Revzilla appears to have the K180 in 18": https://www.revzilla.com/motorcycle...QNXMrHukFIJ_xBvq1rcXKrsz0j1TqtQgaAsQSEALw_wcB But they might be street instead of actual race.
They are street. Made for vintage stuff and bobbers. But they have the tread pattern. That s all there is as far as I know. I’d lace up 19s.
Lace up 19’s 100% the K180 is harder than a preachers dick and generally mostly used on street trackers wanting that “look” If you have any desire to actually learn anything on flat track get 19’s and a decent set of tires.
Unfortunately my 17s are 3.5" and 4.25"/4.5" wide, way too big for Maxxis flat track tires. Shinko says theirs are setup for 3.5" rims so the front would work but my rear is still way too wide.
My bad, I just assumed little bike. We are building a bunch of 100's and I was going off of that. @Robby-Bobby is my go to for all info, he would know best.
No worries, just trying to figure out what the best way to get dual duty out of my sumo is now that there will be a track close by.
By no means are Bridgestone Trail Wings a real flat track tire, but they do a passable job for practice/training and are available in 18" and 17". I have practiced with my Dual Sport on them.
