KTM’s Mattighofen factory in Austria has invested a huge amount of effort in developing the latest off-road motorcycles for the 2011 season with the clear aim of improving the advantage on loose ground even more.

The star of the KTM model range is the revolutionary motocross innovation, the 350 SX-F.

The current motorsport season is well underway and the KTM factory riders have already claimed a slew of podiums on the latest Made in Austria off-roaders. Now the sports brand from Austria presents the line-up of brand new motorcycles for the model year 2011.

With three high quality and competitive Minicycle variants for the youngest off-road enthusiasts, a total of six uncompromising Motocross motorcycles especially designed for winning races as well as eight versions of Sport Enduros, the Austrian manufacturer presents the perfect line-up for the coming season.

In doing so, KTM once again underlines its leading role in the world of off-road sports activity. The huge amount of depth of development in the new off-road model range extends all the way from the 50cc two-stroke 50 SX right up to the powerful displacement of the Enduro 530 EXC-R.

In between there is a whole range of tailor-made sports machines for every type of off-road riding and for every rider profile, all absolutely true to the KTM ‘Ready to Race’ philosophy. KTM has just the right machine, regardless of whether it’s for the ambitious hobby rider or the ruling world champion.

As well as the huge development effort that the KTM technicians have applied to the entire model range, these new motorcycles still include some very special innovations.

This especially applies to the KTM 350 SX-F, which was first exhibited last autumn. This, the first ever 350cc bike deployed in the World Motocross Championship, has already been mastered by factory riders Antonio Cairoli and his Red Bull KTM team mate Rui Goncalves.

Cairoli not only won the premiere race for the 350 machine, but after multiple GP victories he is also leading the championship standings.

Engine-wise, the 350 has an 88mm bore and 57.5mm stroke and is 349.5cc in capacity, featuring a rev ceiling of 13,000rpm.

The 350 SX-F features electronic fuel injection as well as linkage, as does the 250 SX-F. Meanwhile, the 450 features linkage, but remains carburetted for another year.

The 350 and 250 both have 42mm throttle bodies with two fuel maps to select from as standard.

KTM claims a dry weight of 103.9kg for the 350 SX-F, compared with the 250 SX-F’s 99.9kg and 450 SX-F’s 106.9kg.

As for the two-stroke motocross bikes in the range, they remain with the PDS suspension system that has become to common on KTM in years past.

In addition to the unique engine concept, the Motocross lineup for the 2011 also includes a newly developed frame and chassis components.

While the four-stroke motocross bikes feature new aluminium swingarms for their linkage suspension, the PDS models also have a new revised swingarm to accomodate a longer shock absorber used.

The Enduro models, which have been similarly decorated with world championship titles all also profit from the massive amount of experience gathered by not less than 176 world championship titles. This can be seen both in the feather light two-stroke versions as well as the highly modern and performance powerful four-stroke models.

Of note, KTM has retained the PDS system throughout the Enduro range, believing that it’s the optimum set-up for the off-road terrain.

With significant improvements in a wide range of areas as well as the extensive series equipment, these machines are prepared in the best possible way for the new racing season.

Other notable changes include stronger clutches, zinc-nickel coated spokes and even quieter mufflers for the new year.

The new Motocross, Enduro and Minicycle models will be delivered to KTM dealers from July of this year.
