Universal Parts #25H Heavy-Duty Drive Chain - 47 Links
Description
This Universal Parts #25H heavy-duty drive chain is a reinforced replacement for getting a compatible chain-driven scooter or pocket bike back into action. Heavy-duty steel plates and pins provide increased tensile strength and wear resistance compared with a standard #25 chain, while the pre-sized 47-link length makes replacement straightforward when it matches your existing setup, including popular models such as Razor E200, E300, and Pocket Mod.
Key Features
- Heavy-duty construction: Reinforced steel plates and pins improve durability and resistance to stretching compared with standard #25 chain.
- Pre-sized replacement: 47-link length for drive systems requiring this exact chain configuration.
- Consistent engagement: 1/4-inch (6.35 mm) pitch matches compatible #25H sprockets.
- Smooth power transfer: Reduced-friction design supports efficient, quieter operation.
- Gas and electric applications: Suitable for matching small chain-drive systems, including scooter, pocket-bike and custom builds.
