In the late 50s, early 60s, I had a '53 Harley K Model, 45" flathead, but with the Sportster lower end.. The KR was a Roller bearing lifter model for the miler fat track riders.. There were KH, KK's, but mine was pretty basic, bought it from a local Cop as he moved on... But I had it up to 120 along the way, new freeway, open road, buddy in his '56 Chev eggin' each other on... Very light, very small patch of road contact... .Crazy kids... But we all hit the Drag strips, hardtop races every week... Who sweated the future? Picked up a lot of tickets back then, Cops loved snaggin' us donors!
Replaced it with a Triumph T110, 40", popped it in a light, rigid frame, as minimal as I could get it, lower geared, top end was maybe 70, but it got there quick... But, once married, it sat, I sold it off.. Did without until the '76 thumper... It's living under a tarp in the shop... Needs fork bushings, seals... Someday...
