Please also note the spare spokes taped to the front mudguard stay.the air pressurised container on the front down tube to inflate tyres.and the plug spanner fixed to the rear down tube. Ray

That picture is in my copy of an Osprey book about the ISDT - it's captioned:

"Eric Chilton's 650 BSA being prepared for the 1958 event. Riding in the BSA works team Chilton's machine had a Road Rocket engine with reduced compression ratio in a Gold Star frame. He was destined to win a gold medal"

So in fact an early RGS!

The most notable BSA participation in the ISDT was perhaps the 1952 event where 3 stock Star Twins rode about 5,000 miles across Europe including winning 3 Gold Medals and collecting the Maudes Trophy.

Also notice extension and to centre stand, and plug spanner stowed where pump fixes.
And does the young fellow look a bit like Brian Stonebridge

Yes, that extension might have reduced my struggles with the back wheel.

He was riding a 250cc Greeves that year but I expect they all worked together.

The ISDT was known as the "Olympics of Motorcycling" and I'm always impressed by the sheer toughness of the riders (if not always the machines). One bike I've always rather fancied is the MZ ISDT Replica.

Hi Everone

Is that a gear lever bolted to the top of the rear suspension unit?, hope this photo will give some one some ideals to reproduce one it would look great.

Regards
Nick

not sure about a gear lever Nick but definitely an extra bit for some use or other,also what could be a tommy bar strapped to the bottom front mudguard stay

Hi Guys
  Here is a silly question.  Why would they use a goldie frame.  I would have thought that they where made from the same tubeing.  The only thing I can think of if for the use of single sided brake.  Then again they could use goldie forks and swingarm.  Wickled cool anyhow.  Jeff

I'm not to familiar with the B frame but you could be right re the single sided brake if it made removing the rear wheel easier, I don't know if this is the case or not

The crinkle hub does make removing the back wheel much quicker as it's essentially just a matter of taking the RH spindle out.

I returned to this post because I thought Ray's "air pressurized container" might actually be a pump. Nevermind, not why I'm posting. Wondering why I couldn't recall who Ray was, I saw that his last post was in 2015 and he did not post frequently. Well, a little seach of his name and home town appears to show that Ray passed away in March of this year. At 82, could be anything.  RIP, Ray.
