Bought these to fit the stock headlight and bracket on my 2003 SV650. I used mounting rings, not levers. It fits perfectly on the OEM mounting bracket and locks everything in place. You must assemble them carefully as they look like soft metal and can easily be cut if you are not careful. Do not apply excessive torque to the bolts, approximately 8 to 10 ft-lbs. Anyway, it doesn't take much to hold up. Once assembled, it looks like a factory installation.
