Overview
The Lucas Oil Synthetic SAE 75W-140 V-Twin Gear Oil, part number LUC10791, is a synthetic gear oil blended with synthetic base oils and a synthetic additive package. It is designed for V-Twin motorcycle transmissions and suits heavy duty or high performance transmissions.
It is designed to run cool and quiet with reduced wear and drag, and to hold up under high horsepower and high temperatures. It is universal fit, so it is not tied to a particular motorcycle model.

- Blended with synthetic base oils and a synthetic additive package
- Designed especially for V-Twin transmissions
- Designed to run cool and quiet, with minimum wear and minimum drag
- Stands up to high horsepower and high temperatures
- Suited to heavy duty or high performance transmissions
Gear oil care in V-Twin transmissions
A motorcycle transmission often shares its oil with the clutch or runs in a compact housing, so the gear oil works hard in a small volume. Gear teeth and shafts depend on a stable film, and heat and shear gradually thin the fluid. Checking the level and condition at regular intervals shows whether the oil is still doing its job, and a fluid that has turned dark or gritty is a sign it is time for a change.
When draining, look at the magnetic drain plug. A small amount of fine metal is normal, but larger flakes or a heavy coating can indicate gear or bearing wear. Avoid mixing different gear oils in the same housing, and fill to the level set for your transmission rather than estimating.
- Check fluid level with the bike level and the transmission cool
- Inspect the drain plug magnet at every change
- Replace the fluid if it looks dark or gritty
- Clean the fill and drain plug threads before reinstalling
