In most cases, using premium fuel in a 125cc motorcycle is not necessary.
The fuel requirement of a motorcycle is usually specified by the manufacturer. Most 125cc motorcycles are designed to run on regular unleaded gasoline with an octane rating typically found at regular gas stations. Premium fuel, which typically has a higher octane rating, is formulated to meet the needs of high-performance engines or those with higher compression ratios.
Using premium fuel in a motorcycle that doesn't require it won't provide any significant benefits in terms of performance or fuel efficiency. The engine is designed to operate efficiently on regular fuel, and using premium fuel may not offer any noticeable advantages.
