3 Answers
Suzuki UU125 scooter's transmission case screw size is 8mm. Here is some relevant information about the Suzuki UU125: Appearance: The new model's appearance is more angular compared to the UU125i, with more fold lines and geometric-shaped outer coverings replacing the previously gentle and soft 'little sheep' look, reflecting a sporty feel. The currently popular V-shaped front face makes the two headlights look less cute and more stylish. The headlights use halogen light sources, but with sufficient power, the lighting effect is not bad. Overview: In terms of configuration, it features front upright shock absorbers and rear single-sided independent shock absorbers. For braking, the base model comes with front and rear drum brakes, while the high-end version has a front disc brake and rear drum brake. In terms of power, like the YY125i, it has a maximum power of 6.9kW and a peak torque of 9.8N.m.
As a long-time motorcycle repair technician, I recall that the transmission case screws for the Suzuki UU125 are typically M6×1.0—6mm in diameter, 1.0mm pitch, and approximately 15mm in length. However, specifics may vary depending on the model year and production batch. It's best to consult the original service manual or contact an authorized 4S dealership for confirmation, as they maintain detailed databases. Precision in sizing is critical: overly loose screws may cause oil leaks or abnormal noises, while overtightening risks damaging the case threads. During repairs, I routinely use a torque wrench set to 35Nm and recommend stainless steel screws for rust resistance and durability. Transmission maintenance is vital—regularly inspecting screws and oil seals can prevent major overhauls. If unfamiliar with tools, avoid forceful disassembly to prevent stripped threads and malfunctions; opting for a professional shop ensures both convenience and safety. The modest repair cost ultimately safeguards your vehicle's longevity.
Having ridden motorcycles for so many years, I've used the UU125 quite a bit. The transmission case screws are usually M6 size with a pitch of 1.0mm and a length between 15-20mm. When buying parts, just choose the original factory specifications. During maintenance, I usually measure the old screws with calipers to confirm, or search online for matching products. Replacing them yourself is simple: clean off any dust before loosening the case cover screws, apply a bit of lubricant to the new screws to prevent rust, and slowly tighten them with a socket wrench until they feel secure. Don't over-tighten; if the size isn't right, transmission efficiency will drop, causing vibrations or noise, which affects the riding experience. I recommend checking them every six months, along with changing the transmission oil, to ensure overall performance remains stable.
