I've got to quit reading this. I am so jealous. I can't believe I cannot make it on this one. If we get the #50 cabin then we'll have a fourth bed !

Those cabins are not pricey even if we need two of them !

Paul , RE makes a GT version that is not far from the one you found ! Also , did you know they make a 865cc bolt on kit for it ? So it's an over-bore bike to begin with with 4 valves per cylinder. There is also a "+20%-Performance Cam" easy to get. And a DNA air intake kit that doubles the air intake capacity . There is a multitude of Free Flowing Exaust systems for it too. For under $8.5k , you can buy a new one , add all the HP add-ons and have a new Scream Machine ! The GT and Interceptor versions are just a little over 400 pounds. My Super Meteor and the Shot-gun versions are a little over 500 pounds.
It looks like this dealer bought-out some New-Old-Stock
https://www.allsportinc.com/--inventory?make=royal%20enfield&pg=1My factory bike is only 48-HP , but that's more than enough for anything I want to do . I've grown lazy through the years !

I've got a Blue one of these , it's a little heavy for me but I put some Lowering shocks on it so I get by just fine.
