They have repop springer 6 under. 18" .
Zero engineering goose necks their frames to use such a short springer and yet to keep modern EVO engines. Don,t sell frames any longer.
i wonder where to find a frame that will go with such a short springer ?

Pretty sure that chart is inaccurate, since the VL is slightly longer than the later springer. 1" longer from one source, 1/2" longer from another. Either way this depicts the VL as being actually shorter than the inline. Maybe this chart is from a catalog of repops?

I got that chart off of the JJ . Not sure where it was sourced from before that.

don't forget to look at stem size Harley's are an inch dia

triumph's were 7/8ths if I remember right
there are kits to change neck sizes I have even made bushings
to press into the neck to fit the size of cups I wanted to use
I have no idea for of sizes for other bikes
good luck the possibility's are endless

Ahh, I guess that does make sense that the rake doesn't change haha. Thanks for the input. Are you able to say, more or less, how a bike that is "tipped up" handles compared to one that isn't as tipped? Or do you know of any forum threads that discuss this?

it seems when the bike is tipped up with longer forks, at slower speeds or standing still, you get more fork flop. but at high speeds it's very stable. I think Andy Carter of Pangea speed used to write up something about it. I think it was in one of the show class magazines.
