"Very good. $300, please."

You know what the "SIE" stood for, right? Steve Iorio Enterprises. This was Iorio's company in Chicago before he bought out Supercycle and started Nostalgia Cycles.

I remember somebody told me back then that they were made by Laverda, and were Italian government spares. Don't know if this is accurate or not.

If I remember the entire deal correctly they were Yamaha 750 motors. The TX750 was a marketing nightmare for Yamaha and had significant tranmission and crank problems. When Yamaha discontinued the TX750 model they sent all the remaining spare motors to scrap and some how Iorio got them. Most of them had the head & cylinder fins on one side knocked off by Yamaha before they went to scrap. The side you never see in pictures. SIE offered a "kit" bike for that motor. In later ads, SIE mentioned that some had fin "damage". I remember reading somewhere that Yamaha tried to get the motors back from SIE but in the end they could only go after the scrap dealer.

I always wondered the same thing. You learn something new every day.

everything Steve Iorio sold back then was JUNK. Had a customer who bought one of SIE's Rigid chopper kits for a Shovel, Nothing, and I mean NOTHING was straight or fit correctly. Chrome was junk,frame was tweaked, mounting holes were off, And the only poorer quality forward control mounts I ever saw, came from Superior cycle in NY in the late 80's. If you put pegs on them and pushed forward with your feet they bent forward, First time. The return policy was a nightmare of excuses and phone disconnections. The customer ended up spending almost another Grand making it work. Only place worse was harley nostalgia.

If they even lasted long enough for those problems to show up. The first problem to arise was the counterbalance shaft chain tensioner which exploded and derailed the whole train.

So that's the same guy that was behind the Super Vee, huh?

Did he ever run an honest business?
