Common Issues Or Concerns On The 450R's

I was wondering if anyone here could please help me figure out what the common issues and concerns owners typically have with their Honda 450Rs. The Honda 450R is one of three quads that I am considering buying soon.

The other 2 quads that I have been also considering are the Yamaha YFZ-450, and the Yamaha Raptor 700R. Although I will say that I think I have completely ruled out the possibility of choosing a YFZ-450 due to the ALARMING amount of engine issues I have been reading about online on various forums. Even on the YFZ-450 forums, they suggest buying a Honda 450R if you want something reliable, LOL. Thats SAYS A LOT about the Honda 450R reliability when the die-hard fans of the YFZ-450 recommend the Honda over theirs!!!!

So anyhow I would really, really appreciate any feedback as to the typical issues and concerns owners have with their Honda 450R.

Also, I used to own a '99 Honda 400ex several years ago. Is the performance difference of the 450R quite a bit greater than on the 400ex?

Thanks.

Oh yes, quite a bit different.

The thing you will see if you start poking around on the forum a bit is this, 04-05 have had the reputation of the crank failing, but it is more exaggerated than it really is. 06+ have the reputation of a weak tranny, but it generally only fails at higher HP levels, and again, it is more exaggerated than it really is.

All years are reliable and a blast to ride, and I imagine you would be happy with any year.

Hoser said it very well but he forgot to add that you will probably want the HRC kit if your really want more quad than the 400 was. I had a slightly built 400ex and when I got my 450 I was bummed cause that power was NOT what I was expecting out of the 450.

But after I got the power up kit I was very happy with my machine.

The HRC kit is a performance kit with a cam, right? I think I recall reading something about an HRC kit somewhere but am unsure.

Does this kit greatly jeopardize engine reliability? I mean, I know that adding horsepower always decreases engine durability, but does this kit really stress the motor out to where durability becomes a huge concern?

From what I hear about those YFZ-450 motors, is that folks claim that they are so high-strung from the factory, that durability is a huge concern with them even when they are completely stock. So does anyone know if the HRC kit brings the Honda motor up near its breaking-point?

Reading about those YFZ-450 engines has me really concerned about blowing up engines. I want performance, but at the same time I really like reliability. If this kit brings both, and without frequent engine failure to worry about, that would be great news. Thanks.

if you get an 06+ then HRC kit and go.
if you get an 04-05 then hrc kit and a 12.5:1 piston and go.
both setups have plenty of power for the average rider
and both are extremely reliable if you change the oil regularly.

Edit ^^ What he said too... I must be a really slow typer!

The HRC kit is certainly the best bang for your buck (and yes it includes a cam, also larger headpipe (06+ only), jets/needle for carb, cut lid for airbox (04/05 only), subharness that changes ignition mapping and ups RPM by 1K (06+ only), larger diameter tailpipe insert, and a bung for the air box resonator. It's not an all out balls to the wall kit.. but it does make a good, noticable difference to the quad, but not at the expense of reliabilty. All for about $300.

besides the money factor...
do you think the hrc kit would be more reliable with a head port?? that way you gain a bunch of hp and still keep everything oem?

getting the head ported is also a very reliable upgrade assuming the porter dosn't leave any area too thin. but with more power come more wear.

AN HRC kit with a ported head or even a non Honda cam with a head port will be a great addition. ALthough more power means more wear it is in my opinion not measureable as you would have a failure in normal circumstances before a time when you need to replace the top end anyways.

^^^thats what I was thinking. Even though it's more hp and heat. It's just like a bigger intake and exhaust in the end. You are still going to have all the Honda parts with the legendary reliability

you dont even need to worry about wether they are Honda parts. There are aftermarket manufactures whom some make the parts for Honda for example the HRC header, HRC cam, I know DR. D made GYTR pipes for Yamaha for awhile and Works connection body protection.

many aftermarket companies make equal quality parts as the manufactures

You definitely won't have any reliability issues with an HRC kit regardless of the year of the quad. I have alot of mods done to my 07 and it never gives me any problems, nor does it run hot.
