A bit of explanation regarding the front end is due.
Why a Suzuki GT750 front end?
An article in the REOC/USA newsletter some 25 years ago that someone wrote claiming a Suzuki GT750 front fork would fit perfectly onto a Royal Enfield frame got me excited about the possibility of relatively modern suspension and good brakes, so I went to the local "breakers" and bought one.
Sadly, I was unaware at the time that they originally used a really excellent four-leading-shoe drum brake on the early models. This one had the twin disks. I wish I'd known enough to make sure I got the drum brake model front end.
I don't know what the guy was smoking when he "fitted" that fork to his Enfield, but they're not a "drop-in" replacement. The bearing races aren't interchangable between the frames, and the diameters of the races are different, so you can't just use the Enfield inner races with the Suzuki outer races.
I just stashed the forks away.
So, I figured out how to do it, and still have the famous Enfield "casquette".
Cut a thread into the Suzuki stanchion tubes, and just replace the legs, but keep the Enfield triple clamp. That's a pretty simplistic description of how it was done. For more detail
