Wow.. Put a R-4360 in bike!!!!

TECHNICAL NOTES:
Model: R-4360-4
Type: 28-cylinder, four row, air-cooled radial
Displacement: 4,360 cu. in.
Weight: 3,404 lbs.
Maximum rpm: 2,700
Maximum hp: 3,500

Hell yes! Can you imagine the torque on that monster just at idle? But the sound of all those cylinders... hmmm.

I think that will be the biggest thing we will miss with the up and coming electric vehicle era. Electric bikes might be fast,but they will need a few sub-woofers to make then sound as nice!!!

Hmmm....bit of a problem right there..........

I'm personally going to find it emotionally challenging when it comes to trading in my Honda on a Fisher & Paykel! Any colour as long as it's Appliance White, I suspect?

Progress... yeah, right!

Nice. Now I've seen Jet turbine & radial on 2 wheels. I wish Mazda made bikes I think that would strike a better impressive/practical balance

[nudemetalz]

Well, some of our bikes already have that sideways torque reaction.
Once you get used to it, it's not a problem. However I believe the Guzzi would be nothing like that 9 cylinder radial, or that scary thought of an R-4360 in a bike.

Getting back to what CADanimal said about P&W getting credited with every radial.
Wright tried to make an equivalent hp with a twin-row 18 cylinder R-3350. They used turbo-superchargers and the engine was notoriously unreliable.

Never heard of the famous rotary bike? Isle of Man winner or just made well know there?

I'd have this electric bike www.killacycle.com

Rotaries and Radials are UTTERLY different concepts.

Rotaries have a "piston" that is shaped like a triangle with convex sides that spins around in a circular combustion "chamber" on a central bearing. Mazda's latest rotary has the ports on the side of the chamber allowing for better exhaust scavenging, better sealing and higher compression for a much higher power output.

Radials have multiple cylinders at 90 degrees to the crank, just like a "normal" engine but those cylinders radiate out from the crank rather than being in just one or two planes, hence the term radial.

The "best" radial engine in terms of specific output were Bristol's sleeve valved offerings, in particular the Centaurus.

He knows, he was jsut carrying on delusionz statement.... Radial powered bike, jet powered bike.... rotary powered bike being the next step in cool engines to power bikes with

Yep, well aware but thanks

Of course, you can have a rotary radial as well - a radial which spins around leaving the crank stationary. Ok perhaps in a plane, but I think probably about the least practical option for a bike ...

I think the Spitfire (not the Triumph one) had one of those?

Naw Spitfire just had a regular (lol, regular and Merlin together) engine, but I do remember the type you're thinking of

I've only ridden a Guzzi once, and the longitudinal torque was a frightening experience for me, a novice rider at the time. However, still not as scary as Kawasaki's Z1300 when closing the throttle in the lower gears. The torque through the driveshaft would cause the heavy bastards to very suddenly lift their fat arses high up. Scared me shitless!

I saw those Wright radials on a Super Constellation (interesting aircraft in it own right). The exhaust pipes all merged into a fat cylinder with a turbine wheel centred in it, and coupled directly to the back of the crankshaft. The Wright manuals termed the system Turbo-Compound for reasons known only to themselves. Interestingly, the Wright's reduction gearbox spun the prop in the opposite direction to the crackshaft, which was meant to counterract the torque. I can't say whether it was a success or not.
