What about Vincatis?, seems there are more than a few of those, -in this part of the world.

Makes sense, when Vinnie engines are becoming unobtainium, and old Duc engines are, well, old Duc engines.

Buell engines would have to be on the radar too sometime soon ??, quite good hp and spares available over the counter. Sportons and Narleys...

Be interesting to hear what the vibration factor would be like with one of those things....
 
Waste of a frame. - A nice two valve Jawa speedway engine would be a much better option !

They're out there, the lovingly restored, or stock maintained, RD350s.

Thanks for the pIc the Doug Corish Norvin, Acotrel.

No need for megaphones, I guess.

Have you ever ridden a really poweful twin with big megaphones ? A vincent engine in a norton frame is bad enough without making it bloody nasty. The combination of hot cams and megaphones can make a bike into something you cannot ride a round corners without ending up going sideways.

And thats with, what, 80 bhp. ?
Imagine what these MotoGP bikes are like with 280 bhp - and the traction control inoperative...
 
The prototype Commandos, with what I believed to be 88 bhp in "Stage Three" tune, were more than enough for riding on the street. The mind boggles at the thought of 200 horsepower in a two-wheel vehicle.

Are modern bikes really that high-powered, or is it PRBS? I remember doing a dynamometer test on one of the Villiers engines (maybe the 2T), where management were very anxious to get 25 horsepower. We did a run on an engine that had the generator removed, no gearbox attached and did a violent throttle slam that just got 25.7 HP. That was the number that went in the brochures. 16 to 20 HP was more reasonable for day-to-day riding.
 
Yes they are. the BMW 1000 sport bike is 190 HP and EPA compliant. with just a few MINOR mods they break 200 HP

Acotrei - I take your point about some big twin classics. I've seen some big Nourish Weslakes giving their riders a hard time!

You're right, it's not just about the amount of power a bike makes at the wheel. A few years back, I was offered a ride on an Erion big-bore Fireblade with flat slide carbs, where the power came in at times you wouldn't expect. It would lift the front mid way down the straight or in a corner, however careful you were with the throttle. It was a nasty b*****d and I parked it. What would it have made at the wheel- 130hp perhaps? Ten/fifteen years of development later, and litre bikes that are way more powerful - 180hp+ -than that evil Honda are easier and more predictable to ride because they have better engine management and better chassis.

Dam, I had a 2T engine in my first bike, I was conned :!:
 
When people asked Phil Irving why the Vincent was such a powerful machine with just 55 hp from a Black Shadow, he replied, "Vincents have real horsepower, not BHP which stands for Brochure Horsepower!"

BMW quote their horsepower DIN - all accessories fitted.
And, they say, not a 'flash' maximum reading on the dyno, but long term sustained hp.
Like aircraft piston engines quote....

I've seen it said that oiling the chain on dyno tests on engines (connected by chain, obviously) usually gives an immediate extra 2 hp at least.

Like that brochure hp..... !
 
And, the scary thing is, reasonably reliable... ?

Untill they get them to Bonneville ? Wonder how many runs theyed cut ? ?
Not exactly easy to use that full 700 Hp ? ? ? on the street , they tell me . :mrgreen:

Why , they could tow a Semi traler on that :!: Tickets Please . No refunds if it doesnt work . May be down a bit on tourque & Flexability compared to the real deal / :lol: Dunno what Emporer Dominc II would think of it . :shock:

British rag 'The Motor Cycle' [May 20 `37], tested this new 1000cc OHV V-twin;
"Its acceleration is without exaggeration colossal...in any ratio the terrific surge of power is breath-taking...just as the acceleration is remarkable up to 50 mph, so it is above this speed , up to 80mph & more.
There is an indescribable thrill about riding this large machine along a wide, straight & deserted main road. Sitting bolt upright in armchair comfort, one can almost immediately command any speed up to 85mph on the level.
The big machine can be swung `round bends at extraordinary angles, while bumps are ignored..."

What could this marvelous machine be?
An A series HRD? Actually no, its an H-D , knucklehead..
