Hey there fellow TT'ers, I have a conundrum that I'm hoping you can all help me with. I'm hoping to buy a new bike in the next few months, and am having a hell of a time deciding. I do know for sure it will be a Yamaha, but can't decide between 3 of them. I'll give you a bit of flavor for my experience, and riding style- I'm 31, 5'-9" and 170 lbs (without gear) and have been riding dirt bikes/ street bike off and on since I was 9. About 3 years ago I got back into dirt biking, and bought a 2005 DR-Z400, but quickly found it too heavy, and very undersuspended, although I found the power okay after a full pipe/ rejet. I sold the DR-Z and bought a pristine 01 YZ125 which I like a lot as it is light, and jumps well, but I just feel like at my weight/ skill level I'm just rat bagging it almost everywhere I go. I would say I'm a fairly aggressive trail rider (tight trails, logging roads, hill climbs, and lots of jumps...) I'm not afraid of doing my own work on a bike, but have never worked on 4-stroke...two strokes no problem, and that's why I'm considering another 2 stroke. Where I ride requires a bike to have a spark arrestor, and a head light, but I don't have a head light, and the park rangers never give me a hard time. Can you guys weigh in on the pros/ cons of each bike please, and no "that bike sucks, get a #### bike instead". I appreciate any opinions/ help.

Thanks.

Because of your comments on the DRZ and since you say that you are fairly aggressive I would eliminate the WR.

You seem to like the 2 stroke 125 and since at some point they might start enforcing a light I would suggest the YZ250 as the 450's are very difficult, i.e., expensive, to light up.

+1 for YZ240 smoker.
For trail riding, there are many mods to make them woods-weapons.l Some fast GNCC cross-country guys ride modded 250 mx'rs because they're light AND powerful.;-)

I'm not too worried about the headlight, as the rule is it has to be visible at 50ft away. The spark arrestor is what they really look for, as well as plate/ registration/ insurance, and that your not a knob (riding uncontrolably, drinking, etc...) I also ride a lot in my hometown in B.C. and the only rule there is you must wear a helmet. The reason I'm thinking 4 stroke is that I really liked the torque of my DR-Z...just not the weight/ suspension.

Maybe an sx/exc 300 or bored out YZ250? 300cc smokers have pretty good torque.

Then definitely go with the YZ450 for max torque and power! I have a smoker (200 KTM) but also need a track bike so I just bought a used '08 450 and I can tell you it's got the Power!:thumbsup:

If I got a 08/09 450 new, and was super meticulous with maintanence (which I am...it's a running joke with my friends that I maintain more then ride) and trail rode it, what am I looking at for valve/ top end life?

The YZ's are very durable . . . I'd say you should get 5 years out of all that stuff. I just sold my YZ400F that I bought new in '99, and did ONE valve adjustment, that's all. It was rock-solid, ran very strong when I sold it a couple months ago.
(I'll admit though that I didn't have a lot of time on it for a '99 . . . maybe 4 years worth or so)

I like the sounds of that! I talk to the dealers, and they are like "it's a race bike, and you'll have to do a complete overhaul at least once a year" I know they just want to get me to buy shit, so that's why I come here. Coming from a 125, do you think the 450 would be a handfull for me? I've ridden a tonne of 250 2-strokes, so I'm not a puss or anything...

the 450 have controllable power.
somtimes they feel like a tank compare to a 250.

suggest you to try 1 before.
its a love or hate thing.

Fabulous, you will probably LOVE the torque of the mighty 450, especially with all those mountains in your area!

We often go to the San Juan mtns of SW Colorado, and my tourquey YZ400F made a great "mountain climber." Can't wait to ride my 450F there!

Maybe your dealer is talking about an expert-level MX'r who rides the crap out of his bike . . . ANYTHING would be worn out quickly from that.

The newer WR is a great bike with a fork spring change and will meet your needs and requirements.I think the YZ 450 might be too much, but i guess the mags say they're mellower now.Personally I love my 05 YZ 250,FMF gnarly pipe,V force reeds, and a 9 oz flywheel allow me to rip around or putt around with much less weight even with a big 3 gal tank.A YZ 2smoke will probably need the least mods for aggressive woods riding.

I'm just concerned that the WR is way too heavy, and will not be adequate for jumps I want to do without serious suspension work. I want something I can slap a skid plate, and hand guards...maybe go a couple teeth up on the rear sprocket, and just ride. That's what I did to my YZ125, and it works fine other then being underpowered.

I would love to try one, but don't know anyone who has one, and the dealers would laugh if I asked to try one out. Everyone around these parts rides CRF's.

...also, how hard is it really to rebuild these 4 strokes? I find that I can take my whole YZ apart, and it's like a toy...no problem. I know there are more parts in the 4 stroke, and takes longer, but really, is it that much harder to understand/ do with a manual?

I have had both , the 450 and the yz250. The 450 IMO is much more versatial machine. You can take the thing to a track or you can throw hand gaurds on it and take it to the trails. The 450 to me seems much easier to ride than the 2-stroke because of the power curve of the bikes. The four stroke seems to just like to be left in gear and ridden where as the 2-stroke seems to want you to be on top of your game when you ride it.Maintence wise just change the oil and the filter and check valves every once in a while and thats it. Rebiulding wise if you can take the 2-stroke apart you can rebuild a 4-stroke , just a little more parts. Look over the manual that comes with it and you should be golden.Yamahas are known for there durability and the bike seems easy to ride . Hope this helps. Good luck:thumbsup:

no, four strokes aren't hard to work on once you understand them. manuals help a lot for sure. though some of the work done on them will be more in depth than a 2-stroke, it will be done far less often. its all in routine maintenance. valve clearance checks, frequent oil changes etc... these yamis will run forever when taken care of.

I have had a drz-400e in the past and it was way to heavy, I upgraded to my 07 yz450f and its insane compared to the dr-z. For the terrain we are riding out here you have to regear or ride crazy, Im regearing my bike this year to a 52 rear spocket and have added all the armor needed for the rocks. I assume you ride Mclean etc and the riding out here needs at least a 51 ot 52 tooth on a yz( unless your racing) if you like the control and tank ability that the dr-z had you have to regear. Trust me you will like the 450!! Oh pro moto billet makes a end cap for for the yz and it has a spark arrestor, easy install, I have one on my bike.
