If I wanted some nice high-dollar tubeless spoked race rims I'd just message them, looks like they do a lot of custom ($$$) work.
The RE 650 Interceptor is a very nice motorcycle, but it is the bottom end of the performance market. It's relatively heavy and underpowered, but it's thousands more to get the "real" hardware. At the end of the day, a set of good tires, some suspension upgrades, maybe better front brake pads and perhaps a few weekends spent at a performance riding school will enable you to leave a lot of poseurs on arguably better hardware in the rear view mirror. Few riders actually have the skillset or ability to ride their stock machines 100%, maybe only 5% of all riders. The eyesight and kinesthetic sense of traction, the focus & concentration required, most won't or can't make the effort. It's really informative to follow an Expert level rider, mounted on some painfully stock sportbike, around a course. The fast guys (and gals) are simply fast on anything, everywhere. I'd skip the $2,000 pretty rims and spend my money on training & basics. A stock looking machine is of less interest to the "Midnight Auto" boys anyway.
