I came here to post this and @MSchu1 is in like lightning 
For those browsing, we have some topics on the KA100 here as well:
There was some serious talk about this in December '17 (Maybe earlier) IIRC. I guess it was inevitable in a way. For folks who are looking for something that falls into that chasm between the likes of a 206 or can yamaha, and full blown TaG like the FR125, Rok or X30.
Say more about this? I’ve found both Vortex and IAME to be excellent. Not perfect (we’re racing after all), but both excellent over the years.
My main gripe so far is that it doesnt come with those cool looking jackets we had in the 90’s, nor do the nubs that are still present from the old mold has the threads for them 
Vortex Aircooled Jacket from the 90’s, this one is a VR98 to be specific
One thing that’s different with the VLR:
The ROK VLR engine can be utilized in Junior VLR (ages 12-15), Senior VLR (ages 15+) and Masters VLR (ages 32+). With its implementation this year, watch for the ROK VLR to make its way to select national level ROK programs in 2019. Stay tuned for details.
Might be time for a KartPulse head to head analysis. My biggest concern here is for the local tracks that have adopted the KA and now will have racers asking for Rok VLR. Can they be raced together?
