What yamaha xj650 do I own?

So therefore---it's not a Seca.

It's a European XJ650.

 

Why no Seca in Europe? Too many Spanish speakers? Would they all wonder why the bike is called "Dry"? Without the "Laguna" part, the name is sort of strange.

 

Yes. 97% the same machine though.

 

Marketing. Model names are typically market specific. Take the Mazda MX-5 for example. Mazda Miata in the U.S., Eunos Roadster in Japan; same car, with minor differences to meet regulations for the specific market.

 

I have a Buick Allure, otherwise known as Lacrosse.
Apparently in Quebec, Lacrosse is a slang term for tossing off, LOL.

 

Sounds sort of alluring!

 

I have read through the whole identification forum and am still confused.
I know it is a 650, and not a Maxim.
Does anyone know what type my bike is if my shorty identification number is 4K1-000919
Sorry if this is all a pain.

 

It’s just an xj650r that in North America is called a Seca. And the letter after the “r” is the year designator.
So H=81 J=82 K=83 L=84
The only oddball is Canadian model is an Xj650rjc “C “ designation for Canada only in 82 for second series of bikes that had yics engines.

Yes!!
That's her! The seca.
Thanks so much.
overtime I input the shorty ID into a linked convertor it would come up with a 550 maxim.
Thanks for the help, now i can get back to rebuilding her.

 

US had Maxim & Seca. Europe had Maxim & XJ650
Seca and European XJ650 = almost identical

 

What maxim did Europe have

 

I think any Maxims in Europe are gray imports
They were marketed for NA only I think

 

That's what always thought, too, but Andy indicates otherwise, so was piqued to find out what he knows

 

maybe the ones brought onto the military bases, then left behind.

 

Bingo.


A lot of XJ700's can be found in South American, too. Why?

"all of them were imported in the 90's (at that time the government allowed for a short time to import used vehicles from abroad)


Why are there so many XJ650 Police bikes in Nepal?

"there were 300 XJ650's gifted by Japan on the occasion of King Birendra's crown ceremony."


As is so often the case, the bikes lasted a lot longer than the King did:

Sorry, haven't been here for a while
XJ650 4KO (US Seca clone) and XJ650 Turbo were direct imports. Not sure about Maxims, they are much rarer in Europe but they are around. It would be interesting to see where they are located geographically in the UK, there are/were plenty of airbases in East Anglia

What I was trying to point out is that the 4KO and the Seca are to all intents and purposes the same thing

 

lighting system may be different . you have an on off switch for the head light? also an oil cooler?
oil cooler is an option in US and we have to have lights on always

 

Yes, also carb jetting varies but to a non-forensic eye, same bike
