Altissimo right light on sfc fairing.

Possibly used in endurance racing for better recognition at nighttime? Most racetracks run in clockwise direction, RH side only visible from the pits.

That’s exactly what it is. These lights were used on the fairing of the police models of the 750, but a single one was used at the Bol d’Or 1971.

Looks like a steeper inlet angle than std small valve heads - for 1971 perhaps it was the precursor to the big valve heads that went onto the SF1 in 1973?

Being the last 24 hour race of the season, Laverda tried many new things on the Bol d'Or machines. The most prominent was the different shape of the tank, which was a work of art, and still made of aluminium. I have an original one in my collection for a future project, hopefully. The tank was more slender, offering a little more comfort for the rider.
The team mounted the chain oiler on all 24 hour races that year. The adjusting of the amount of oil was done by a fuel tap. It may have succesfully lubricated the chain, but it would make a big mess too.
All SFCs had big valve heads, and the Amal carbs were mounted on special angled steel manifolds.
Another good mod was the pedals not pivoting on the footrest. When crashing the bike the pedals were more likely to function with this construction.
For this race an 'under the engine' exhaust was used for the first time.
Also note the extremely long front brake lever which was commonly used in combination with the Ceriani front brake.

Fascinating machines they were..

That footpeg idea was pretty smart, I did the same to my Pantah. One tiny tip over braking a footpeg would have resulted in being stuck in whatever gear it was in. Chain oiler was smart as well, before O ring chains so lots of chain wear. I will have a look at the hip directly over the ankle, the best move comfort-wise I have done is lowering the resets 30mm, that's never going to work on a full-blown race bike for obvious reasons. Racing definitely improving the breed.
 
It looks like the footpegs are lower as a result as well. more comfortable. Also looks like an extended lower clutch lever, the first one I saw was on an SFC in Melbourne an Italian bloke had just brought in in mid ´70s.
Not many people realise the advantage of mounting the brake lever (disc or drum) as far in as possible to give the most hand leverage possible.

Oh, I see already a 1971 Bol replica arising!;)
