looks like it's only set up for touring bikes WTF ? also looks very generic cast components & parts you get from the hardware store ( edit, just noticed the other model that's cnc'd )

if you're going this route, source your own components & do it for 1/4 of what they are charging

the unit i've got is machined from solid heavy billet & annodized, but at a premium price

 

I bought a bendable funnel from NAPA. Works great.

Of course, reading through more of the thread, I see someone already brought it up and someone else posted a link. Form-a-Funnel or whatever.
