Well?
Question, if there are two SUperbike engines, same bore & stroke, same head design as much as possible etc. only difference is one is an I4 and the other is a V4. Are you saying the V4 makes power all through the rev range but the I4 does not?
...
I, for one, am interested in seeing what Yamaha does with an inline-three. I like what Triumph has done with them.
If the bore and stroke and valve sizes and cam timing and intake runner lengths/diameters and airbox dimensions and exhaust primary header pipe lengths/diameters are the same ... then they will have virtually identical torque curves, with only minor discrepancies arising from the irregular firing order resulting in some overlapping intake/exhaust strokes and some gaps between intake/exhaust strokes. They will sound very different due to the irregular firing order.
In a superbike with the engine installed transversely as usual, the inline-four engine has a packaging issue because of its width, and the V-configuration engine (doesn't matter if two or four cylinders) has a packaging issue because of its length.

. Those people who says twins don't have the performance had best get their head checked. Mind you, my other friend's 2011 ZX10R (with a slip-on and ECU unlock) walked away from it pretty convincingly
I test rode an inline 3 tody & must admit, pretty impressive![]()
As did I (MV F3 675cc) but unfortunately, while it has a lot of HP up high in the RPM range, it has nothing anywhere else, especially compared to my 999cc 75* twin. I'll keep my twin, thanks.
The F3 was really raw & unrefined. There was a flat no-powerband from 3-5k rpm. The throttle tube also needed adjusting.
I believe the 675 Brutale was also a triple. Really loved it! Much smoother, more refined
An unrestricted '11 ZX10R is on par with a S1000RR in terms of top end power. I expected nothing less. But keeping up with the '09 was a big surprise, since it's supposed to have a lot more power. Once again, torque and gearing mean much more than dyno numbers.
Doesnt the 09 have a much better midrange than the 2011?
Im guessing two different riders huh?
I fixed it for you.
