A motorcycle is stolen quickly and easily — often lifted into a van. An anti-theft lock won't stop a determined thief, but it increases time, noise, and risk, which discourages them. And insurance often requires a certified lock. Here's how to choose.
Types and Their Role
| Type | Role | Limitation |
|---|---|---|
| Disc lock | Quick deterrent, secondary anti-theft | Doesn't prevent lifting the bike |
| Motorcycle U-lock | Good level, attaches to fixed point | Heavy |
| High-security chain | Attaches to sealed fixed point | Very heavy |
| Alarm | Audible deterrent | Complement, not a barrier |
A disc lock alone blocks the wheel but the bike can be carried: it's a complement, not complete protection.
The Certification That Matters (and Insurance)
In France, the SRA level is the reference required by insurers; internationally, look for Sold Secure (Gold/Diamond) or ART (3-4 stars). Without a lock of the required level, insurance may refuse coverage in case of theft — check your policy before buying.
