2009 suspension Q?

I am going to upgrade my 2007 450SX-F for a 2009 450SX-F. As I always do, I send the suspension out right away on my bikes. On my current KTM's I have the suspension done @ MX-Tech's head quarters and Jeremy Wilkey personally does them for me. I was riding with Jeremy and he fixed the little problems I had with the suspension, but for some reason the 2008 model feels like I have Factory racing suspension and the 2007 is just OK at best.:thumbsup: He did the same thing (internals/set-up) to both of my bikes, is it because my 2008 is a lighter two-stroke?

Now my question is; how does MX-TECH update there internals for a new model with different suspension or do they just put the same valves in new stuff? I am thinking about having Jeremy just respring (no valves) on my 09 and see how that works.... I am going to ask Jeremy the same question when I see him face to face but I want to walk into this conversation with a little more knowledge from you guys.

Thanks in advance


Here´s something for you : A 2-stroke`s suspension will never feel as good as one on a 4-stroke. 4-stroke power pulses make it "bite" to the ground as opposed to a 2-stroke which likes to skip/bounce off of everything.

The stock 07 WP suspension is fair at best and the 08 WP suspension is 10 times better as it is stiffer. As for your 09 your best bet would be to respring the suspension and fine tune it from there, WP suspension has some of the best pistons on the market, high flow pistons are much better than low flow after market pistons.

Check with davej over at smart performance and have him dial you in. :thumbsup:

      I am purchasing a 2012 KTM 350XCF after wanting one for a year and finally picking one up in December. My question is what are some good things to watch for on this bike as far as initial set up and good Mods to improve bike ? My plan is to add a skid plate, hand guards and muffler with the possibillity of changing the header pipe and a Rekluse EXP would be nice as we ride mostly single track mountain trails with some rocks . Any good thoughts and suggestions would be appretiated

      I got about 6 months on my 350 xcf-w. I ride a lot of tight, rocky,rutty, slippery single track in South west PA. The only things I've added are suspension, bark busters, skid plate and disc protectors. I purchased a trail tech mapping switch but hesitant to add it as I heard the dealer needs to unlock the ECU and am not sure how much of a benefit it will be. I have a Scott steering dampner I'm going to add. I'm also looking at exhaust options for my riding conditions. What do you guys think about the items listed and what suggestions do you have?

      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...
      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.

      Hey guys, i just picked up a used 2012 ktm 450 sxf to be my supermoto race bike next year. the bike seems pretty much stock but there is a connector on the left side of the steering stem that I am 99% sure couldnt be factory. Its a 4 pin connector, 2 wires in, 2 wires out(to the Estart switch on the bar). On the estart side of the connector there is a small jumper wire in the other 2 spots. I have found lots of info on adding the ignition map switch but i can't find anything about this connector or if it was factory. There is a small coil of wire just before the connector and the connectors appearance makes me think it was some aftermarket or home brew ignition map switch. This is a carb US 450sxf.

      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?
