KTM 450 SX-F 2013

I would be giving you mud if I was to say this was my new ride for 2013.  But the year is still young and opportunity often comes knocking at your door in many ways.

Ultimately test riding the KTM 450 SX-F in New Zealand may be a great opportunity at Farm Jam and on tour.  I ride KTM and know the mechanics of the machine really well.

I generally ride the 250 due to weight and price, however the sponsors are heading the boys ultimateley towards the 450. There is a skill required in FMX to cross between the two.  Riders can be challenged by this for a number of reasons.  Eventually, when I hit some dirt and fly some ramps on a test model of the KTM 450 SX-F, I will give you a further review.  I am yet to stradle the saddle.

  At the moment I can only give you the low down about what we have discovered in our research and investigation.

Through some clever engineering and knowledge by Roger Decoster and his development team, the KTM 450 SX-F really seems to be the most improved for 2013.  There are some significant improvements with a lighter, more powerful and controlable engine that features injection technology, considered ground breaking. Frame, bodywork and suspension have all been improved and is setting a new benchmark in handling, manoeuvrability and performance for KTM.

he engine is reported to be smooth but strong and a new single overhead cam shaft is designed to have less mass at the top of the engine. This is designed to result in less weight in the engine fighting against the rider when changing directions or turning.  It appears to have loads of power and reported to be as smooth or bark as loud as you need, when you need it.

Initial stroke and mid stroke throttle preferences do depend on the rider. The tweak of the throttle in conjunction with the new injection will obviously give you the response that you need.

The chassis is different and designed to give the rider more control over the direction of the bike.  From my experience, previous models had issues with the bike driving you.  This is due to the trail of the real wheel friction chattering into the turn.  With the improvements, it is reported that the rear stays planted to the ground and the front wheel steers into tight ruts with ease.

  The suspension is better, but I have heard it is still a little harsh mid stroke for some.  Heavier riders may find this good, although light weights may find the suspension hard and a bashing on the hands. Customisation is possible.

They have also started using European Pankl connecting rods. The rod now contains a plain bearing that can last in excess of 100 hours instead of a roller bearing which has less duty.

KTM is a European company with origins from Austria.  Being Euro they always find the best parts.  This has been costly in the past, although KTM are now pretty level with the Japanese brands regarding reliability.

 Apparently not much spend is required to replace parts, due to reliability. But if purchasing I would want to check the list.

The basket is manufactured from steel and machined to fit.  It has damping rubbers to absorb some of the harshness out of the vibrations from the engine. The diaphram clutch now uses a diaphram spring instead of a six coil spring.

  The diaphram spring is designed to keep a constant even load on the clutch pack.  You can also choose three different tension settings for the clutch plate.

The KTM SX-F only uses an electric start.  This can be identified as a risk if not in working order. In this case you need to make sure your battery is charged and in reliable condition when riding.  I am sure there is more to say about this unit.

  I founds some videos and specifications if your interested in having a closer look.
