Here are a few reasons why:
Transmission oil is formulated for the specific needs of motorcycle transmissions. Motorcycle transmissions operate under different conditions than car engines, and they require oil that is specifically designed to withstand these conditions. Transmission oil is typically thicker than motor oil, and it contains additives that help to protect the gears and other components of the transmission.
Using motor oil in a motorcycle transmission can cause damage over time. Motor oil is not designed to withstand the high temperatures and pressures that are generated in a motorcycle transmission. This can cause the oil to break down and lose its protective properties, which can lead to premature wear and tear on the transmission.
In addition, using motor oil in a motorcycle transmission can make it difficult to shift gears. Motor oil is not as slippery as transmission oil, which can make it more difficult for the gears to engage properly. This can lead to problems with shifting gears, and it can also damage the transmission.
For all of these reasons, it is important to use motorcycle transmission oil in a CR80 instead of plain motorcycle 10W-40 motor oil.
