The oil filter of Haojue USR125 is located inside the round cover in front of the right side cover of the engine. Below are specific details about the Haojue USR125: 1. Braking system: The USR125 adopts a front disc and rear drum brake configuration, which is relatively common among mainstream scooters. However, the USR125 uses a front dual-piston brake caliper, and the brake disc is a wave disc, which looks visually appealing. The rear drum brake has a size of 130mm, larger in diameter compared to typical rear drum brakes. 2. Tire specifications: The original equipment comes with Cheng Shin tires. The front tire specification is 90/90-12, and the rear tire is 100/90-10. The front 12-inch size is larger than the 90/90-10 size of the Jog i and Fuxi, which is more beneficial for reducing impact force.

As a long-time motorcycle rider, let me share the location of the Haojue USR125 oil filter. Generally, it's installed on the lower right side of the engine, near the bottom. You'll need to lift the seat or crouch down to see it. The position is designed for easy access to facilitate user replacement, but remember to ensure the engine is cool before inspection to avoid burns. If you can't find it, you can first check the diagram in the user manual or search for reference images online. It's recommended to replace both the oil and filter every 5,000 kilometers - doing it too frequently isn't economical. By the way, keeping the filter clean can extend engine life and reduce noise issues. I changed mine last time myself - the process was quite simple, but don't overlook safety; wear gloves to protect your hands.

I've repaired many of these scooters. The oil filter of the Haojue USR125 is installed near the lower part of the engine close to the right leg, specifically located beneath a cover plate on the side of the engine casing. You can reach out and feel a cylindrical component—that's it. When replacing it, first drain the old oil completely, then use a wrench to loosen the filter cover, being careful not to apply too much force to avoid damaging the threads. This placement is designed to make routine maintenance easier, saving you unnecessary trips to the shop. Speaking of maintenance, it's recommended to check the filter every 4,000-6,000 kilometers. A clogged filter can affect lubrication and cause engine overheating. Regular maintenance also improves fuel efficiency. Mastering these small tips can save you both hassle and money.

As a former owner of the Haojue USR125, I can confirm the oil filter is located on the lower right side of the engine, visible after removing the protective cover. In terms of design details, it features a circular shape positioned adjacent to the oil drain hole. While routine inspections can be performed independently, those with limited mechanical skills are advised to seek professional assistance. The well-considered placement minimizes oil splash contamination during maintenance. A crucial step when replacing is to run the engine for a few minutes to warm the oil before draining. Timely filter replacement is essential in maintenance - failure to do so allows contaminants to accumulate, accelerating engine wear and significantly increasing failure risks. Regular inspections not only enhance driving safety but also prove cost-effective for long-term ownership.
