If I had the space for it in my overstuffed single garage, I'd certainly go with the Harbor Freight "1000 Lb. Steel Motorcycle Lift" described here:

99. I would definitely wait for it to go on sale though, as it often used to do under the old "Coupon Regime". As recently as September 2019 you could pick one up for just $289 (see:
https://www.hfqpdb.com/best_coupon/1000+LB.+CAPACITY+MOTORCYCLE+LIFT). I expect they'll do so again one day. Mostly the good sales on them used to occur in Fall.
A common improvement that many folks make to them is to replace that lift's original front wheel chock with another--often one of those ones they also sell like
this "economy" one or, more often, you might see
this one. There's no shortage of YouTube vids about modifications folks have made to them: removable levers, slide-in side ramps for one's feet for easier ride-on, extra attachment U-bolts, adding glue-on cushioning strips to the underside of the platform to soften descents, or even air hydraulic conversions for those with wonky knees.
One tip I got from one of my favorite YouTubers, the estimable Mike of
The Mighty Garage (
https://youtube.com/c/MiTyMotorcycles) when I'd asked about his own shop's Harbor Freight lift was, "Get it delivered." Weighing in at 340 lbs., unless you happen to find yourself one sunny afternoon tearing around in an F350 monster pickup with a crewcab full of steelworkers or buddies from your old high school football team and feel an impulse buy coming on, forking out that extra $97 for delivery right into your garage seems "sensible"--unless you wanna put your chiropractor on speed dial.
But, for the time being, I'll just have to content myself with my little Harbor Freight "1500 Lb. Steel ATV/Motorcycle Lift" that I picked up at one of their sidewalk sales for less than the cost of a 12-pack of Yuengling Lager many years back, long before my Bullet, as seen here:
https://www.harborfreight.com/1500-lb-steel-atvmotorcycle-lift-60536.html. Turns out, especially if you've got an Iron Belly Bullet, I just couldn't recommend them highly enough. Fits like a factory special tool. I cannot speak for other Enfield models, but it fits my old Bullet like a glove.
