How about an italian V12? Smaller than a 350 and chrome pipes everywhere.

Ferrari made some tiny V12s, including some 2000cc models.

Here's an example: a snarling 2-liter Ferrari V12 from the 1952 166 coupe. There were a lot of hot little Italian engines from 500cc to 2000cc in Italian cars from the '40s through the '80s. Probably some sitting around somewhere.

Subaru engines kick ass. A popular swap these days is a Subaru flat four into a an old Porsche 914 or 911. A WRX-STI motor can be tweaked with a chip to 450 hp. There are a lot of VW Vanagons running around with Subaru flat fours and flat sixes.

Default Picture This.......

A sport touring rig w/ a longitudinallymounted 4 cyl. Specifically, the 2.3L Ford that was in the SVO Mustang and the T-Bird Turbo Coupe, with a tranny from a MotoGuzzi. Kinda like a Griso, but w the 250-300 HP of which that motor is capable. Even a mild tune of 200 would be kinda cool. Big rear, long wheelbase, comfortable seating position, and the ability to bust the back tire loose at will. Also, no muffler other than the turbo, with a little downpipe.



HOOooWaaaa!

Default just simply wrong, on soooo many levels.

It should be illegal for a Vanagon to have more than 89 hp.



Just not right. (grumble,*****,moan.....)



Hhumph. Offends the sensibilities. Stings the Nostrils....

This may not be the most imaginative response, but I think that the engine in the 2007 Honda Civic might work nicely. I makes good horsepower and torque at relatively low rpms compared to current motorcycles and I don't think it would be too large to be practicial. Here are the specifications I pulled off of the Honda web site.



In-Line 4-Cylinder

Engine Block/Cylinder Head Aluminum-Alloy

Displacement (cc) 1799

Horsepower @ rpm (SAE net, Rev 8/04) 140 @ 6300

Torque (lb.-ft. @ rpm) 128 @ 4300

Redline (rpm) 6800

Bore and Stroke (mm) 81 x 87.3

Compression Ratio 10.5:1

Valve Train 16-Valve SOHC i-VTEC®

Multi-Point Fuel Injection Standard

I vote for a Mazda Rotary, like the current gen from the RX-8. Even if it's scaled down, a compact, low torque (for a car), high revving, high power-to-weight engine seems like a no brainer for motorcycle applications. In fact, if you optimized one for a bike it would probably rev even higher than it already does.



Piston engines in bikes are more oversquare than in a car, sacrificing torque for higher revs and more horsepower. I wonder what the rotary would look like if it were built from the ground up for a sportbike. Too bad my engineering background is in aircraft, not engines, though I still think it could make an interesting project/hobby.



The rotary engine has come a long way since the last rotary bikes died; it might actually have merit again.
