a famous marquis that produced one of the best three ever engine sounds in GP racing.

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

A breath of fresh air this morning. The famous smallest piston ever used in GP racing is to be re-created and brought back to live thanks to the famous extended family and a privet restorer.

What are you talking about? Link?
And is this related to F1, or should this move to automotive tech?

three V16 B.R.M. 1950 F1 cars are to be made from the original drawings still kept by the Owen family
it being the 70th anniversary of the founding of the BRM team

unless the OP has in mind some other GP car having pistons smaller than the 47.8 mm pistons of the BRM

The 135 degree vee angle even firing V16 had an unique ignition system. Firing each cylinder through a small aperture was a 14mm Lodge spark-plug, spark generated by battery powered coil ignition system. A 4-cylinder distributor was driven from the front of each of the 4 cams and supplied with its own spark coil. Each of the 4 distributors had 3 sets of points, one made contact, one broke-it and one (manually selected) gave a retard timing for starting the engine.

The BRM V16 produced an engine sound that stands on all ever engine sounds.

FIM stands for motocross world championship and not formula one. As far as I know, and I stand to be corrected. The smallest diameter pistons Honda ever used in their F1 engines were those used on the RA272E 1.5-LITRE V12 of 1965 having a diameter of 58.1mm and paired with a stroke of 47mm for a cylinder capacity of 124.583cc. On the other hand. The BRM type 15 1.5-LITRE V16 of 1951 used 49.5mm pistons paired with a stroke of 48.3mm for a cylinder capacity of 92.967cc.

what a lot of smartarses !!!

the smallest GP motorcycle pistons were of course the (50cc) Suzuki twin's 32.5 mm
unless we count the never-raced 50cc GP Suzuki 3 cylinder's 28 mm
or the never-raced 50cc Fitz-Ray 4 cylinder's 25.15 mm
(Honda have never used pistons smaller than the 33 mm of the 1962 RC112/1963 RC113)

Anyone interested in small pistons and bikes, this is worth a read

It was 34mm x 27.4mm, but ran 22,000rpm and an eight-speed gearbox in 1964

the BRM V16 indeed sounds sweet. I tried to post a couple of sound files but they wouldn't play on this site. :(
HTTP://www.stradsplace.com/SOUNDS/brm_v16.mp3
If you click on the link a player opens but doesn't play BUT if you click on the three dots on the right side and hit download you can open the file. Got a couple of others but it's the same hassle.
