Sweet! That's like the whole world! And you and variable9 pretty much spearheaded it! :)

So how does the power of a 2 stroke bike compare to the power of a 4 stroke bike?

Twice as much power per displacement size, plus MUCH less weight. A 1000+CC 2 stroker would be a monster engine but probably hard to maintain and keep from blowing it self apart.

Fap Fap.



IF, and I stress IF, if was going to fap fap over a bike, this would be close. AND IT'S A PARALLEL TWIN? Since when were they sexy?

So Aprilia knocked BMW of the perch, now Kawasaki has blown them both away with a 210bhp, litre, 198 kegs (wet) monster.



And, Armyowalgreens, if you have to ask the question; ride one! Steal it if you have to! When you find the right two-stroke, you'll wonder why everyone talks about sex. They are the drug. In fact consider an RG500 as the heroin of bikes. It'll give you a rush as big as the Kawasaki (above), but it'll kill you too. Which is what makes Doohan and Sheene the two Gods of motorcyling.

Here is another tid-bit for those interested. Lawnmowers were mentioned a page or two ago. My great uncle (Merv Victor [- aka Victa] Richardson) invented them - no $hit!

Maybe 50% more per displacement, but they will burn more fuel per hp generated, and have nasty emissions (lots of unburned fuel and burned oil goes out the tailpipe - hence the nickname "2-smoke"). Also, they generally have a narrower rev range where they make usable power. They are lighter and mechanically simpler, but they are dynamically more complicated and harder to tune.

With a 4-stroke, if you want to shift peak torque farther up the rev range, you change the cam and maybe intake & exhaust. On a 2-stroke, you get out the porting tools and start cutting into the cylinder. Guess which one is easier to put back if you don't like the result? ;)

Today's 800cc GP 4-strokes are making a lot more power than the 500cc 2-strokes from 9 years ago, and they're easier to ride. Get Rossi's famous overview of the old 500cc bikes about 20 seconds into this clip:


This might sound like I'm anti-2-stroke, but I'm not. They're finicky, hard to ride, hard to tune, but just plain bad-ass. Nothing else will ever be as cool as a radical 2-stroke. If they weren't so absolutely horrible environmentally I'd have a collection of 'em, but I couldn't live with myself riding around leaving that cloud of poison behind me.

I saw this bike last night on American Choppers. It's messed up, and an abomination, but there's something I can't help but like about it:







Sorry, no good pictures of that rear suspension.

Like, WTF is this? It's a chopper! It's a bobber! It's a hill-climber! It's a hot-rod! It looks like 5 guys each designed one part of the bike and then threw it all together. Still, it has a certain charm IMO.

The paint work on the tank is pretty amazing, but that stupid cheap looking plastic skull on the front looks really dumb.
