Why is the V-4 so underutilized in motorcycles?

Cylinder configuration really doesn't matter. A lot of other stuff does matter which determines and engine's T and HP output vs RPM.

Well, engine technology is better today ... but if you want to compare the Honda V65 to a Yamaha XSR900 (inline 3), the T and HP curves are about the same. The V65 is 1065cc and the XSR900 is only 849cc (51.8 cu-in). If the XSR900 was 1065cc it would smoke the V65 V4 in T and HP.
Honda V65 (1065cc) V4.
Yamaha XSR900 (849cc, 51.8 cu-in) I3.

That kind of stuff also depends on the gearing of the machine.
Y'alls like to argue online way more than I do apparently. Jeez.
Beyond everything else being thrown around here, no one has really yet mentioned packaging. The rear cylinders on V-twins and V-fours get in the way of rear suspension bits. It can be done obviously, but having more room back there makes sorting out the rear end a lot easier as far as shock placement, swingarm length and pivot location, etc.

If a V4 configuration is so superior to an i4 one in every aspect, the why don’t we see it in small sports cars like Miata, S2000 or BMW Z3? Who would not love a little sports machine that can scream to high RPM and have plenty of low end TQ?
At the very least, Honda would have attempted such a feat given their experience with V4 engines in their motorcycles. Why they have not done so?

I had a chance to buy one of these NR750 in 93 but it was too much wood. IIRC it was 70K DM at the time. The ultimate V4.
Because cagers close their wallets with a torque wrench and the current Honda CEO has no sport in his blood.. Mr.Honda would...

No You Didn't!!! How on earth did you find one of these things for sale? Seventy Thousand Deutsche marks would be a bargain with today's currency conversions. That thing never did for Honda what they wanted but it was an engineering masterpiece none the less. I thought they'd all be destroyed and the blueprints shredded and burned. I've never even had the pleasure of seeing one in person. Great picture!!
Yes the ultimate V4... so far nobody has loss money investing Mr.Honda's exotic V4s...
Me and Jason's NR750 at Bubba Gumps
Jim Granger's shop
Comparing a new engine to a 40 year old design is hardly an apples to apples comparison. Compare these two engines, at the same size, with the same era design technology and the V-4 would blow this engine away...in fact, I think Yamaha made an inline 3 back around the same time the Honda V-4s were coming on line and they didn't compare to the V-4s...
When I bought my SC24 new I bought the 92 in 93 as a leftover because DCBS was new and I didn't want to be a guinea pig. Anyway they had one right there in the showroom for sale, quite a few dealers had them in Germany. 70K DM was a lot of wood in Germany.
In the words of Steven Tyler... Dream On... I can't argue outside of facts
If I threw as much talent and money at a rock it would likely win too...
Nice reply... LOL. I see you're actively working at destroying this site too... keep the streak going with the delusion
Here are a few which, according to you and BLS are physically impossible. Note how the S1000R even stays right with the Tuono 1100 across the board despite giving up 80 cc. I could surely find others but you'll likely deny these and all others anyhow. Again... Dream On

Pretty obvious logic and facts hold no weight to the deluded... lol
In the current models, the BMW S1000RR makes more HP than a Yamaha Vmax. The 2021 (last year made) Vmax is 1679cc and the BMW is 999cc. Yes, the S1000RR is a hyper bike, but it's a smaller displacement inline 4-cyl that makes way more HP than the Vmax. Of course their torque and HP curves are different ... but fact is the 999cc engine is making more HP than the 1679cc engine. What other current V4 engines today make more HP than the Vmax? Cylinder configuration really doesn't matter. Everything else associated with an engine design does.
An old 2008 Hayabusa (which is 1340cc) basically made the same RWHP (180) as the 2021 Vmax. Of course they made HP in a different way due to how they develop torque, but in the end the HP and gearing is what matters.

Added info. If you go search for the HP numbers between a Yamaha XS750 triple and a Honda V45 (750cc) Magna back in those days, they were basically both rated at ~75 HP ... far from the V4 "blowing it away". Again, the cylinder configuration really doesn't matter when it comes to making HP.

I think you're missing what I'm saying. The V-4 engine configuration is the only one that produces both an abundance of low end grunt, AND high RPM HP. No other engine configurations do this to the level of the V-4. The XS750 didn't produce
anywhere near the low end grunt of the V-45...
The Busa and BMW are one trick ponies. Neither of them make anywhere near the low end grunt of the Vmax...
