    Amazing power, can lift the front wheel up in all gears. Expensive to maintain.

  16. I'm a huge KTM fan and love my 350 SXF but I'm considering abandoning ship for a '14 250 Sx. My bike is an 11 and only has around 5 hours on it. My wife and I have 5 kids and I just haven't been riding much. All the ever changing technology is awesome and really advancing our sport but is intimidating for guys like me to keep up with as far as mechanics go. And my 350 is kind of hard to ride with my boys who are on 50s because it just can't be ridden slow. I've raced MX for years but have slowed down since having kids. I have a boy who will be starting in the 50 class this year so I plan to race the series with him and I'm just not sure about going back to the 2 stroke. Has anyone here jumped ship back to one of the newer KTM 250 SX's? If so what are your thoughts, experiences, and recommendations? I love the ease of maintenance, light weight, and cost of maintenance of course but other than that I'm torn. What are your thoughts?
  17. Hello I dident see any sort of "show ur KTM" threads around here, and since KTMs are so beatiful, I decided to make one! So here it is! Show us your hardboiled rice killer
  18. hi TT users i have a flat 11 acre property 20 mins from my house. the property has a pond in the middle of it. i am wanting to build an mx track on there, What equipment/excavators will i need to hire. how will i go about constructing the berms, whoops, table tops and jumps. And how can i keep out unwanted riders. How much dirt will i need? i would be great if any ones knows track designers and cheap dirt and machine hires. (Dont have much $$ to spend so free or cheap dirt and equipment would be GREAT ) i am in Brisbane, qld, Australia. Any quarries i can phone to dump free dirt thanks
  19. I have a 2007 KTM 250 sx-f, I have owned the bike now for 6 years. I have never had an issue with the idle on it until last fall. I had a local shop work on it and now it is hard to start, and idles weird. i can get the bike warm adjust the idle, it seems fine then a little while later acts up again. Does anyone have a trick to setting up a proper idle. Due to my current location, I would need to drive an hour to a local KTM dealer, so I would rather try to figure this out myself. Thank you for your help in advance.
  20. I have a 2006 KTM 250 SXF. I just got it back from the shop, they put a brand new top end into the bike and got her all tuned up. She Started on first kick every time no choke. A few days ago when I went riding before I left my friend left the ratchet strap off the side of the truck causing the wheel to catch and flip the bike over completely snapping my front fender off. At first I didn't think anything of it considering nothing major seemed to be broken. But when I went to start it I kicked it a good 10 times before she would fire. I thought that was weird but continued. After stalling the bike it took me 15 minutes of continuous kicking to get the thing to fire. Then it started bogging as the ride went on. The valves are all still in alignment, cams are timed properly, and the cam train is tight. The spark plug works great and the carb jets are clean. Today I tried to start it and it wouldn't even try to fire until I heard the loudest back fire in my life. Sounded life a gun firing right in my ear. Right after the backfire it started in 2 kicks. I know that this is alot of information but does anyone have any ideas? I don't really have anymore money to take it into the shop again. Thanks for the help!
  21. I have never rode a four stroke 250 or 450 before.. i use to race desert a couple years ago and now i want to make the switch to motocross... im honda guy but i also like the 2013 ktm 250 sxf..my last bike was a yamaha 125 which was to small of a motor for me but i weigh 205lbs and im 5'10.. which bike is best to get or maybe even a 450.. idk..
  22. Which one would ya vote for? I'm a Honda guy but I'd vote for the Yamaha. I never see anybody having problems with there yzfs
  23. Hey guys. I really want a 250f race bike. Im 14 and on a kx85 but getting to big. I was going to get a yz125 but my riding buddy just got hurt and cant ride for 4-5 months and i'll be riding rough trails with my dad who is on a quad, and at a track about once every other month. So i no longer want a 2smoker if im going to be going relatively slow. But also at times going fast and jumping, riding is mud ect. Which is why i want a 250f race bike. My price range is gunna be about $2,000. The thing scaring me/holding me back is if something breaks it will be costly. My dad has always worked on my bikes quads and our trucks so he should be able to do a full rebuild if needed. Basically what i want to know is -Is that enough to get me what i want - what bike should i look for - what do i need to check when purchasing - what do i need to do to keep it running strong and prevent things breaking or needing repair - and what is should maintenance cost me per year? Im looking to sell it when im 16 so i can have a downpayment on a truck till i get a job. Thanks guys its much appreciated Ring ding ding ding
  24. MURRIETA, Calif. - KTM announces major revisions to its 2015 model year four-stroke lineup. The company also revealed performance, stability and handling upgrades for its two-strokes and minis. 250 SX-F "The 250 SX-F is once again a World Championship winner in MX2 and adds a prestigious AMA Supercross Lites Championship in 2013 and 2014 to its amazing trophy cabinet," KTM said. "The 2013 season was a great success in racing at all levels around the globe. The performance combination of a powerful and lively engine in a lightweight and agile chassis is sure to make the 250 SX-F the star of the show for yet another year." Engine revisions include a lighter clutch basket and new clutch springs for a more consistent behavior under stress and over time as part of the CSS (coil spring steel) one-piece clutch system. The clutch continues to use a Brembo hydraulic system for light operation and controllable modulation. Within the proven DOHC engine are also new O-rings on the oil pump suction screen for increased durability. For 2015, the 250 SX-F continues to use the Keihin engine management system with EFI and a 44mm throttle body, a quality wire harness, lightweight gearbox, and electric starter. Features include: Compact DOHC engine with two overhead camshafts and DLC-coated followers Titanium valves (intake 32.5mm, exhaust 26.5mm) RPM limit of 14,000 rpm Flow optimized ports Forged box-type piston for a low oscillating mass A crankshaft employing a plain big end bearing for longer service intervals New O-rings on the oil pump suction screen for increased durability A multifunctional counter balance shaft, which drives the water pump and timing chain for reduced vibrations An electric starter as standard Lightweight and compact CSS clutch with eight clutch plates and a hard-wearing steel basket New clutch basket with a weight-saving design New clutch springs for more consistent behavior Lightweight five-speed gearbox for precise and easy shifting, adapted for the 250 SX-F An engine management system for a spontaneous throttle response, and an ability to change characteristics or read engine data with an optional User-Setting-Tool 350 SX-F With the bike's low weight, playful agility and a high-revving engine, "it enjoys all of the very best characteristics in a package suited to amateurs and pros alike," KTM said. For 2015, the 350 features a DOHC engine with lightweight titanium valves and DLC-coated followers for spontaneous power delivery, along with a crankshaft that has been designed to increase service intervals. New O-rings increase durability on the oil pump suction screen. An electric starter is standard. A new lighter clutch basket with new clutch springs compliments the CSS clutch with the Brembo hydraulic system for easy and precise control of a 250-agile bike with the power that can match a 450, KTM said. More specifically, the 350 SX-F features: A DOHC Cylinder head with ultra lightweight titanium valves and DLC-coated followers for a spontaneous power delivery and 450-rivaling maximum power A crankshaft that employs a plain big end bearing and force-fitted bearing shells for longer service intervals New O-rings on the oil pump suction screen for increased durability A multifunctional counter balance shaft, which drives the water pump and timing chain for reduced vibrations Electric starter as standard CSS clutch eight clutch plates and a hard-wearing steel basket A new clutch basket with a weight-saving design Lightweight five-speed gearbox for precise, easy shifting adapted for the 350 SX-F An engine management system for a spontaneous throttle response, and the option to change characteristics or read engine data with a separately purchased User-Setting-Tool 450 SX-F The 450 SX-F is the weapon of choice for the Red Bull KTM Factory Race team in the AMA championships thanks to its compact SOHC engine that delivers explosive but controllable power, combined with an agile and stable chassis, KTM noted. The 450 features: A compact 60hp power pack with a single overhead camshaft and the latest electronic fuel injection A single overhead camshaft controlling four ultra-lightweight titanium valves via "extremely rigid" rocker arms, DLC-coated on the intake side Engine speeds of up to 11500 rpm and a three-layer head gasket for durability under the most extreme conditions Bore of 95mm with a lightweight box-in-box type piston for low engine vibrations A crankshaft that employs a plain big-end bearing and force-fitted bearing shells for longer service intervals A side-mounted counter balance shaft that also drives the water pump Electric starter as standard A DDS clutch with Brembo hydraulic actuation -- a compact design that integrates an internal damping system Lightweight five-speed gearbox for effortless shifting New O-rings on the oil pump suction screen for increased durability An engine management system for a spontaneous throttle response and an option to change characteristics or read engine data with a separately purchased User-Setting-Tool.
