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'll have to assemble them carefully as it appears to be a soft metal and can easily be crossed if you're 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.
