KTM 450SX-F Transmission Problems?

Recommended Posts

I have always been a kawi guy and have thought of going to ktm. Ktm every year has the sweetest looking bikes and i know tons of extemely fast guys on them. The question i have is about their transmissions. A guy i race with rides an 08 450SX-f. He is kind of an idiot so i don't know how much i believe him, hense the reason for this thread. He bought his 08 brand new last nov-dec and claims he has allready had to have the dealership put 2 transmissions in it. Another kid we race with also has a 250 and 450SX-F. I have not asked him about his bikes but this other guy says he has had tranny problems as well. I figured i would just ask guys that really know these bikes and see what you all have seen. For all i know this guy may be screwing something up with fluid changes or something. Any input would be great. Thanks Guys.

Never even heard about any tranny problems on 450/505 SXF. I´ve had both -07 &-08 bikes.

No problems with my '08 505 transmission other than every now and then I have a heck of a time finding neutral while it is running.

Four KTM's from 2001 to 2008. No transmission problems. Not heard of any either. Did have a Kawasaki 2004 KXF250F with Third gear sliding gear bearing go out first 10 hrs!

That's what you get for buying a bike with a POS Suzuki motor!:)

The RMZ/KXF 250s are not known to have the most reliable transmission. If I remember right, the Pro-Circuit team used a full works transmission in their bikes during these years because of reliability issues...

No problems with the tranny in my 08 450sx so far. Like eastreich said Its is tough to find neutral sometimes while it is running.

My XC505 hits false neutral between 2-3 and 3-4 quite a bit.

On any dirt bike I would not do that. if your going to stop and kill the engine stop and kill it, then find netural

If your going to stop and let it idle put it in neutral before you stop, your clutch will last a lot longer and your trans will be happier too!

The 450/505SXF 4 speed is a different style trans than the others, the most bullit proof trans KTM has built

'07 450SXF with 100 hours. No tranny problems.

However, I do know a guy who's son just to ride an '07 450SXF and had major tranny problems. That guy's kid rides in the intermediate level so he is much harder on the bike than I will ever be. I know they changed the tranny oil after every race. I think KTM took care of the tranny under warranty but it took months. The kid is on a Honda now.

08 450 SXF, 08 450 XCF, 08 250 SXF - all one year old and ridden often and no tranny issues to date. The con rod did go out on the 250 and KTM covered it under a recall warranty. On the second topend on the 250 due to dealer incompetence! No bike is bullet proof but the Katooms are tough for sure.

Or not... I never use the clutch for anything else than starting and when i lock the rear brake before a very tight corner. I have never had any tranny problems on any of my bikes.

Old wives tale. Smooth riders have no problems with clutchless shifting, the style of trans used in the SXF could care less.

I have been clutchless shifting for about two months now and as long as you're smooth with it and time your throttle as you do it things go very smoothly. It makes riding pretty easy, especially when standing. As far as trouble finding neutral I try to click into it as I am rolling up to stop, otherwise you sometimes have to roll the bike back and forth a bit to take the pressure off. Turning it off works easy too. As far as staring the 505 in gear it seems to work best when you remember to pull the hot start and no throttle. Usually when I am staring in gear is when I am in a hurry, I stalled on the trail and want to get moving before I get passed so I push the magic button and give it gas because I am trying to go. It can take a bit to start that way but if I remember to relax and lay off the gas, pull the hot start it fires right up even in gear.

Been clutchless shifting for 15 years now from way back on my KX60 days!! lol and never a problem with any of my bikes. :thumbsup: So lets just conclude that no bike is 100 percent bullet proof and just because one guy had a problem, doesn't mean all the SXFs will, no riding conditions/riding style/bike is exactly the same. Sometimes things happen, to all brands, and thats just a part of the game sometimes.

      Hello everyone, I am new to the page and to the world of ktm. I recently purchased a used 2008 ktm xcfw with a 300 big bore kit, not sure who made or installed the kit. I am looking to see if there is any way to buy a new carb that is set up for this bike with the 300 BB. Any help would be great. The fuel inlet is leaking and there are a ton of stripped screws so I’m thinking getting a new carb might be the best way to go but i don’t really have the skill or knowledge to tune and jet a stock one myself. Thank you!

      i am currently checking valve clearance on 2013 sxf 250 with 70 hrs. bike was bought new and never been apart(as far as i know). when setting TDC the notch on the crank when it is aligned to the whole, has the cam gear marks intake totally up and exhaust totally down. are these the wrong marks to look at or am i missing something. bike does run just a little difficult to start.

      Hey all. I’m a newbie here so let me know if  I’m in the wrong place. 
      I’ll get straight down to it. I’m in the market for a new bike and have been thinking about what’s going to be best for me for a long time. Until recently I finally came to the conclusion that a new YZ250FX is my best option. My last bike was 2015 Yz250f which I loved.
      Now just yesterday I saw a local dealer advertise left over 17’ FX350’s for almost the same price as the YZ. What appeals to me about the Husky is that extra grunt. What doesn’t appeal to me is the suspension and handling and the reliability of the machine. Now I’ve never owned a KTM or Husky so I am basing those two factors on word of mouth only. Like I said, I loved my Yz250f and felt very at home on it, it has probably been the best bike I’ve owned to date. Yamaha reliability is also second to none which adds to my peace of mind on purchasing the YZ. One thing I wish it had was more power though. Obviously it’s only a 250f so you can’t expect it to go like a 450 (not really interested in 450s).
      I ride mostly trails and the occasional day at the mx track. The trails I ride are gravel based, loose, rocky, single trail, and also wide, fast, flowing, sand trails which is where I think my yz250f really shined, and where I had the most fun. I’m only a small rider at 145lbs which is why I’ve steered away from 450s. 
      I’ve read a few forums and others have said the ktm and Husky 350s are unbeatable on the trail which is why I am in this dilemma.
      So basically what I’m trying to decide on is if that extra power is worth compromising for the YZ suspension, handling and usability. Feel free to make any other suggestions, including other bikes as I was also considering the YZ250X 2T.
      Thanks guys

      The story begins with simple installation procedure of a BIG BORE kit that we ordered from USA . The manufacturer (CYLINDER WORKS) and the dealer send us the correct kit and so far so good ! .
      The bike is a KTM 250 sx-f ,2011 model and bellow there are some photos for you, just to see how careful I am throughout the process .
      .. .. .. .. I change the valve seals and the exhaust titanium valves and springs with the PROX steel kit and make a little polishing on the intake and exhaust
      ......
      Put the cylinder-piston on and always with guidance from workshop manual and correct clamps...
      ..
      AND READY
      ...
      Until now we where happy !!! We start the engine ,and everything seems to be ok!
      Began to make the first ride and…… DISASTER !!!
      The engine start bleeding OIL from the hose-tube !!!!!!!!! I thought its normal if it is one-two drops but unfortunately didn’t STOP .
      We did one more ride to see what happens and still BLEEDING. Back to the WORKSHOP.
      DO YOU HAVE ANY SUGGESTIONS OF WHAT TO CHECK OR DO ???
