European GSX 1100's, were they restricted?

[DaveV65]

I'm just looking at a 1984 GSX11 EF in Germany, were European versions restricted at all?

[Gixer1460]

Some were, some weren't! French were and if sold into Germany it could be but I think 'native' German bikes were 'full fat'.

[DaveV65]

Thanks Gixer1460, I'm guessing any restriction would be fairly rudimentary and relatively to reverse.

[DaveV65]

missed out the word "easy"

[Gixer1460]

Suzuki main restrictions were in carb tops and jetting but exhaust and ignition restrictions not unknown!

In case of the EFE the restriction is done by the cams.

Thanks Arttu

I did not know that!

[Arttu]

From the service manual. This also gives some hint where the restricted versions have been sold but I have understood this isn't the complete truth...

This is a super study into the cams, start at p29.
Sorry, it's in German.

I'm pretty sure German bikes were restricted to 100hp.

But with the GSX1100 that was about the max HP 

[Reinhoud]

Dutch bikes were unrestricted.

I seem to remember reading on another thread that the restricted cams were stamped with a ‘D’ for Deutschland.

According to the document, there are at least 3 types of cams : 100/111/125 HP, the D cams being the faster ones.

Ah okay. I knew there was a D-stamp in there somewhere.

D stands for "Da Beasty Ones"
