Use as additional security also whenever the bike is chained. Can also be used with a chain.

Customers have found this disc lock to be strong, sturdy, and excellent value for money. It's considered equally effective as more expensive models and praised for its solid construction. While the lock fits easily onto various motorcycle discs and sprockets, inserting the key can be fiddly for some. Its portability is appreciated, fitting into pockets or under seats, and its visibility adds a deterrent factor. Customers highlight the extra features like reminder leads and belt pouches, making it overall highly recommended.
