2 stroke 250 vs 4 stroke 450 for going slow in the woods?Which is better if you put a heavy flywheel?
>>28961573Cager but I thought 4 strokes caught up to 2 stroke power density by now
>>28961575Power wise they’re basically the same. 4 strikes just have a more predictable power band, and 2 strikes have a ton of bottom end torque.
>>28961573Electric dirt bike.
>>28961573Electrons are best for low speed, but a 2 smoke is the most fun overall. 4 strokes are a decent middle ground and the easiest to live with, tho.
>>28961586LOL
>>28961592They’ve gotten to the point where they win supercross races occasionally. They’re no longer a joke.
>>28961588I do like 2 smokes. I’ve been looking at a lot of bikes lately. I found a 2000 yz250. Guy wants 2750 for it. Condition looks great for the year.On the flip side I found a 2007 rmz450 for 2500. Guy has 5 hours on a complete rebuild and “stage 2 hot cams”. Condition is also good.If I’m being honest I’ve had 3 dirt bikes before. 2 and 4 strokes. I thought about getting a little dr350 for putting around but there’s just something about the power that keeps me coming back to dirt bikes.
2's are better.No I won't elaborate, but I will mention how much lighter they are.
>>28961595I’ve got a 1997 CR250R and a 2021 CF300L. Riding the CR250R is an event in the positive and negative sense, but the CF300L is as easy to take out as my pickup, and ends up being what I ride most of the time.
>>28961573>going slow in the woods4 stroke obviously Have you never ridden a 2 stroke?If you dont rev the piss out of it youll foul a plug.
>>28961573Newer 4 strokes are all mapped for motocross and emissions meaning they flame out worse than old two strokes in slow technical stuff. you need to remap them, buy new sprockets, and even then they still won't tractor like an old carbureted drz or xr400 will from the factory. Newer 2 strokes are ironically excellent in slow stuff. Direct oil injection and adjustable ports combined with heavier flywheels means they don't really have the powerband issue. I rode a ktm exc300 and it had plenty of low end torque they've come a long way. New 300 2 strokes are the best woods bikes
>>28961633That makes a lot of sense. That’s kinda what I’m wondering about the 2 vs 4 stroke thing.I just remember the 250 having lower maintenance, but at the same time, do I really want my arms yanked every time I ride, you know? Haha
>>28961644To add onto this I wouldn't buy new of either if I was a new rider, get a 20 year old 4 stroke and crash it a hundred times before buying a $12k Husqvarna
>>28961644What do you think about this?>>28961595Say in comparison to these 2 bikes. Would the 2 smoke still be better?
>>28961652The yz you need to wring the shit out of it, they have 0 bottom end. Rmz is a classic modern 450 with no bottom end either. I had a childhood friend with a dr350 and they're pretty meh bikes, it will do fine in the woods but they're pretty gutless. Depending on how tall you are I would upgrade to a drz400 maybe xr400 if you're 6ft+ they are excellent woods bikes with enough power to never really get boring. Kdx 250 is also a great old 2 stroke and they're pretty cheap they tractor along really well
>>28961650> do I really want my arms yanked every time I ride, you know? HahaMy gut answer to this is “Yes” but ultimately the ability to ride for pennies without needing to wear ear plugs and ride to where I want to go instead of loading my CR into my truck won out. 100 miles between fills in the CF makes the sand roads and rail bed trails accessible without it being a whole production like my 30yo race bike.
>>28961644>New 300 2 strokes are the best woods bikesI don't know anything about off roading. What's the best desert bike?
>>28961858What are you doing in the desert? Depending on your answer, it could be a TW200 or a Stark or a race 2 or race 4 stroke.
>>28961868Hmm, let's say open desert hare scrambles with some mild technical sections. Or maybe just some weekend fun with big sandy(I'm not sure if the hills are sandy or rocky. I've only seen them in videos or from afar.) hill climbs.
>>28961595>Selling his bike right after going through a rebuildHmmmmmmmmm. I have some questions. And he hetter have recipts.
>>28961879any 450 is a good choice
I used to want a Yamaha TW200 : [ I am too poor for anything now and just wait to die
>>28961922Oh, okay. That makes sense. Thank you
>>28961912Oh yeah, thanks for bringing that up. I need to ask him about that.What questions would you ask, and what are red flags to look out for?
>>28961953Ask for every receipt. If he says he built it himself then walk away. Do not trust checking for glittery oil because chances are he changed it before listing. And bring a stethoscope (mechanic's, not doctor's). If you can, an endoscope will help you peek inside the cylinder. Anyone that takes offense to you crossing your Ts is full of shit.
>>28961953Also, the FIRST rule of buying things online is learning how to walk away.
>>28961996I appreciate that advice a lot anon. Thank you.>>28962002How do you say “no thanks I’m not interested.” I struggle with this, but I don’t wanna lie.The next time I post I will have dirt bike to show you guys.
>>28961996Oh yeah, and anon- I hope I’m not bothering you, but the guy with the YZ messaged me back. I’ll admit this is a little concerning to me. I had a KX250 that leaked transmission oil. Never again. What do you make of this? Is this a big deal if it’s not a lot?
Realistically speaking, is maintenance actually a lot higher on a 4 stroke than a 2 stroke?I was reading about people saying you have to check the valves, timing chain, change engine and transmission oil; whereas a 2 stroke you have to only worry about transmission oil. What’s the deal on that?
I have a question. So I thought of what I should be asking.I love the low end power of a 2s 250, and 4s 450s are cool as well. I just wounded if maybe neither are what I’m looking for.The torque is cool, but at the same time, I kind of feel like I’m riding a fast bike slow on each one.What are your thoughts and opinions on this? Should I go with a different size or completely different bike?I like the power; I just don’t want to feel like I’m going balls to the wall every time on ride.
>>28962042At least it will be easier to rebuild than a 4 stroke if you really want to go through all of that.>Only tells you it leaks but not whereI fucking hate it when people can't give any kind of detail so now you have to bombard him with questions. If it smokes a lot more than normal then it could be anything from an internal leak from the case gasket or the crank seals, I guess.>>28962038>How do you say “no thanks I’m not interested.”That's pretty much it. It is best to point out anything they kept secret from you as you check it out.
i just bought a 2007 kawasaki 250f.
>>28962965>is maintenance actually a lot higher on a 4 stroke than a 2 stroke?4 stroke is more nuanced maintenance, 2 strokes are more build, break, rebuild.
>>28963144Very nice, friend. Is it fun?
4t hands down.Happy riding my pigfat XR400 around the forest, the stinky, peaky 2t are just too busy all the time.Personal preference, but I can just drop a gear at any RPM and go WOT up a hill. The smokers have to make sure they hit the band and stay in it while they hold on.
Would you say it’s a dumb idea to get a 250 2s or 450 4s dirt bike if I want something with plenty of torque but also just wanna slow it down and take it easy but also would like to jump some hills?I feel like the bike I want doesn’t exist in a singular bike..
>>28961586This, sincerely. Electrics out range what almost everyone does with a dirt bike. The torque is instant and everywhere, and being quiet in the woods is kino,
>>28964788it'd be sick if we were like 50 years in the future and gas stations just had a standardized quick-charger setup, and you could park your bike up for a bit and go eat some food and it's fully charged by the time you're done with lunch and you can go back out and ride.
>>28961573>450 in the woodsLol no. Get a 350 or if you MUST have high displacement a 500, but not a 450
>>289629654 strokes it's just the engine oil, check valves occasionally
>>28961573I've been looking into dirt bikes again lately. I had a xr200r in high school that I beat the shit out of for years. Now I want to get one again. It seems for technical off road nothing beats the 250 and 300 2 strokes, but I think I've settled on a crf250f. It seems that if you spend around 3k in mods on stuff like a suspension lift, shock, etc, you can set it up to be a decent trail bike, while also being street legal. A 2 stroke would be better, but the 4 stroke seems to be more practical in the vast public lands of Arizona.>>28962965Back when I had the old honda 4 stroke all we did was change the oil regularly. Used it for years on almost a daily basis and never had any issues besides having to get a new carburetor one time. I know modern bikes may be more needy, but I doubt they're too much more involved.>>28964326Most bikes could be good enough to get the job done in most situations. Just get one and figure it out from there. Its not like these things depreciate in resale value. You are being to vague for a specific answer.
>>28964326That's a 300 2T, anon. Although more to the point is suspension and geometry, displacement and transmission are only a part of the puzzle. You may be looking for a cross-country bike (300 XC, TX300, 250 RX, that kind of thing)
>>28961573>going slow in the woods?>Which is better if you put a heavy flywheel?4joke 450 then, if it's about going fast then 2smoke easy for the p/w ratio advantage. 4joke is better for lower speed stuff because better low rpm tork
to all the anons who are asking about 450s, if you're a new rider or even a mediocre rider i would avoid them like the plague. The skill curve is very steep and actively prevents you from learning the foundations of riding something that powerful if you haven't gotten fast on a slow bike first. You would be better off even getting a 500, ye be warned
>>28964940I try to tell people this all the time, 450's are for racing and they're no good for anything else. Idk why they never listen
4 stroke is easier to ride and has substantially more power.But, 2 stroke is more fun and easier and cheaper to maintain.I prefer 2 stroke, I ride a yz125 in 250B against almost entirely 4 strokes, but I'm not trying to qualify for Loretta's, so who cares.
>>28961573Big 4 strokes have better low end but they have overheating issues at low speeds. Modern 2 strokes are a lot more usable on the low speed stuff. I'm just looking into getting into it but that's what I hear from my dirt biking buddies.
>>28961573Yeah for putting along you want a 4 stroke for the low end torque. 2 stroke is no good for enduro riding unless you're riding flat out.
>>28964940>>28964954>I try to tell people this all the time, 450's are for racing and they're no good for anything else. Idk why they never listenI’m currently leaning towards another 250 2 stroke. I’ve had 2 of them, and one crf450r.I’m curious on your take. Would you say to avoid 250 2 strokes if you don’t race too? I’m not gonna lie, the 250 2s, and 450 4s are both a lot of bike. Like I’ve said, I love the power and torque on both. I do feel like maybe the 450 has a lot more unusable power. Idk correct me if I’m wrong.I don’t race.>>28964980Yeah, I’m leaning towards a 2s because of reasons above plus maintenance cost.>>28964984I’m currently planning on going to get a 2001 rm250 next weekend. Couldn’t get anyone to go with me this weekend. Unfortunately I can’t afford a modern 2 stroke.
Most of this thread is riddled with bad advice from people who don’t do any serious enduro.First of all, if you’re going to ride technical enduro, get a bike suited for that role. No MX bike, no trail bike, and no big cross-country or fast enduro bike. So no 450 four-stroke.On 2-stroke vs. 4-stroke, it ultimately comes down to personal preference. 2-strokes have a significant advantage in flameout resistance, which is the main reason they’re generally preferred for technical enduro. They’re also easier to maintain and produce less heat. 4-strokes offer better fuel range, longer intervals between rebuilds, and a more linear power curve. Yamaha’s 4-strokes (and Yamaha-derived bikes such as Fantic) benefit from a nice 180° rotated architecture with better air filter placement and a protected exhaust.
>>28961586this nigga knows>>28961592You're the only one laughing.
>>28965273>no trail bikesAre you trying to say enduro bikes are no good for enduro? What are you calling a trail bike here
>>28965211You'll notice it most in the suspension. Race bikes are a lot stiffer which makes them rather unpleasant on slower trails. YZ250x's are quite popular around here, though, and they're supposed to have a much plusher suspension. Gearbox and power delivery you can learn to work around, but it's pretty importan tto get the right sudpension for your application
>>28964940I've met a couple guys in the wild with 450s and most of them had rekluse clutches, must be the only way to make them tolerable in the woods
>>28965318Yes I don't doubt it. I haven't seen anyone with a 450, and I'm the only one I've seen riding single track on a 500, but the rekluse makes a huge difference. I had to do a lot of suspension work to mine as well, but that's really just because the previous owner was twice my weight
Get the one that isnt carburated
>>28965273>no trail bikeunless you're trying to do the ezbergrodeo a 20 year old XR is more than capable. I've rode through some seriously sketchy stuff in idaho with guys on betas and guys on big 500 ktms. The only part that sucks is no electric start
