Well?
inline or v twin?
- Thread starter ajaxguy
- Start date
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.
I, for one, am interested in seeing what Yamaha does with an inline-three. I like what Triumph has done with them.

I used to ride in-line fours, but as my user name says, not any more. IMHO: When, (and if) you reach a point where you want and need "more" from a motorcycle than what in-line fours offer, only then you will be *ready* for a twin. I reached that point after 3 in-line fours, and one v-four. For me "twinswin." I'll probably never go back, unless I'm buying a vintage bike. But to each his own.

I lined my Tuono up against my friend on a 2009 ZX-10R the other day (on a test track, of course) and it took him all of five gears to pull any distance on me. 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 did three goes at each bike and it was consistent.
Then I traded off... and the Tuono is a riot, while the zx10R is... kinda sterile, until you have it into supra-legal speeds. I was eager to trade back. So was he... riding a big with big wide bars takes lots of body english if you want to ride it sporting, otherwise it feels like the front is a long way away and very vague. You need to move your weight forward and down and ride it like a sportbike, which will give you a LOT.
Some video of a bike just like mine with a dapper guy riding it at Deal's Gap. (Cut to around 13:00) No place to safely pass the backmarker.

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.
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 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
I fixed it for you.
Doesnt the 09 have a much better midrange than the 2011?
Im guessing two different riders huh?

Yes two different riders. And to tell you the truth I haven't ridden a 2011/2/3 ZX-10R so I can't say. Or if I did, it doesn't stand out in my mind.
My Tuono has MAP2, de-restricted airbox, -1 front sprocket and Akrapovic slip-ons for reference.

I was surprised at how much it pulled past 6krpm and it kept climbing but ya anything below that was ummm not impressive. But I'm coming from a twin so totally different totally different from what I'm used to. That F3 was "twitchy" for me, but the F4 man really smooth powerband. And the sound holy crap one of the best things to ever come out of an exhaust. Really enjoyed the F4, I can see myself riding that bike in the future.
