I have the opportunity to get an incredible deal on a brand new 2001 YZ 426F - about $1,200 below list !!!!

I recently took a spin on one and fell completely in love with the powerband. However, I keep hearing that it's too much bike for trail riding or enduros. I do mostly desert style enduros but there's some tight stuff in there from time to time. I feel that the responsive powerband and the 3-stroke like power of the bike would actually be a benefit in gnarly trails, and the bike only weighs a few pounds more than my XR 250.

I'm pretty much a novice rider at 5'11" and 165 lbs.

What are your experiences with this bike in the woods or in enduros ?

I can get a fairly quiet spark arrestor end cap for pretty cheap and would add a flywheel weight and gear it down.

To buy this is a bit of a whim but the price is incredible - I just wonder whether or not I'll wind up like a lot of the other YZ 426F owners who sell the bike shortly after buying it 'cause they felt it was too powerful or couldn't get the hang of starting it.

What does everyone think ?

Great price if it is "new". I have been riding one since March. LOVE IT. I ride both track and woods. I have geared mine down (13T front instead of 14T stock front)....equivalent to 3+ teeth off the back sprocket, and far less expensive. Probably my best mod. I have not added a flywheel, but have found stalling less of a problem as RPM's typically run higher w/ smaller sprocket.

Starting is your main hurdle. Learn this process ASAP. I had problems at first (45 minutes first time at track). Since I studied and experimented and learned....never had a problem, hot or cold starts.

Add bars to your list. The factory Yamaha bars are butter. Renthals solve that problem. You can wreck a da of riding really quick if you bend 'em.... as you know.

Power: Awesome. Are your in the tight Eastern woods? I am in Colorado where the woods exist but are less dense. The bike is great. To me, power=confidence.

Good luck.

BSDUPEE - the bike is BRAND NEW !!! The dealer has three he is trying to get off the floor. I ride in Southern California so alot of it is pretty wide open.

The things you had to say are helpful and encouraging.

Given your riding conditions, etc. you should go for it.

The suggested modifications make should work well; you mainly need some help to keep the bike from stalling in very tight situations (especially compared to the XR's ability to avoid stalling). You'll love the powerband in your conditions.

Starting. I suggest you go to Dirt Bike's website. I think they still have an article posted that discussed starting methods as discussed by Mike Kiedrowski, Randy Hawkins, Scott Summers and Shane Watts (its from an early 2001 issue). That article really helped me to better understand the starting drill rather than simply memorizing the drill. This helps you troubleshoot when things do not work. I'm on my second YZF and I now never have a starting problem. My previous areas of difficulty -

1. Learning not to start just after oiling the air filter.
2. Both bikes were delivered with slightly lean jetting. In cooler weather, the normal cold start drill would often not work and I would eventually flood the bike. I was extremely frustrated until I read Summers comments in the above-noted article and realized my bike wasn't getting sufficient fuel. Instead of twisting throttle 1-2 times, it required 3-4 times until the jetting was adjusted! Given all the published warnings about twisting the YZF throttle, I never would have tried that solution on my own.

You'll at least have a good head start given your experience with the XR. But you'll need to understand the effects of the pumper carb, hot start button, and manual compression release. The various methods / bikes in the DB article helped me piece it together.

Your concerns about turning in the tight stuff are warranted.
My Wr was a boat when I first rode it.
This is cureable.
I put a 52 tooth rear sprocket on it with the stock length chain, this allowed me to run the wheel all the way forward.
I also jerked the fork tubes up 10mm, this has made the bike a little nervous, but I like the tight stuff.
These changes have aided tight negotiations considerably.(THANKS MX TUNER!!!)
I also see that Scotts makes some different offset Triple clamps that I am considering in conjunction with a stabilizer.
I would jump on a yz-f for the right #'s.
I paid full pop for my WR and don't regret it or the 2k I have hung on it so far. I would still rather have this bike than any other available four stroke.

YZ426F

I only completed 1 mile of the last (first for me) TWMC enduro, so I don't really know what kind of terrain they throw at you, but I'll do my best here.

The YZ426F has a very high first and second gear (optimzed for moto), but you can still tackle most trails with the stock gearing. The only exception may be tight, uphill boulder gardens. Going one tooth down on the countershaft is a big help for the real nasty stuff and should still give a top speed of just over 80 mph.

I've been searching for the WR426 gear ratios so I could do a comparison of the overall gearing (stock WR426 first gear vs YZ426 first gear with one tooth smaller countershaft), but I couldn't find this much detail on the Yamaha website. Anyone have the WR426 gear ratio specs?

Four strokes aren't particularly strong in sand whoops (heavy on the front), but the 426 should blast through them easier than an XR250 (more power, less flex in forks).

As far as starting goes, the 426 is a easy starter in normal situations, but if you stall and tip it over on a tight trail, you'll have to go through the hot start routine. I use the hot start about twice a year.

426's flatten big hills (as long as they're not too technical).

Quite a few two stroke riders got the 426 and traded it right away because they couldn't get the hang of it - others kept it (even though they couldn't ride it at first). After about three months, the ones that hung in there really liked it, have had improved moto results and have come over to the Dark Side. I don't know that many enduro riders, so I can't speak for that part of the sport. I can say that my moto results improved dramatically when I got the 426, but I still suck at anything offroad (including GP's).

Those E-start KTM four strokes look tempting, but the price.......:think

Thanks Holeshot -

by the way, Thumpertalk.com has a great YZ 426 forum. I have seen the gear ratios listed in that forum ... you can search it for "ratios" and I know it's in there.

It's a beautiful bike and I am very, very tempted to go down and pick it up. I'm gonna wait for a few more responses and then make the decision.

By the way, you're going to be at Big Bear, right ? Maybe you'd let me take yours for a spin ?

:p

If you wen't from a 14 to a 13 counter sprocket it is equal to adding 3 teeth on your rear.

Eel,
I have a '99 YZ400 and ride exclusively woods and race enduros. I have changed the gearing to 13 -50 with 12oz. flywheel weight to make the bike managable in the tight stuff. The bike was very difficult to ride in woods with stock gearing and no weight (lots of clutch fanning). The 426 has even a taller first gear. Changing your gearing will take a significant amount from the top end. I am not so sure about the aforementioned 80 mph. If you like sustained high speed riding I think you will have a problem trying to make the bike work for both tight stuff and desert. With the money your saving you could consider swapping out for WR gearing. It has been done. I am not trying to talk you out of it, I love the bike for enduros but I am on the east-coast with tight woods, rocks and sand and rarely need the top end. BTW, you could still probably find a 2000WR on the floor on the east coast. I know my dealer had one as of a month ago (Pete's cycle Baltimore, MD).
Good Luck, Keith.

Eel, sounds like a really good deal on an awesome bike. I just recently picked up a used 98 YZ400 and I love the bike. I'm about the same size as you and used to ride a KDX200 and the YZ400 is such an improvement. The power seems pretty broad and there's tons of it everywhere. The suspension is awesome, although it's a bit harsh in rocky, technical type woods riding with lots of roots. But not too bad and can be adjusted. My only complaint about the bike is how easily it stalls. Last week I took the bike up to place in CT (Thomaston Dam) for the first time and I stalled the bike twice going up a rocky, technical hill. I was going fast enough and the revs weren't too low, but the rear wheel hopped over a rock and stalled when it hit the ground, most likely because I wasn't really going very fast. But still, not the place I wanted to stall the bike going up a rocky hill. A flywheel will cure this though and that's going to be one of my future mods for the bike. Other than the stalling issue the bike's awesome, and I'd definetly reccomend taking that deal.

Gear - YZ – WR
1st – 24/13 – 29/12
2nd – 23/15 – 26/15
3rd – 23/18 – 21/16
4th – 24/22 – 21/20
5th – 20/21 – 21/25

This info is in the manual, this is for ’00, & ’01, before that the YZ ratios were different.

Re: I'm not too concerned with losing some top end since I don't do baja or hare scrambles. I'm doing desert enduros and trailriding so I don't really see that I'll need to ever go over 60 even !! Besides, I think the pucker factor of going 80 MPH on a dirt bike might be a bit much for me ...

I'm glad to hear everyone's digging the bikes. I figure I will be saving so much money that the flywheel weight, gearing change, and whatever else are really not as painful as they would be if I had to pay full price for the bike.

Any maintenance problems ? I had heard somewhere that these YZs were going thru top ends pretty rapidly ? Any truth to that ? Also, how's the clutch been holding up ?

OK - so the bike seems pretty great. Alot of the people I ride with keep telling me that the perfect bike for me is the WR 250F. Now I have never ridden the WR, but I magine it will have a powerband that you have to flog quite a bit more than the 426, and the 426 also has a better power to weight ratio. There is something I like about the 400cc range power. It comes on very strong early. I have used it to power around turns flat-track style, which I have trouble doing on my XR.

Do you 426 guys any feedback on this ? I know alot of people who would say I'm making a mistake by not getting the WR 250F or even the YZ 250F. But theres just something I really liked about that 426. I have the possibility to ride all these bikes I mentioned this coming weekend ... maybe that will be helpful.

The short version is that YZ first gear is only like 4% lower than second gear on the WR.

The WR gearbox would be nice on tight, steep stuff. I just spent a few days in some fairly tight woods on my YZ (Rampart Range, CO). I ran a 51 tooth rear and was happy, but I'm sure that tractor gearing would have spared my brakes and clutch a lot of use (and some abuse, brake pads are toast).

I have not ridden a 250F, but I’m on my second 426, the clutch problems should be over in the ’01 model, I never heard of any clutches breaking on the ’00, but they didn’t work very well, and my stock basket rubbed the cases slightly.

I’ve never had any engine trouble with either, although the tranny flew apart on my ’00.

For that price, you can buy the two-six, ride it, and easily sell it (esp. in CA) if you don’t like it at for close to what you paid.

Hick:

Thanks for posting the WR ratios. According to what I've worked out, I'd have to run 59/13 sprockets to come close to what the WR first gear ratio is, and that's assuming the WR comes stock with 49/14 sprockets and if it's even possible to put a 59 tooth rear sprocket on without modifying the chain guide. This would also bring the top speed down to around 67 mph. Of course, I'm doing this late at night - maybe someone could check out my numbers? :confused:

Eel:

I hope to make it to Big Bear, but I'm not sure yet. If I do, I'll just put on a 13 tooth and you can judge for yourself.

You may be ok since your on the west coast, but riding the big YZ in tight east woods is like putting a kick me sign on your number plate. If you take the YZ into rocky, tight, or slipery stuff, you will have to ride it fast because of the gearing. This could really be un-nerving. I played with the counter sprocket on my 99 WR 400 and found the 14 was to fast for really tight slipery woods. 12 T made 1 st gear worthless, 13 put it right on the money. The WR 400 or 426 sounds like the ideal bike for the West coast trail work. The problem with gearing the YZ down is it all ready has so much low end bark, it may be hard to manage with more advantage on the rear wheel. I know alot of WR 250 guys go to YZ timing, but are coming back to the WR timing after the gray wire mod, because they are spinning the back wheel to much in the trails. I have never herd of anyone putting the WR timing on the YZ, but see no reason it cant be done. If the YZ is a VERY good deal, get it, try to tame it. If it dose not work out, sell it for the same price you payed as was said above or work a trade for a WR.
Good luck!! :)

I imagine that you will have to flog it

Absolutly not true. Eel you meet me at the qualifier up at Gorman. You know, the big 6'4" guy on the 250F. Well let me tell you that yes when you rev it out you are rewarded with big power (for a 250 4 strk.) but it also has good bottom end and midrange, there is no weak point at all. Now I dont know how much bottom power your XR has but ive heard that the YZ doesnt quite match it, but it has enough for me and I weigh 260#. I was neck and neck for first in my class at the qualifier until I got the flat. It just so happens that the guy that won my class ( B 4strk. ) was on my minute and he was ridding a XR 650. I never felt at a disadvantage to him in the more open sections and could walk away from him in the tight stuff.

But the 426 is a nice bike also and for that price I would say go for it. I have a 99 400F also and for tight woods riding like at Gorman I would diffinetly recomend the gearing change and fly wheel, it makes switch backs with abrubt hill climbs right out off the turns much easier. I have never had a clutch problem with the 400, but the 250 seems to chatter alot. You would probably want the suspension set up for you on either bike, as they are not that plush off road stock. You just cant imagine what good suspension will do for you, its incredible how plush they can get the action and it still have better bottoming control than stock.

se you this weekend

Your calculation is accurate as far as I can tell. I can also tell you that letting out the clutch in first gear on a WR reminds me of driving a tractor, all the WR needs is a three point hitch to hook the plow up to.

But that kind of gearing is ridiculous in sand.

If you are serious about this I would think you could split the cases and change whatever gears you wanted to WR parts, but I have never tried or confirmed this.

Scar - thanx for the interest in the XR - since it's green I'm gonna keep it for the times I wouldn't be able to ride a red sticker bike ... by the way, I'm still up in the air about the big 'ol 4-2-6 ...

Hey the Eel, whats the dealers name and were are they. I'm in the mid west and I have been looking for that kind of deal. At that price I could have it shipped and still save.

I recently bought my first bike, a KTM 640 LC4. It's about the same size as the YZ, but much heavier.
I found that the power was pretty easy to get used to, just watch that you don't rev too high when the
clutch is in until you can control the power. As far as tight woods, the size of the bike makes it difficult.
Practice sliding your but off the seat so that you can put a quick and solid foot down if you have to.
It seems like the suspension sunk a little as I broke it in, which allows me to at least touch my heels down.
Currently, I'm staying away from tight situations until I'm a better rider. If you pick your trails carefully,
You should have no problems starting out. When racing, I guess you don't have a choice.

I'd have to say, if I had to sell it to get an off road only bike, I would get something small and nimble.
The size of the bike is great on the road, but off road I feel I'm limited by the lack of ability to man-handle
the bike. A small light bike may be more fun for you if you like catching air and hitting the woods.

When you look at the number of views on this thread (almost 700!) it's apparent that a lot of people have a keen interest in how the YZ426 performs in the woods and on the trail. I've been doing battle against these bikes in enduros for the past year and a half. My observation is in 80% of the conditions you just can't touch them. Their combination of weight vs. power is a tremendous advantage, especially if you are 6'+ and over 200 lbs. Granted, I have seen many a 400 or 426 on the side of the trail being frantically flogged in an effort to restart but I also see them winning a majority of my class races (Open, 4 stk). Their contingency program is something to think about also if you race. They even pay C class money. Every penny helps.

I decided about two months ago that "if you can't beat them, join them". My '02 YZ 426 is supposed to be here in late September.
