Hi all,
Is there any way to get a bike identified from the VIN number? who to contact, etc...
Many thanks!

how long it take you to type all that?

note 1970 T120RT 750cc (more or less) supposed to be 204made

T120's were made up until 1974 last ones were T120V AND T120RV models

by the way if Dagad dont know aint noone knows

Copy and paste from another web site.

There are several that list the vin. numbers. Not sure how accurate they are.

What about an engine number starting in NU that I believe is a 650? It is mounted in a T120R Chassis with a 1968 title.

The engine numbers do not match the frame numbers.

GrandPaulZ · 10-29-2006

That brings up an interesting question: When engine and frame numbers don't match, what do ya'll think is more important to appear on the title?

I'm going to start another thread and ask that question, so as not to hijack this one.

The number series you state look funky to me 68 should have matching numbers
