[@Banditmanuk]

Dick Shepherd is such a fountain of knowledge and so enthusiastic. Managed to spot myself in the crowd. Great quality video yet again 👏

You're right Banditmanuk, we're heading up to Triumph again next week, come and say hello! Thanks for the nice comments too :)

[@Banditmanuk]

@@TheClassicMotorcycleChannel Sadly cannot make this next one but will keep a look out for your vid. Cheers

The original Grand Prix (and Trophy) engines had parallel exhaust ports because the only alloy top end available was originally designed for an "industrial" engine used in RAF auxiliary generator sets during World War 2. The engines were fan-cooled and shrouded. The parallel exhaust pipes saved space and the alloy head and barrel saved weight, both important considerations on an aircraft. You can see the blank bosses on the barrels, used to attach the sheet metal shroud, in the photograph of the 1947 bike in the video. IIRC, the first GP/Trophy engines used surplus "generator engine" parts, and those bosses were drilled and tapped. Later engines used new castings from the same pattern, but, obviously, it wasn't necessary to drill and tap the bosses.

High class English bike high class engineering Triumph is a cat amongst pigeons love that sound. shepherd sir highly appreciate your knowledge. I have ridden Triumph Tiger 💯 1958 model which belongs to my Grand father in Bombay

[@fearsomename4517]

Such a beautiful race machine. I had a Grand Prix square barrel motor, very rare. I also restored a '50 Thunderbird, I miss it dearly.

[@christoms5050]

I think I had one of these back in the 60s it was sold to me as a racing T100. It had cast iron head and barrel, oil tank on the RHS, sprung hub etc. I would like to send you a picture but not sure how to do this Cheers Chris Toms NZ

Classic history

[@grahambird1570]

The Big Ends were half an inch bigger than the Previous Motors in this Unit !

[@ducatimale]

Oh. And. Wonder why Triumph went from Smith clocks to Veglia in the end...

[@RichardASK]

Don't forget, that all MOTO 2 engines are Triumph 765cc units. That's a whole Grand Prix class powered by Triumph.

[@tassartbuzz]

Don't know why they don't make modern bikes look and sound like that anymore.

[@dogpaw775]

Fruity !.

[@dogphlap6749]

Thank you for a very interesting video. Looks like no rear suspension other than the springs under the seat. If I was to ride that bike I'd be scared to death my toes would be chewed up by the primary chain.

[@rickmancr]

The suspension, such as it is, is inside the rear hub. The indicator that it's a sprung hub is that the spindle isn't in the centre of the hub. Not one of Edward Turner's best ideas. :-)

[@dogphlap6749]

@@rickmancr Thank you for that.

[@rstmg60]

Why do rev counters on these old bikes always move in that way rather than smoothly?

[@rickmancr]

It's a "chronometric" mechanism. Later rev counters and speedos are "magnetic".

[@rstmg60]

Thanks.

[@miketiller8430]

What’s with the tape on the spokes…..

[@rickmancr]

Probably covering lead solder wrapped around the spokes to balance the wheel.

[@stevehollis9121]

Got me buggered why they rev em out if it's gunnu idle. Sound's nice tho dunit.

[@rickmancr]

No choke, so no idle until it's warm. The later Amal GP racing carburettor doesn't even have a throttle stop to set the idle with.
