The 101 Octane Odometer Transmission (MPN: 731.09.31) is designed for motorcycle enthusiasts and mechanics looking for a reliable replacement part to restore accurate speedometer readings. This component serves as the critical link between your wheel rotation and the speedometer cable, ensuring precise speed and distance tracking. While it offers excellent stability through its lateral screw design, potential users should confirm the specific gear ratio and compatibility with their exact motorbike model before installation to ensure perfect synchronization.

You will need basic hand tools such as a screwdriver or wrench to remove the front wheel and tighten the lateral screw.
It is recommended to apply a small amount of high-quality chassis grease to the gear teeth during installation for optimal longevity.
The lateral screw ensures the transmission housing stays fixed in place, preventing the unit from spinning with the wheel which would break the cable.
It is best practice to inspect the unit whenever you perform tire changes or front brake maintenance.
Check if the slotted drive is properly engaged with the wheel hub tabs and inspect the speedometer cable for kinks or internal breakage.
Verify that the lateral screw is tightened correctly and that there are no missing washers or spacers required by your specific wheel hub design.
Remove the transmission to check for misalignment or debris lodged between the gear and the hub; ensure the unit is adequately lubricated.
To install the unit, ensure the motorbike is on a stable stand. Remove the front wheel as per your manual's guidelines, detach the old transmission, and clear any debris from the wheel hub. Slide the new 101 Octane unit into place, ensuring the slotted drive aligns correctly with the hub tabs, and tighten the lateral screw to spec to prevent movement. For long-term care, occasionally inspect the unit for dirt accumulation and ensure the grease inside is not contaminated. If the speedometer cable feels sluggish, it is recommended to lubricate the inner cable while the transmission is exposed to prevent excessive strain on the new transmission gear.
