This is from a reliable Honda source.

Sept 10th in Vegas, Honda will be releasing the TRX450R. Based on the CRF450R motor, with modifications for the four wheeler. Honda states that this will be the most advanced bike on the market.....

Keep checking the honda website for information. This is going to be a great year for ATV's.

That would kick butt. Although I had a 450 and they are a lot of maintenance. I can't see it as much of a daily rider.

Well it sounds to me like the YFZ really is intended to be race-only... I mean, would you want to have to put race gas in your quad as a daily rider? I sure wouldn't. And heck, with that super-high compression ratio, it still doesn't make all THAT much power compared to a Predator (piped for piped). Puhleeze.

Let's hope Honda keeps in mind that people will want to ride them a lot in addition to just racing, and keeps the thing sane and easy to maintain. If they do, I will likely get one.

I remember this time last year the same thing was being said. Honda had it hyped on their website and everything and they released a couple dirt bikes and a freaking water craft. I will believe it when I see it. I have always been diehard honda fan until I bought my Pred. Honda has to do something really special to get me to switch. I will say this to the people bashing the YZF. I race with a guy who bought one. He ran a cannondale prior and did fairly well. Since getting the YZF he has kicked everyone's ass. THe bike pure out flies. I'm a bigger rider and don't think it is the right size for me but it handles great through the woods. He compared it to a 250r

One of the best things about any Honda is the reliability. I'm sure Honda won't shy away from that. I hope it really is an R replacement. For years I haven't been able to understand why they wouldn't use the R chassis again. It is still the most popular chassis for racing. Every aftermarket company models theirs after the R geometry. By looking at a 450 motor, it sure looks like it could fit. It is a small motor. I hope they did include some anti dive geometry like polaris too.

As far as I am concerned the predator is the best sport quad for the money,and that is goin to be tough to beat. Polaris has done a good job with this atv. Dont get me wrong I do like Honda,I have had alot of them.They also are an excellant quad,but you know it will be alot more money. Probably have to put alot of money into it to make it race ready.Nerfs,skids,kill switch,tires,and etc. We will see.

I agree that the predator is the best bang for the buck, but I asure you mine is gone after I compare the new honda against the yfz. I will make my decision on which I think is better and trade. I love the predator and am not bashing the bike at all. The predator has been the best race bike I have ever owned, and has won me some first place trophys. I know a couple of guys racing the yfz and by the time honda comes out maybe I will know the weak points of the yamaha. I know the predator is a first year production as well as the honda and yamaha will be and it might not get any better for me, but that is a chance I will have to take. For the first three months I did not have one problem out of my predator, but since I have had broke frame on both sides of the gas tank brace, broke radiator bracket, broke airbox out of frame, broke set of plastic, broke chain, footpegs bending but not broke yet, had to have the topend replaced and now my shocks are leaking oil. You probaly think I do alot of racing and no maintance but I do after and before every race and practice. Some of the problems was my fault but most of them just in the bike. I am just tired of putting money into the predator before every race. You might think and say thats part of racing...and it is to a certain extint but enough is enough. I have been spending around 150$ on average before ever race. I just got the new dirt wheels september issue three or four days ago and they had the perfect quote....."

"The yfz is a production race quad. It was built by a company that thrives on competition. Possibly, a large percentage of the buyers might not even end up racing it, but Yamaha wanted to be sure that those that do will not be disappointed. OR GO BROKE TRYING TO.".....

Once again I am not bashing the predator or think that the yfz or the new honda will perform better than the polaris but in all reality polaris is new to the sport quad production and yamaha and honda is not. Polaris has a few problems to work out and I'm sure they will but everybody knows about honda realiabilty.

I am glad that all of the quad based companys is getting compative in sport quad racing. I would like to see more people get into it. Be as popular and see it up there with AMA motocross, AMA superbike and can't leace out nascar.]

Like alot of people have said, Its a great year for quads and I hope it just gets even better.

How is what I'm saying crap? I stated FACT. The compression ratio on the YFZ is so high that RACE GAS IS REQUIRED. And the dyno numbers so far show it making around 37 hp at the wheels if I remember correctly. Compare that to the mid 40's for the Predator.

If you look at the specs for the YFZ450, the compression is 11.9:1. That setup does not require race gas. It does require at LEAST 92 octane. Even the WR450F that this ATV engine is based on is 12.5:1 and it does not require race gas either. No manufacturer would ever put out a factory quad that requires race gas. its just not practical. Not everyone that buys ATV's races them. MOst are just recreational riders and they sure don't want to pay $3-$5 a gallon for racing fuel everytime they want to ride. That would be bad for sales on any machine. Honda's new ATV will be the same. At least 92 octane.

We are running regular unleaded 91% reccomended by my mechanic who is yamaha endorsed.

And if you want to rant about the compression, even when the piston that takes the compression up to 13.1 is installed, you still don't have to run your race gas.

Even the yz450f dirt bike with 12.5 compression runs on pump gas

Please correct your so called facts.

I think it will be so tuned down due to honda "safety first" mindset that it will not be really competitive. If you look at their response in every other class of atv theres no doubt. The Rincon is a prime example, not at all up to par with it 650cc+ 4x4 rivals. I've seen the Suzuki 500 Vinson and the 500 Sportsman outrun and out mud them. I think Honda is doing what Suzuki did in the late 80's and 90's, sitting on good sales numbers and not willing to take chances.

Okay so since when is it safe to run a motor with that high compression on pump gas? In my experience with automotive motors, anything over 10:1 pretty much requires 91 or better. My own (at the time) '93 Z28 with 10.5:1 required 91 in order to not knock, which we discovered by using computer scanning software with a tank of 87 and then later with 89 and then later again with 91.

Ask any motorhead and they'll tell you that even the Predator, with 10.8:1 compression, should use 91. Why would this be any different than an automotive motor?

Also... Geoff... why has this thread suddenly become so very hostile??? I'm stating my opinions and you're jumping down my throat.

Mate,there is no hostility coming from down under.

My problem is not with opinions, but you stating your opinions as facts, when all it achieves is revealing your ignorance.

And you are the one trying to shove it down our throats with your use of capital letters emphasising your so called facts.

Mate you do a great job, I just feel you may be a little too biased.
And your bias is clouding better judgement.

Cheers mate.

Geoff.
