Setup, Compatibility & Care
To ensure proper function, keep the lock clean and free of road grime. Lubricate the SEK DISCTECH core periodically with a graphite-based lubricant to maintain smooth key operation. Avoid using oil-based lubricants, which can attract dirt and cause the locking pins to stick. Before purchasing, verify that your motorcycle's brake disc vent holes have a clearance of at least 18mm to accommodate the shackle. When not in use, the lock is small enough to store under the seat or in a tank bag. Keep your spare keys in a safe, separate location and record the key code provided with your purchase.
