KTM has revealed its 2018 motocross line-up which will feature revisions to its adult bikes alongside a brand new 85cc two-stroke youth machine.

The 2018 KTM 85SX has a new motor with more power and weighs 0.69kg less than the current bike, a new, lighter steel frame and subframe, WP AER 43 air forks and a new WP Xplor PDS shock for its linkless rear suspension.

All bikes get revised suspension settings in the WP AER 48 forks, along with a factory-style orange frame and new graphics.

The 125 and 150 two-strokes now have new aluminium head stays and a new CDI said to improve starting. The bikes will start to arrive in the UK for sale later this month.

KTM’s adult range was all-new in 2016, apart from the 250SX which was new for 2017. KTM often works to a three-year production cycle so it’s likely there will be totally revamped models for 2019.

The official information, released by KTM USA, says:

With its 2-stroke and 4-stroke machines, from the KTM 50 SX to the KTM 450 SX-F ultimate powerhouse, KTM offers high quality serial equipment in all of its motocross range. As developed for its factory racing teams, which have won numerous races and championships, including last year’s AMA 450 Supercross title with Ryan Dungey, as well as the FIM MX2 World Championship with Jeffrey Herlings, these KTM serial machines are renowned for being READY TO RACE right out of the crate.

For model year 2018 KTM introduces a brand new KTM 85 SX for junior riders that are cutting their teeth in the schoolboy ranks. With the serious competitor in mind, this machine has a new engine that is 0.69 kg lighter than the previous model, with improved power and rideability throughout the complete RPM range. In addition, the KTM 85 SX receives a lighter chassis with a revised chromium molybdenum steel frame as crafted by WP Performance Systems, as well as a lighter subframe. This READY TO RACE Mini, which joins the KTM 50 SX and KTM 65 SX in KTM’s line-up of premium junior equipment, is fitted with high-quality Formula brakes, WP AER 43 forks and a specifically developed WP Xplor progressive damping system (PDS) shock absorber, which provides excellent sensitivity and outstanding bottoming resistance with full adjustability.

In the adult range the KTM 125 SX and KTM 150 SX now feature new aluminum head stays, as well as a new CDI control unit for improved starting behaviors. As with all of KTM serial equipment, the 4-stroke range, including the KTM 250 SX-F, KTM 350 SX-F and KTM 450 SX-F, boasts high-quality, class-leading components from the all-important E-starter, to the WP suspension, traction control and map selection, and much more to compliment the super lightweight, yet powerful championship winning engines.

In addition, the complete model year 2018 SX range including both 2-stroke and 4-stroke machines feature revised suspension settings in the WP AER 48 forks, along with a factory-looking orange frame plus, brand new graphics to finish the look.

“Once again our engineers in the KTM R&D department in Mattighofen, Austria have refined the very successful SX range. The adult bikes showcase a sportier look just like the factory bikes with their orange frames, while we’ve also spent some time working on the Mini range for the developing juniors and stars of tomorrow. In particular the incredibly successful KTM 85 SX has had a real overhaul with its new chassis, engine and suspension, which have been re-designed for improved rideability whatever the level of rider. As always these bikes are READY TO RACE right out of the crate and we look forward to releasing the SX model year 2018 range,” said Joachim Sauer, Product Marketing Offroad.

Model year 2018 KTM SX models will be arriving in dealers from May onwards. For detailed pricing information and availability, please contact your local KTM subsidiary or importer.
