the 80’s plastic ones did not. One way to grease them without a grease gun or zerk is with spray chain lube. It penetrates in thin and then soon becomes thick. Another way is with a 5cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel).

Derbi 1.8/1.8 cables: Many Derbi speedometer cables have a kink below the speedometer that causes the inner wire to break repeatedly. The kink is from the back of the “pancake” headlight pushing the speedo cable back. There is no easy remedy. As with any speedometer cable, any kink or sudden change in direction will eventually cause the inner cable wire to break there, because as it rotates it is being bent back and forth.
