Kx250f 17’ or a ktm sxf250 15’

The kxf has 147h but has brand new tires on and a brand new cylinder and piston. It is being sold by a company. Also has new tires and no huge visible damages some scratches but not a whole lot. The suspension has been adjusted. They can also keep the bike over the winter and I pick it up when I want to start riding for no extra cost.

The ktm has 88h and is being sold privately. It had new piston and timing chain (kamkedja) at 78h has the recipt. It has a small hole on the seat cover. Some scratches on the plastics a bit more then the kxf. The tires have 4h old mousse. And the suspension was done 5h ago.

The upside with the ktm is that it is electric start. Wasn’t planning on doing a lot of enduro but some. But it is about 3h away. The kxf is a newer model but with a kickstart and it is only 1.5h away and sold by a company. Both bikes are listed to being often maintained. The ktm with oil change every 5-7h and the oil filter. The air filter after every ride.

I am planning on riding mostly track but some enduro. And I am a beginner so not going to riding it so hard.

They are both priced the same at about 3300dollar with zero negotiation. With the ktm I also get a few air filters with ktm.

So my wondering is what would you choose and how long would the bike last before needing a top rebuild or a bottom rebuild. I am planning on changing the airfilter after every ride and oil and oil filter every 5-7h.

I own a 2016 YZ 250X and I'm looking to convert it to more motocross suited, in other words to a stock YZ 250. The why I'm doing is that in Finland you can get a lot better and cheaper insurance for the 250X. This is the only reason why I'm not buying a stock YZ 250: strictly regulatory and legal reasons.

So, I've already got a 21"/19" wheel set and the suspension will be tuned to regular YZ 250 spec the next time I send it to service. I have the impression that the suspension is otherwise the same on both models expect the valving is different.

That leaves the engine. If I'm understood correctly, the difference is pretty much a wider gearbox, less compression head, different YPVS assy and CDI. I have to service the top end and crank bearings soon, so I'm opening the cases anyways. I'm riding well below C-class, so not that fast yet. But learning more every time I ride. I don't ride trails, only motocross tracks. Now comes the questions:

• I think the tracks in Finland are tight and somewhat technical compared to clips I see from worldwide. Does it make sense to convert the transmission to shorter YZ 250 spec or would I be okay just using different sprocket ratios?
• Would it make sense to do the top end conversion to higher compression? Does this only increase top RPM power and make the bike more twitchy, or will the power increase on the whole range?
• Will the YPVS conversion make the bike faster coming out of corners, or would I lose low end power and have to carry more speed to corners to keep the revs high?
• What is the difference between the "X" CDI and regular CDI? I got the impression that it's just a different timing.
• Would it make sense in my case just do the transmission conversion or just the top end & CDI?

What I am looking with these mods is to make my riding and learning easier. Sometimes at the track I feel that the current YZ250X setup takes a bit too long to get to the correct powerband and sometimes it feels that the 3rd gear is too tall and the 2nd gear too low.

I'm thinking of sourcing used parts for the gearbox, head and YPVS assy to keep the cost down.

I have a CR250 2001 and I ended up having my first major crash. Dislocating my shoulder and causing some damage to the bike. I ended up bending bars and mounts replaced both with new pro taper bars and mounts. Realigned forks and loosened and retighten the front end wheel clamps. Bars mounts seem still twisted. The left side mount seems to be the issues and bars aren’t straight any idea to fix. I can upload some photos later. Thank you for any help! Greatly appreciated!

I’m going to be near KL Sentral for a week and was wondering if there are any motocross tracks nearby that offer rental bikes. I’m looking for a place where I can enjoy some off-road riding during my stay. Any recommendations or tips would be greatly appreciated

So I have a 21 month old that both my girlfriend and I have decided we would like to get him involved in motocross at a young age. He absolutely loves his push-balance-bike and we are buying him an electric HiBoy balance bike for toddlers for Christmas. He's already fallen a few times and hit his face a couple despite having a regular helmet on. Are there any full face helmet out there for a toddles 22-24 months? I'm not really finding anything or any information. I know we're kind of early getting him started but any information would be helpful!

So, I own MXGP21 and find it great fun. But I wanted to buy amother motocross game.

I saw that Monster Energy Supercross 5 is on sale, on Xbox, for $4, I want to buy it, cus its dirt cheap, BUT wanted to ask you guys something first. Is it worth it to wait on a sale of Supercross 6 or buy MX vs ATV Legends Supercross 2024?

Would really appreciate any replies, thanks👍

Hey everybody I’m new to motocross’s am I’m thinking about getting a better seat cover but I’m not sure which one to get. Like do I get one with ripples in it or none or what brand to get. Any advice would be amazing and greatly appreciate. I have a 2025 crf250r.

I love what he has done for the sport and the guest he interviews, but I don’t care about your bike in Dubai, I don’t care what golf clubs you use or what life you have - I care about the riders information and opinions.

I know he needs to have a persona too, but I feel a lot of the times I can’t listen to it anymore because it’s too much😅

Change my mind.

I want to buy my friends CR that does not run. It blew up when he rode it with his buddy on the back, I am not sure what is exactly wrong with it without taking it apart. He wants $1000 for it but I’m leaning more towards $500. What do we think?

Does anyone know what line of sweatshirts this is from? I’m looking to buy one and I cannot find any. I know it’s early 2000s but I cannot find one and I would like to own this sweatshirt

I’ve tried on a pair of size 30 motocross pants that fit my waist but pretty tight. and too tight in the crotch area.

Looking to buy online so I’m wondering if sizing up would be best for more room and comfort in the crotch area while still fitting my waist.

Dont want to risk with a size 32 and have it be too tight also.

Im looking at a pair of size 34s, should that do the trick?

Does anyone here size up and if so by how much ? Thanks.

Im 35 and just moved to Vegas from SoCal. I need some riding buddies. Heading to Sandy Valley today.

I've got the e-moto itch. Never been on a real dirtbike. Just a sport quad back in the day. 35 170 lbs no track experience. Would I be idiotic to buy a varg as my first dirtbike? I'd likely keep it on 10 HP for a long time lol. I do have a Surron LBX thats fun to ride around town and on trails but at the end of the day its not enough for me

Edit to add I have a few tracks nearby so I would have plenty of spots to ride (not around town like my Surron)

I got my oldest a new yz85lw recently. He was riding a 2012 crf150f before that and had to race supermini. My question is, will he be allowed to race 85cc class with the 19/16 setup? Or will he only be able to race supermini unless we get a set of 17/14?

As I write this, im in a world of hurt. Seperated shoulder, cracked sternum, concussion, can barely walk or move, getting xrays of my spine today. I crashed, hard. But the more I think about the crash, the more frustrated I become. I hired a bike from a motocross rental company at Fox Raceway, Cali. Im visiting from Australia and always wanted to ride some Cali tracks. They supply bike and gear, you just show up.

This is my first time riding a dirtbike in over 10 years, but before that I had some decent experience.
I told the owner that im a heavier dude (100kg/ 220llbs). My fitness isnt great, but its not terrible, I ride a lot of MTB.

He had a lineup of bikes, and said this particular CRF450 was setup for heavier riders, so that would be my bike for the day. Did a few laps, first things I noticed was that I couldnt arch my foot back enough to reach the back brake, I would have to entirely take my foot off the peg. I also found that the smallest bumps (like hitting a small woop or rolling a table) would send a hard jar up my wrists. No where as near forgiving as I remember dirtbikes. I went back to the trailer, and asked if I could adjust the back brake to be lower. A younger guy working for him goes to clower the clutch. The owner corrects him and says "the foot brake" - the younger guy then goes to adjust the wrong bike. Anyway, I find out the last rider was really short so thats why the lever was high (im only 5 foot 6) I mentioned that it was killing my arms and wrists and the owner just laughed. I did a few more laps, the owner came and watched a filmed with his phone a little, and feeling better on the bike, clearing tables and doubles (which was a bit smoother on the arms), but the bar position/ lever height was annoying me.

I go back to trailer and grab a tbar and roll the bars forward, the bars were back a bit and the levers were pretty horizontal. I like to be forward/ over the front of the bike. A guy (who doesnt ride and does not know his way around a bike) who works with him said that the last person who rode the bike was a kid, so everything is still set up for a short dude.

I do a bit more riding, nearly every jump is just a hard hit up my arms though. I have a lunch brake, when I come back the owner says " take this bike for a spin" - is a '25 crf450. Man, that bike was a completely different bike is supension alone, I could finally complete a lap without my arms falling off. I rode back to the trailer and said this bike feels so much better, I just need to adjust the levers. The owner tells me im not adjusting the levers (they are way too high) as its his bike, and I dont know how to ride properly. I said the suspension is so much smoother/ more forgiving and he finally says "I will soften your bike back a few clicks"
Only to find out, its at its dead softest compression setting all round! The jarring I was getting was from the bike bottoming out. Im focusing on just trying to get used to riding again after 10 years off a bike, it didnt occur to me the slapping and jarr through my wrists was from it bottoming out constantly - I was told it was set up for heavier riders. The owner stiffened the suspension by a few clicks and said "take that for a spin".

I go out, and overjump a table top a bit. It wasnt that high of a table (more a long jump than high), and I pull up a bit as I land and give her some revs, and grip the bike - I honestly wasnt that worried about it. But the second I land my hands blow off the bars and im thrown off the bike. I rag dolled and bike cartwheeled (cudos to fox racewat medics - they are awesome)
I cant help to think that had the suspension been set to my weight, or even if I was on the other bike, I wouldnt of crashed in this instance.
In a lot of the POV footage you can see its hitting hard on the smallest whoops or rollers, with the shadow looking like its completely bottoming out.

POV of the crash here at 1:42, these were some of the better moments of the day before the crash. : https://youtu.be/jlbJl6BQb2k
Some (owner sent way more, but I dont agree with them all) photos of the damage : https://www.instagram.com/p/DCsRvLmSOSi/?utm_source=ig_web_copy_link&igsh=MzRlODBiNWFlZA==

He is asking me to pay to replace a lot of stuff. He sent photos of the torn seat (this was ripped like this before I even sat on the bike, I thankfully have proof of this), the exhuast (which was already heavily dented on the side), the rear rim (I dont believe I put that flat spot there. A rear wheel is stronger than that and I have screengrabs of what looks to be a flatspot already in the rear rim)

I havent got a full list yet but he is sending photos of scratches on plastics/ graphics on the bike. This bike was already well worn and abused.

Also, in a message from the owner, verbatim: "My buddy said you looked like Evil kanival way over hump with loop out Did look good but you got up"
I dont know how to take that - im in serious pain. 1, I didnt loop out, and 2, it looked good? But I got up? like what the hell?

Anyway, I would appreciate anyones thoughts on this - Im seriously thinking about pushing back against some of these repairs?
