Thanks,

I just bought the yfz450r front brakes for my 400ex spindles and they work awesome.. bolt right up and they outperform my 250r brakes all day.. I bought the hole setup calipers, braided lines, and master and lever for $50 shipped so you can probably find them cheaper than even just the adapters.. maybe you already know all of this but I thought maybe it could help you.

Will,
Thanks and no had no idea? Any year?? You are using 400EX Spindles, hubs and rotor?
Again,
Thanks
Doc

Will- Are you using YFZ-R or YFZ calipers? Or are they the same? I know for 100% certain the YFZ calipers will work on 400EX spindles because that's what I'm running.

My hybrid had 400EX spindles with adapters and 250R calipers on it, and one caliper went bad. I kicked around putting the TRX450R spindles and all on but that would be a very expensive set up. Then I was told that YFZ calipers will work with no mods. So I picked up a set and have been running them ever since. Bolt right up with no mods and work great.

I'm pretty sure it's the 04 and later yfz450r brakes. The other yfz450 only has single piston calipers and probably aren't much better than 400ex.
Yes, I'm using 400ex hubs and spindles. Everything bolts right up with No modification.

From what I have heard the yfz -r has the best brakes available.. my friend was doing stoppies on mine after I installed them, so I guess I believe it. I don't have the balls for that stuff lol.

The YFZ-R didn't come out until '09. The YFZ came out in '04 and had dual piston calipers on the front from the get go. The '04-'05 had a single piston rear caliper, but even it was upgraded to a dual piston starting in '06. I got my '04 YFZ in august of 2003 and spent a LOT of time on the YFZcentral forums learning all I could about them so I'm pretty sure that's how it is. I do know that my hybrid with 400EX spindles has the calipers from an '05 YFZ on it.

[hartwill]

This may be better answered by yfz and 400ex guys then. I don't even know what year mine are from for sure but I would say Yamaha's spindles for the yfz450s are probably all the same to save money, or at least where the brakes mount. I just ordered mine and threw them on, never paid attention to what year they were from.

Here's a thread from the 400ex section. I also read that the raptor 700 has the same brakes so maybe you can broaden your search.

I KNOW all year YFZ spindles and calipers are the same...all I'm wondering if the YFZ-R has different spindles and calipers. I'm thinking it does.

[brokenmike]

Any year raptor calipers work too

[89trx250r]

Gtilley is correct you need standard YFZ calipers the YFZR is an entirely different machine...

Even the old style Raptor? I know whenever they went to FI on the Raptor ('06 I think) that the entire front end was the same as the YFZ.

[hartwill]

So pretty much any of the yfz450 calipers before 09 will work? I know the other yfz uses just single caliper brakes I think it's the yfz450x. But I could have swore mine came from a 2009. Maybe I'm imagining things. But you are saying before 2009 it was just called the yfz450?

[gtilley45]

From '04 until '08 they were YFZs. It was a steel framed, carburated, 46 inch wide quad. Then in '09 Yamaha came out with the YFZ-R which was an aluminum framed, fuel injected, 48" or so wide supposedly "race ready" (yeah right) quad. I'm not positive, but they might have still been offering the YFZ, I know they still sell them, but they have cheaper shocks and stuff on them because the YFZ-R (and now also YFZ-X) is supposed to be their top of the line race quad.

I can't remember any year that the YFZ had single piston front calipers. I had one of the very first YFZs (according to the serial numbers, it was #109 off the assembly line) anybody in the southeast had seen and it had dual piston brakes up front. Both the '04 and '05s had single piston rears, but even the rears got dual piston starting on the '06s. Anyway....from the first year of '04s until the newer YFZ-R came out...the spindle/front calipers were the same.

I was as much of a YFZ guy as there was until the YFZ-R (and later YFZ-X) came out. I just didn't care for the aluminum frame, FI and I didn't think they looked as good as the older YFZ like I had. Plus the first couple years they were out, they were notorious for not making a whole lot of power. But from what I'm seeing, Chad Weinen and his crew have figured out that issue on the YFZ-R.

[hartwill]

I see, the one with the single piston calipers is the yfz-x I think that's the cheaper one that's a little narrower with a little different a arms and shocks. Anyway, next time you go to a yamabomb dealership check them out. There's actually quite a few differences between the r and x.. I then the x is also almost $2000 cheaper but I may be wrong.

[gtilley45]

Pfft, the odds of any of the dealers around here having both in stock is very slim. LOL

I knew the YFZ-X was narrower than the R but are there more differences? I thought the YFZ-R was like their motocross quad and the YFZ-X was the cross country quad. But like I said....I didn't spend all my spare time learning about those like I did the YFZs back when I had one. LOL

[89trx250r]

In regards to getting power from the yfzr motor...I'm sure Ryan Cox could get national winning power from any motor the guy knows his stuff and with Chad as his rider I'm sure they will go far :)

[gtilley45]

I agree.

[gtilley45]

Will- I hope you didn't think I was being one of those know-it-all *********s...I really didn't mean it that way. I was just reading back through all the posts and though "damn, I bet he thinks I'm a d!ck". Sorry about that. :D

This is the same Will that almost bought the a-arms I had isn't it?
