It is interesting that Harleys are now "nimble" compared to these behemoths.

If they keep upping the engine sizes on cruisers, eventually there won't be much of a difference between Honda/Kawasaki/Suzuki/Yamaha/Harley and the Boss Hoss.



I'm sure if they really tried Honda/Kawasaki/Suzuki/Yamaha/Harley could even make the bikes as ugly as the Boss Hoss.

And you'd have a redline of 2700rpm. Figuring a 1000 rpm (800 rpm is minimum or the plugs foul) idle you only have a 1700 rpm operating envelope. I guess the thing would have a completely flat torque and horsepower curve.



The engine got 3500hp at maximum manifold pressure. With 28 cylinders that means a twin could get around 3500/14 = 250 hp.



Heeheehee. Count me in.

As a youngster, i spent many hours on a John Deere 80 tractor. It had a two cylinder, 470 cubic inch engine that produced all of 61 drawbar horsepower at it redline of 1125 rpm. the slick shifting 6 speed moved the 8,000 lb (without wheel weights of another few thousand) to a top speed of around 20 mph. to start the beast, one first got a small gasoline "pony" engine running and then threw the accessory clutch.

Default kpaul predicts

[*]V-Twin size will reach it's peak next year
[*]V-Twin sales will start to decline in 2008
[*]WSBK will not allow 1200 cc V-Twins this will force Ducati to race its 1000cc V-4.
[*]When MotoGp goes to 800cc. The new fad will be 800cc bikes i.e. the new 750 class. Honda will create a 800 CC bike called the Inteceptor 2 based on the MotoGP bike, which will set sales records and win the AMA superbike class despite a cc disadvantage
[*]2016 the last V-Twin is made. Harley closes doors due to lack of new modern product i.e. no R&D spent, profits were not retained etc.

Default V-Twin size has a direct coorelation with GPTB waist size.

I would love to see a chart plotting both V-Twin size and GPTB waise size over a 10 year period... I bet you could have a nice linear coorelation..

Default 2500cc's, and it's for sale.

Some wacky Aussie stripped two cylinders from a Rolls Royce Merlin V12 aircraft engine and made a motorcycle out of it. That was in the mid 80's. It has been the heart of a drag bike and a streamliner.



Now, while searching for a link I found out this crazy thing is for sale.

More and more I think of Harley's as diesels. For all practical puposes that is what they are in relation to modern high revving engines.



Kenny Roberts used to refer to any four strokes as diesels. That was before the Moto GP converted to them. He was talking about racing and superbike racing compared to GP.
