It just occurred to me that I own three V-twins; all with different angles:

2003 Buell XB9R -> 45 degree
2000 Aprilia Mille -> 60 degree
1992 Ducati 900SS -> 90 degree

Can anybody beat that? Motorcycles only, please.

Almost a tie...

2003 Buell XB9S --------> 45 degree transverse
2004 Ducati ST4S-A -----> 90 degree transverse
2003 MotoGuzzi Lemans - > 90 degree longitudinal

Thank you! Some people just don't get that. They think because the Guzzi's engine is wider than it is long that it's transverse. Grrr...

Yes. I've seen a lot of heated arguments about this on other boards. This is the way I learned it 30 years ago - it's the orientation of the crank-shaft.

Racerx1,

I think you'll win!

All you need is a BMW boxer and you would be unbeatable..

I think there were several 180-degree transverse motors built but I don't remember the manufacturer.

If somebody were to own an Excelsior-Henderson Super-X, they could add a 50 deg transverse twin to the mix also.

A few thoughts...

It could be argued that a 0-degree twin (example: verticle twin) and a 180-degree twin (BMW boxer) are not V-twins. But if you subscribe to that then 90-degree twins like the Duc, Guzzi, TL, RC51, etc. are L-twins and not V-twins. Of course then this would make your American V-8 engines L-8 engines instead.

Has a manufacturer ever built a twin that was greater than 90 degress but less than 180?

Probably not. Over 90 degrees you have a very innefficient use of space, and don't get the primary balance you get with a boxer.

I always thought the old Honda Silverwing was a 90-degree config?

The final production version was an 80 degree V with the heads tilted inwards (I think it was like 10 or 14 degrees). Although I think the prototypes where indeed 90 degrees.

Who makes the triple? Thats gotta have an excellent exhaust note.

Hi,

OK, I have:

a few 45 degree harleys.
a 90 degree Duc.
a 90 degree Briggs and Stratton V twin. (I count it as a bike, it's in a minibike frame)

I believe the triple is one of Jim Feuling's creations.
Here's a link:http://www.motorcyclecruiser.com/roadtests/w3/
Oh, and add one more weird transverse V-twin to the mix: Honda Hawk GT 650-------52 degrees

I think the metric cruisers come in many different configs - except 45 degrees. I think this restriction was to keep HD from suing - although I don't know how S&S can market an engine that is almost an exact copy???

A Suzuki ad on the back page of the local free MC magazine says the small Boulevard cruisers have 45 degree singles!
