450R or 450X?????

[jbltz450]

For XC racing should I buy the 450X or the 450R and put the narrow a-arms? Are the GNCC Pros running the R or the X?

[rdstoner]

if i were you i would go with the x seems how the x is geared a little diffrent from the r to give it a little more bottom end wich is real nice.

[250raptor]

doesnt really matter, they are the same bike besides a arms and axle. I went with the r and put a arms and narrowed it up

[jbltz450]

thanks for the input guys, do you mind post some pics of yours

[250raptor]

heres my yfz450r i built for xc. I've added a couple things since these pics but dont have any recent ones.

Standard.

But IF you insist, get the X. Narrower, Caster is -2 from the R, Mapping is different as well.

[250raptor]

No the caster is not changed on the x

[jbltz450]

250raptor, where do you live and what class do you race in the ATVCCS? your yfz looks sick!!

right the castor is the same. So if you are going to put different a-arms on it just buy whichever is the better deal. I would probley get the xc if they are the same price and run stock arms for a while. or if you mx occasionally get the R and you can put the stock a-arms back on for mx. not sure about the axle though

[quadrider2112]

R comes long travel so if you already have lt shocks on your old bike you can jus slap em on. X has shorter shock

yeah but the a-arms are still to wide for xc. He would need to get long travel xc arms anyway

Get whatever you can get cheaper. I bought the r and saved around 1500. Most people will change the a arms and front shocks. I bought gt thunder a arms with caster brackets and hls front shocks.

what did you do to narrow up the back? changed the axle?

I sent my rear hubs to gt thunder and gt thunder milled them. Laz included a spacer and than I inverted the studs on the hubs.

[jbltz450]

I havn't raced any in a couple of years. I used to race the pro-class in atvccs. #66 Chris Robinson, 2005 was the last time I raced the whole series and I finished 2nd overall that year. Since then I raced a few races each year but just havn't had the time to get back in it full time. My wife Miranda also raced the atvccs. I still have my LTZ400 but have been thinking real hard about the new yfz.

[02bwraptor]

Get the new yfzr/x. You will like it a lot. Back in 2005 I raced a 2002 raptor 660. Than in feb 2006 i bought a 2004 yfz. I bought the 2009 yfz450r last year and love the way it handles compared to the 04 yfz450. You might look at torn. That is what I am racing this year. www.tornracing.com

i had him mill mine also but he did not send a spacer and i havent inverted them, but my rear is wider than my back. does this narrow it even more?

cool, I just started halfway through last year on my raptor 250 and just moved up to the 450. You should get the new yfz and come out for some races. Next one is August 29th at Caddo Point

[jbltz450]

I am going to try to make some of the ones later in the season, I am working on the oil spill in the gulf right now and don't have much time off. Where in the hill country do you live?

[250raptor]

I live in spicewood. About 20 minutes from marble falls. Where is nederlands Texas?

My front is around 1/4 inch per side wider than the rear end.

[02bwraptor]

Both of you have a long drive to most of the atvccs races.

hmm, he didnt send me a spacer or anything, my rear is wider by an inch or two.

I will send a pic tonight if you want me too.

[250raptor]

if you dont mine that would be great. thanks!

[jbltz450]

nederland is 60 miles east of houston, close to louisiana border south of I-10

rear hub

[02bwraptor]

Hey jbltz450

I hope you don't mind me posting pics in your thread.

The spacer is the rusted looking piece.

[250raptor]

when you inverted your hubs how did you remove and press the bolts back in? just with a hammer? thanks for the pics

[02bwraptor]

Removed them with a vise and a socket. Pressed them in just with tightening the nut.

Chris, hey man this is Jeff Hahne (Josh's Dad) it's good to see your still around. How is Miranda these days? It was her wrist that she messed up wasn't it? Josh broke the navicular (sp) bone in his wrist and ended up missing an entire year with surgery and all. Then he missed another season finishing up college. He graduated and has been racing some this season. It would be neat to see you and Miranda at a race.

You too, Todd maybe you can make one of the ATVCCS races during TORN's break. Your YFZ looks good, I bet the R makes a good quad. Are the TORN tracks much different than ours?

[02bwraptor]

Jeff

I was planning on going to the atvccs race in caddo point in august. I love the yfz450r a lot better than the 04 yfz I had. I just have to get comfident on it.

Torn races or more technical, shorter and not as wide open as atvccs's tracks. I like slower tracks a lot better.

Hope to see you and josh in august.

[jbltz450]

Hey Jeff, good to hear from you to. Miranda is doing fine, we have been riding some just not enough time for racing right now. I am working in Houma, La doing industrial hygene work on the oil spill. Working 3 weeks on 1 week off. Miranda did break her right wrist at the atvccs race in alto back in 2006. However she broke her left wrist (navicular bone) back in 2004 at a MX national in Macon, GA. I went to the first round of the 09 atvccs season at Caddo Point and race my polaris 850 in the utility class. It didn't go to well as I wrecked it on the first lap and broke my throttle lever clean off. I was riding that utility bike way to hard and those things sure are heavy when you flip one over on yourself. Hopefully we will make one or two races toward the end of the year.
Talk to you later

[monster400ex]

i did the opposite i put honda 400ex hubs on my 450x makes it just as wide as the r

[250raptor]

woops guess i was wrong. hmm kinda wierd though, I was told multiple times they were the same. but good to know

[Soldier 425]

Ok, this is my reasoning behind getting an r over an x for the woods. First off, if you can get an 09 450r for $2500 off an 2010 x, I believe its better to get the r. People say the the efi is a little bit different so you can blip the throttle, well what is one off the first things you buy for an sport atv, is an exhaust. Then you go to buy a power commander to use with the pipe so the quad runs right anyway, so that messes with your efi changing it from stock so that cancels that out. Now the serious racer then usually changes his a arms and makes the quad wide anyway so they can have long travel shocks for better handling. Well I don’t have the money to buy thousands of dollars worth of a arms and shocks, then u got to make the axel wider and everything. The r is only 48 inches. The 2 inches aren’t going to kill you over the x. Pros and everybody run wide quads anyway. Even when you change the offsets on the tires it makes the quad wider. Personally I think on a hare scramble you make most of your passes on the mx portion off the track and being very fit to run 2 hours all out for the win. But it is just my idea and reasoning behind getting an r over an x.

The frame is exactly the same! The a-arms are different and maybe the spindles which give them the different specs but they still didn't fix the problem and handle bad for xc the castor changes durning suspension travel the opposite dirrection you would want it for good handling.

The problem is the a-arm mounts top and bottom are not the same distance front and back. They didn't want to make a new frame so they used the same one and changed the initial castor angle and put longer a-arms on the X so that the castor doesn't change as fast but it still handles bad.

It is an easy fix though you just need to buy a castor braket which requires aftermarket different size a-arms.

So like everyone said it doesn't matter which one you get to make it handle decent you will need to buy new a-arms anyway and that is pretty much the only difference between them.

finally someone knows what they are talking about.

[jbltz450]

thanks for explaining it, maybe I will just finish my full laeger 250r build and race it in the woods since I don't make that many races anyway.

[atvextremerider]

the only difference between the x and r is how wide they are for GNCC racing get the x

[zukirder93]

awesome quad, i was thinkin about getting a 2009 R stock width and I race XC as well. How does the EFI do on the starts? Im assuming until i get the money for some offset rims i can turn the stock ones around to make it a little narrower?

[coryatver]

it starts a lot slower than carb quads. flipping the wheels will make it wider not narrower and will make it have bad bump steer.

[zukirder93]

how much do the spacers cost a piece and do u need them for all 4 hubs or just the rear two. also did u use any lock tite when putting the studs back in?
