'With the recent double-whammy of financial rating downgrades set to wreak havoc on our economy, however, even bikers are edgy about increased fuel costs,' writes Dries Van der Walt.

KTM unveils lighter, faster Motox SX

2015-05-20 12:00

KTM has unveiled its 2016 SX range - a completely new generation of motocross bikes that are lighter, faster and more agile thanks to a new chassis, revised engines and new AER 48 forks.

The research and development departments in Austria and the US have been working hard to build a strong lineage for the SX and recently celebrated KTM's first 450SX World championship title with Ryan Dungey.

There is also the East 250SX title from Marvin Musquin and two World Motocross championship titles in 2014 so KTM is proud to present the new range which will be available globally from June 2015.


This new SX model, the company says, has state-of-the-art technology, class-leading performance and is the lightest in each class, benchmarks in the motocross world.

90% of parts are new: KTM aimed at better performance and handling for these already world-dominating machines, despite still including the all-important electric starter.

Key improvements include the innovative AER 48 Air Fork developed by WP in collaboration with KTM (US models continue to be fitted with a refined version of the WP 4CS fork), plus a new chassis frame, sub-frame, footpegs, swing arm, linkage and rear shock to provide improved mass centralisation and cut weight (all models except 250 SX).


New smaller and lighter four-stroke engines, plus a new 125cc two-stroke, have been developed to give increased performance. The four-stroke now has launch control , an updated EMS with a faster ECU, and a new throttle body and different riding modes.

The vision is simple: KTM engineers wanted to make their new bikes faster than ever.


Joachim Sauer, KTM's off-road product manager, said: "We're excited to deliver a new generation of SX, developed in collaboration with experts in our R&D department, professional racers, our motorsports department and together with WP. The range is a huge step forward in technology and weight reduction.

"The new AER 48 fork system is an incredibly innovative design; with the new chassis, improved engines and overall refinements, we're confident that riders will feel a great benefit. We also continue to retain specific elements that suit different markets, such as the 4CS fork system for the USA."

The KTM junior range has also received detail updates for the 50 SX, 65 SX and 85 SX, and KTM continues to offer a full range of motorcycles for any kind of riding level for youngsters to progress, as well as adult novice to professional level MXGP and Supercross.
