1973 Suzuki GTR550

Posting a few photos of a bike a friend built last winter. It's a 1973 GT550, ever so slightly customised to a modern caferacer/streetfighter, hence GTR. There is a lot of attention to details in this bike, and quite a few challenges and complexities were met during the building process but there are no compromises. There are parts from all Japanese brands and one Italian, and some aftermarket custom and selfmade parts. Too many details to list, I let the pics speak for themselves.

Is that done by the same guy that did the GT750 with the radiator mounted behind the engine ? Some of the styling is similar and he was also from Norway.

No, none of the 750's he has built have that type of configuration.

I'd like to hear video of it idling.

That can be fixed. Too bad it's difficult to catch the sound while riding behind it.

Very nice,
But tell me. why does the H1 have a drum brake on the front.

The early H1 from 1969-1971 had front drum brakes. The effect was, well.. dubious. From 1972 with the H1B model it got a disc brake. However some 1972's were sold with drum brakes, as they were assembled with leftovers from the earlier production (brake, engines, ignition and some other bits), and named H1C. These are very rare today.
The H1 in the picture is a 1971 H1A.

It's a one of a kind. I've seen many GT550 customs but very few as well and thoughtfully built as this one.

Pointless the early H1 having any front brake at all as the front wheel was usually in the air.
