I have tried fork mount and that was a pain as our forks are so wide you have to bend the cafe style brackets and in my opinion that looks a bit shite. Hard to find a nice looking headlight that is 7" plus to combat this.
I have also tried the bates style headlights and as part of vehicle testing (once a year here) they can be a pain as they don't stay perfectly vertical and that leaves you open to a fail on your test.
Fork mounted can also have this issue in my experience.
The original Savage design is actually a good one, with its set and forget adjustment and I think it looks pretty cool. Only issue for me is the plastic bucket - mine has cracked already after 8k.
So to the point: this week I bought a Intruder 1400 to try that solution. The Intruder is the same size lens (5.5") but has a solid steel bucket. The Intruder headlight I ended up getting had stripped screws and is a bit rusty but luckily the Savage front lens unit will also fit in the Intruder bucket. Just. Tight fit and I might open the bucket holes a touch with a dremel, but it works.
Main issue is the bottom mounting holes. Intruder are a bit wider (40mm). I will probably weld a plate at the bottom and redrill.
Anyway a solution but not a perfect one. If I went this way again I would just try to find a Intruder bucket but I didn't know it would fit the Savage lens at the time. Now you do
Shame on you Suzuki morons for cutting corners with the savage.
