Those numbers are probably the highest allowed bore, without making it less reliable...Say honda did make it a 250, it wouldnt be as reliable, without redoing everything else in the engine.

 

It's all about marketing and nothing else.

The CRF230F wasn't called a CRF250F because it is an updated XR200R and not a de-tuned XR250R.

The CBR954RR is actually identified as a CBR900RR within Honda. That class has bumped up the displacement each year and while the decal on the bodywork may change, the official classification has not.

Regarding the Recon,......Yamaha does the same thing with it's BearTracker [Now Bruin 250]. It's no where in the 250cc ballpark either.

And if the YFZ450 quad doesn't exactly share the same measurments as the motorcycle version, should you call it a 440 instaed like Cannondale did??

It's all about what looks good on paper and which class, models of the competition fits into and nothing more.

 

The Yamaha Kodiak 450 is only 422cc. That's closer to a 400 than a 450 if you round down.

 

Of course they are going to round them off, but they almost always round up. Only a few cases that they didn't, such as the Kodiak 400 (401cc) and Arctic Cat 375 (376cc). I guess the 454 was the only one that wasn't divisible by 5.

 

3cc's off is no big deal, but 21cc's of is a big deal when you are talking about a 250cc quad. I was not talking bad about hondas, but was just wondering what I have observed. But, of course that requires you reading my entire thread in which I clearly stated that I like hondas and am not bashing them. But I guess you are the type that only see's what you want to see and nothing else. Some people are just LOZER.

 

Wasnt the Prarie 650 actually around 633cc or so? Its not like honda is the only one and I dont know where you have been for the last 10 years but it sure isnt a new concept or practice by any means. The reasons for this are numerous but typically its so the machine can be put in a certain class. These machines are classified by the size, power, and features that it has. The exact engine size is not necessary to keep track of because its not the only thing that makes the bike. Also, its terribly difficult to remember the exact engine sizes for all of the atv's you are looking at, and its still not important unless you are looking at 2 versions of the same engine like in the prairie 650 and 700 or the honda rancher 350 and 400. Take a look at a raptor 660. The yfz 450 has much less displacement and yet is more powerful. Engine size is not as important as engine output so the exact number of cc's is not that important to keep track of, just a basic number close to the original to keep it in a class.

 

Very well put MADDOG56. I was just wondering why a mfg would make the displacement less than what class it is in. I would think that if I am the mfg and want to make a 400cc quad, that I would want the motor to be close to what class it will be in, so as to be competitive. Just my thought. And by the way, I have only been in quads for the last 4 years so that is why I asked the question......not to talk bad about another quad, but to educate myself on this matter. Thanks for the imput.

 

My 85 atc 350x is a true 350cc. well its actually 350.1cc or something like that. so not all hondas are underrated.

 

Happy to help.
