Correction according to the Innnernet (country twang) flat fours are God's chosen cfg

The benefit of using an horizontally opposed engine versus a V engine is that it provides perfect balance because each piston's movement is exactly counterbalanced by the corresponding piston movement of the opposite side. These engines can run perfectly smooth and free of vibrations with a four-stroke cycle, regardless of number of cylinders, and do not require the counterweights on the crankshaft to balance the weight of the reciprocating parts which are required in other engine configurations.</a>

KPaul was right,Take that back 90 deg V-4 is narrower and has perfect primary balance

The earliest VF series engine was designated the V45 for its size (45 in³ or 748 cc), was very narrow being only 16 inches (406 mm) wide, and had perfect primary balance making for a smooth, vibration-free engine. A smaller V30 (500 cc) engine and a larger V65 (1100 cc) engine were also available, the latter becoming known as the fastest production bike in its time, and the original competition for the famous Yamaha V-Max."

Blitz I love it when I am right...

The V-Max has a 70 degree spread between the cylinder banks, and therefore lacks the inherent primary balance of the Honda's 90 degree lay out. VWW

I don't know. Yamaha seems to sell pretty much all of their V-Max bikes. It's a cash cow for heaven's sake and in the Japanese motorcycle market, that's a rare thing indeed. I don't think Yam will make radical changes to the V-Max when that product is selling well. Anyway, it works for Harley (sorry, I couldn't resist incorporating Harley into this discussion!) Just my 2 centavos.

Re: On the 8th day God created the V-Max

I believe there were a couple V4 diesels in the mid/late '80s, but h311 if I can remember who and what models right now...

Is the new Liberty Diesel and I or V, anybody?

How much power.......

....is it prudent or safe to keep stuffing into street motorcycles?

If we bikers don't stop demanding it from the manufacturers (do we even really need it?) then we can all rest assured that the insurance controlled govements of the west will limit it for us!
