Yamaha Motor (Yamaha) Bike Lock TOUGH LOCK YL-01 Chain + Padlock 2.5m Blue Q5K-YSK-107-T01 Purchased in 2019 and used outdoors. The blue cover deteriorated and became tattered over time, so I removed it. Although there is a lot of rust overall and it is not in a clean condition, the chain lock function works without any problems. I have been using it until today, and the key cylinder is also smooth. I decided to list it for sale because I need to dispose of it due to the sale of my motorcycle. This is a very sturdy type of Yamaha chain lock, so I think it will be difficult to cut or break. Because it is a long type, you can flexibly consider security, such as locking multiple motorcycles together or using a ground lock. A web search reveals that the cover deterioration of this product is a common issue, and some people have made their own covers. If you think you can make good use of it, please consider it. Three keys are included. Weight is approximately 7kg. ※ The following is from the manufacturer's product description ■ Features TOUGH LOCK logo print Longest class length Extra-thick long chain + padlock Reflective sleeve for great appeal in the dark Uses a wave key with excellent operability and stability ■ Specifications Padlock: φ11 shackle, hardened silver processing, pin cylinder lock for wave key Chain: Thickness 12mm4 square, length 2.5m, hardened silver processing, figure-eight ring at one end Included ring: 12mmφ80 (figure-eight hanging possible) Sleeve: Blue, with reflective lines (2 lines on one side) #ChainLock #BikeLock #GroundLock #KITACO #Yamaha
