A. Huret Speedometers
1. Huret-2.7 Motobecane, 2. Huret-2.7 60mm round MMI #H125F for Garelli. 3. Huret-2.0 60mm round, 4. Huret-2.7 48mm round
Good-used Huret-2.7 Motobecane speedos, unfrozen, lubed, and tested.
Long term testing: These were unfroze with acetone and re-lubricated with Tri-Flow. Then they sat on a parts shelf for four years in zip-lock bags. After that long, none had become stuck/frozen.
Huret-2.7 Motobecane speedometers: The cover is glass, so it resists scratching. Repeated exposure to sunlight fades the white background to yellow and the blue numbers to white. When the numbers are faded out the needle is still red, so speed can be estimated, like telling time on a clock with no numbers.
# price miles all are working normally unless noted
1 N/A 1780 excellent condition, works good
2 $55 5261 dark numbers, works good, but returns to 5mph not 0
3 $45 2024 barely visible numbers, works good
4 $40 7365 invisible numbers, works good
5 $35 5337 completely invisible numbers, works good
Motobecane speedo service: Accessing the needle requires removing the lower plate that hides the needle. That is done by applying pressure to the two white posts that stick through the face plate.
Good-used Huret-2.7 60 mm speedos, unfrozen, lubed, and tested.
Speed Testing: A hand drill was set to spin at a constant speed (by a stop screw in the trigger). Each speedo was spun for 30-50 seconds. The final speed was recorded.
Huret-2.7 60mm round speedometers: The test speeds all agreed quite well. These have great dampening, no jumping unless noted. The clear cover is glass, not plastic. So it does not get dull or scratched.

Huret drivers are reversible for left or right side,
because the cable can attach from either end.
The cable must rotate clockwise, viewed from above.
With the cable on, left side ones look like a d.
Right side ones look like a letter b.
The date stamp says the week 01-52 and year 75-80.
The marking says the tire outer diameter and/or the ratio.
