Model progression [edit]
2000 - 2002 [edit]
The manufactory RFS (Racing Four Stroke) KTM 400 EXC won the 1999 Earth Enduro Championship.[1] The 2000 RFS KTM 400 EXC had a right side kickstarter but also had the Due east-start push. KTM took a different approach to the configuration of the motor than most other manufacturers. While others used a 90mm-plus diameter piston with a very brusque stroke of 60mm, the KTM RFS motor used an 89mm x 64mm boiconfiguration which provided more torque at the expense of college RPM's. [2]
2003 [edit]
This was the first twelvemonth of the 450 EXC model. It evolved from the earlier 400 EXC model, with an increased displacement via a longer stroke.
2005-2007 [edit]
These years saw a new frame. Improving the handling without major changes. Rear torso work changed to the single piece design off the SX model. The 2006 450 EXC made 42 hp (31 kW) and 37.5 ft-lbs. torque. [3]
2007 [edit]
This was the commencement year that the 450 EXC was offered in total factory fifty-state street legal trim. The conversion of the previously available model required changes in gearing, frazzle, DOT approved tires and lights and the addition of plough signals, and a horn. Other than these changes the bike was virtually the same as the previously off-road only bike.[4] The United states of america off-route only version of the EXC was replaced past the Xc (Close-ratio manual) and XC-W (wide-ratio transmission) models. 2007 was likewise the last year of the RFS motor. The RFS is very torquey and is known to take very good reliability. In some cases, the fully stock engines last for more than 45k miles. The RFS bike is known to be a skilful dual sport and super motard wheel. The wide ratio 6-speed transmission will run all twenty-four hour period long on the highway. Due to their dual-sport ability, there are larger aftermarket fuel tanks available (11~26L).[v] [6] [1]
2008 - 2009 [edit]
As of 2008 the US version of the 450 EXC continued to be sold in street legal trim but was replaced by the off-route only 450 Ninety or 450 Xc-W in the US market. A new chassis was introduced in 2008 with improvements in intermission and handling. The RFS motor available in 250 cc, 400 cc, 450 cc and 510 cc models between 2000 and 2007 was replaced with the XC4 motor kickoff with the 2008 model year. The XC4 450's accept more power; with a 95 mm x 63.4 mm diameter and stroke producing virtually 51 hp (38 kW).[7] Reliability may have gone down; some people experience top-end problems with the new engine, while others run without incident. 2008 models had oil migration issues(fixed on 2009 models).
2010 - 2012 [edit]

New features include new front Brembo brake caliper, PDS needle design, frame welded to steering caput 10mm lower, reinforced gearbox (i,2,5,6 idler gears), reworked chain adjuster & clamping rails, better tension on timing chain (noise reduction). Oil pump gears, shaft, comprehend and o-ring also updated on 2011 models.
2012 - 2016 [edit]
