As you can see it has "500x - 1980" stamped in the frame.
He recently bought it from a guy who knew nothing about it.

I am no expert, But that doesn't look like a Nicholson frame to me.

Nicholson frames where all hand made from chromoly tubing and did not come with Vin numbers, not a Nicholson.

Doesnt look like a Nicholson to me either. It appears to use the 200x rear swing arm. Would like to see other pix's. Nicholson IIRC did not make the 500 frame until around '81-'82.
Definitely post more pics. Interesting trike.

This is all the pictures he has right now. I can get better ones right now.
He just rebuilt the motor with a high comp piston.
All it needs is new plastics and some fresh powder coat.
That is a scary bike in not the good way, a engine needs to designed certain ways if its going to be a main stress member and the XR500 very much so was never meant to be used as such. So you are putting all the weight of the bike and rider on the pot metal cast alloy front motor mount that was never intended to do more than simply be 1/4 of what holds the engine in the frame.
You could not pay me to take that bike off a bike jump.

I would never buy it thats for sure! Someone did a terrible job at designing the whole engine swap. (Im a welder I know about metal stresses.) The horsepower alone that that engine creates seems like it should rip itself right outta the frame. Definitely wouldnt see it in my garage like it is.

Sure looks like it has gone through some shlt yet lasted a while to me.
yeah building a frame for a 100lb motor is not the time to get creative with less tubing

It's not an engine swap dudes. It's an xr500 conversion and the engine is designed to take the load of a diamond frame. The one that's wrapped around it to be exact.
ok, ill let you ride it first

John it's not a custom frame. The engine is designed for that frame. There's absolutely no reason to doubt the strength.Originally Posted by John_Neary
