How many kilometers should the gear oil of Suzuki UU125 be changed?
2 Answers
Suzuki UU125 gear oil should be changed every 10,000 kilometers according to the manual. Here is the relevant introduction about gear oil: Function: Gear oil mainly refers to the lubricating oil for transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance. Gear oil primarily lubricates gears and bearings, prevents wear and corrosion, and helps dissipate heat from gears. Importance: Gear oil is used in gear transmission mechanisms such as automobile steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubricating gears, resisting wear, cooling, dissipating heat, preventing corrosion and rust, cleaning, and reducing gear surface impact and noise.
I've been riding a Suzuki UU125 for four years, and from personal experience, I recommend changing the gear oil every 5,000 kilometers for optimal performance. If you frequently ride in congested urban areas or often carry heavy loads, you might need to change it as early as 4,000 kilometers. Gear oil lubricates the transmission system to protect the gears from wear. If it ages or turns black, it loses its lubricating properties, and you risk damaging the transmission, which could lead to costly repairs. I check the oil level and color every six months—if it appears cloudy or sticky when dripped on paper, I replace it immediately. Doing it yourself isn’t too difficult: buy a compatible 80W-90 gear oil, loosen the drain plug to let the old oil fully drain, tighten it back up, and refill with fresh oil to the marked level. It’s simple, hassle-free, and saves on maintenance costs. Don’t skip this step—exceeding 6,000 kilometers could lead to unexpected issues.
