YZ450 in the woods or a WR45f on the track... which would adapt better?

20 posts in this topic

If you were to compare the performance of a YZ450 in the woods* with the performance of a WR450f on the track, which would adapt to the 'foreign habitat' better?

*By woods a mean fairly wide open trails( big enough to fit a 4x4 ATV) and dirt roads, not small single tracks.

I ask this because I want to experience both without feeling extremely gimped on one or the other terrains, and I'm having a rough time choosing what bike.

get the yz..i just got an 03 yz450 for open trails..its great..just make sure you won't be in 1st/2nd most of the time..if so..don't lean towards the yz..i haven't had "over heating" problems with my bike at all except when i went on a track for the first time and stayed in 1st/2nd..it spit lots of coolant out

YZ in the woods! My bike has never seen a track and I haven't even set the sag yet. I put in the heavy off road GYT-R flywheel and added a Dr. D spark arrested pipe, along with all the standards woods goodies (hand guards, rad braces, skid plate , etc.) and couldn't be happier. I also had a woods-ified 00 YZ 426F prior to my 06 YZ 450F and loved it also. The WR will not be happy on the track- all I'd have to do to my YZ to get it track ready is... well nothing :D Get the YZ, you won't regret it.

Hands down an easier path is to take the YZ and mod the chassis for woods. It's far easier to soften up a suspension for woods, than it is for you to firm up a soft suspension for MX. Trust me I been there trying to adapt my 2002 WR250F to do some club MX racing. The WR's simply are sprung and valved too soft. On your YZ, soften up the compression, and a flywheel weight, lower the gearing, and you should have a great woods bike!

I just got rid if an 06 WR450 and got an 04 YZ450, so I feel I have a good perspective on the question.I bought the WR for several reasons, smoking deal, never had a strait up woods bike, and wanted to plate it. I did the usaul list of things, performance mods, exhaust , damper , springs, handle bars...etc, all the stuff to make it "fit" me and my anatomy. I will say that the biggest difference is in the damping rates for the suspension and the gearbox. Being a wide ratio 5 speed I never felt like I didn't have a strong gear to pull. In addition with wider, smoother power spread it was really manageable in the tight slippery stuff. I rode 90% woods and 10% MX. It would handle the track just fine as long as I used some judgement. No big triples or flat landings. The WR had no problem running with the MX 450's in the power dept., where it suffered was in braking and change of direction. You really noticed the extra 30lbs that it carries over the YZ, but overall it was a great bike that did everything I asked it to.

My YZ is little more of a handful offroad. (Read stiff suspension, tall gearing, and harsher power delivery.) The other down side is that I no longer have the Magic Button to bring the bike back to life when I am stalled on a steep climb, no headlight to go night riding with, and no hope of plating it without the dropping of some serious cash for lighting equipment and new exhaust and tires. What I do like is that it is, as I said, ~30lbs lighter and you can feel it.

If you are trying to decide between the two, first ask yourself how you will ride it. Track more that woods? Any desire to plate it? How much bike do you want to lug around? Night rides? I think the YZ will be the more competitive rig for the all around effort, but are we all serious racers? No. Just figure out how you will ride it and I think it will be apparent which one to get.

Just my input.

I was considering selling my '04 and getting a WR and asked a similar question right here:

I'm a lot like you- open "woods", jeep trails, ATV. I really don't like single track that much as I like the option of changing lines. After reading the responses to my thread, I'm keeping the YZ and modifying it a little for the occasional off-road foray- skid plate , FWW, and lower gearing. None of this is going to hurt me on the natural terrain tracks I ride on, either.

Your best friend in the woods with any 450 will be "managable torque". You DON'T want to be fighting a race bred engine in the woods. Don't be afraid to throw in a nice heavy F/W weight to tame the bottom end and midrange (because this is the only parts of the torque curve you will be using). My '07 YZ goes trail riding ocassionally and I still wish the engine was a bit smoother down low (and everyone knows the '07 YZ450 is already a super smooth, and friendly engine.....)

My YZ is geared 2 teeth up in the rear, and I back off my compression 4 clicks and hit the woods, and it does a good job.....but it's still a tad stiff

Well put, at least you have a perspective... I've always had a YZ until the 07 WR's came out. I race desert and enjoy to do the GP's at Honeylake. The WR took some time and money to get to handle a MX course. It will never be close to a YZ on a MX course but it's my choice for the kind of riding most of "us" do. We did just finish Vegas to Reno on the WR, 30th oa and 1st in the over 30 expert class. If I had my way, I would be able to aford both. There both great bikes. Jeff S

A point to bear in mind is that the '07 WR is somewhat different than the earlier models.

I can't offer any input on the 450 YZ vs. WR, but when I had my WR250, a big issue when trying to shift gears aggresively was the wide ratio tranny. It was very hard to keep the rpm's up, especially in the softer loom and sand. (I almost split my 250's cases and swapped over to YZ ratios, thats how much I hated the WR tranny)This might not be such an issue with the bigger torquier 450's.

Regardless of which brand motorcycle, it's always easier to take an MX bike in the woods than a woods bike on the track. I say that after owning XR's, DRZ's and finally a YZ...it's the best "do it all" bike around IMO.

I've been changing a few things on my YZ to make it better in the tighter trails/woods, I like the power of the YZ better.
