| 1975 AMF HARELY DAVIDSON TT-250 |


A Harley Davidson Unofficial Engineer, he was one of the first engineers to start working on tricking the late 60's and early 70’s Aermacchi Harley’s two stroke engines; Baja 100, RAPIDO 125, SX-175 & SX-250. In January of 1973, Modern Cycle printed an article titled Krizman/Harley-Davidson Enduro Models. In the article they exposed the Krizman prototypes developments specially with the 1973 TX-125 for an endurance race. Moreover they mentioned that Krizman was working on his tricked bikes during 1973-1974 for the production line of 1975. Krizman designed and modified many performance improvements for the two strokes Harley-Davidson OEM and after market racing parts; drain holes into the brakes drums, shocks variation, disk & drum brakes improvements, ignition, clutch, crank, cylinder/heads, reed valve head, frames, etc. In addition, Krizman developed his own signature pipe designs and silencer/spark arrester. Krizman was one of the leading Harley-Davidson engineers on the 1975 MX-250 prototype and the two-strokes racing bikes and very important in many decision making improvements for the two stroke program for the Harley-Davidson motorcycle in the 1970’s. How much he was involved, I do not know, but it is very clear with his “Goodies Price List” of Tricked parts for the two-stroke Harley-Davidson, that he indeed, Krizman, was very much involved and interested in all of these aspects of the development of a Harley-Davidson racing program. |
