MOTOCROSSTIME - NEWS FROM KTM
KTM has enjoyed no fewer than 16 consecutive Rally Dakar victories. Even since 2011, when rules changed and engine sizes were reduced to a maximum of 450cc in an effort to bring other manufacturers into the event, KTM has won every single race. With an all-new bike for 2018, KTM once again takes to the start well-prepared, well-motivated and hoping to take win number 17 …
Following the move of the rally from Africa to South America in 2009, the routes and type of terrains used varied dramatically in the long, flat-out stages of the ‘original’ North African Dakar. In 2011 it was made compulsory for motorcycle engines to not exceed 450cc. This was advertised as ‘levelling the playing field’ for manufacturers in the hope of attracting different brands and with it possibly different winners. At this point, KTM had already won the previous nine rallies. The other factor was safety, by reducing the capacity of the machines, overall speeds would be reduced with the bikes easier to handle during the arduous two-week event.
Going into the 2011 Dakar, KTM had very little time to develop a specialized 450cc machine. Their solution was to fit a carbureted 450cc motocross engine into the chassis of their Dakar-winning 690 RALLY. Although somewhat crude, the bike was a success and took Marc Coma to his third win at the event.
It wasn’t until 2014 that KTM released their first purpose-built 450 RALLY. The bike was designed around a new fuel-injected 450cc engine, the result of which was a far more agile machine. The 450 took Marc Coma to another victory and year-on-year has continued to dominate the Rally Dakar, right up to Sam Sunderland’s win in 2017. Despite their ongoing success, and not wanting to rest on their laurels, KTM already had plans for a newer, slimmer and faster machine.
In development for over two years, the latest incarnation of the KTM 450 RALLY is the most capable yet. At first glance, you can see the bike is slimmer and more maneuverable. Underneath the updated bodywork and fuel tanks are a whole host of other changes that have come together to create a winning machine.
A new frame and swingarm instantly create a narrower bike, a slimmer feeling between the legs for the riders. The bike handles the more technical sections with ease due to the improved design and lighter weight – over 10 kg less than the previous model. The center of gravity on the bike is lower and has been pitched forward, aiding both stability and handling at speed.
The swingarm now sits on its pivot inside the rear of the main chassis, this creates a stiffer rear end and makes the bike less twitchy when ridden hard over the roughest terrain. The rear subframe is fully self-supported, manufactured from carbon, and incorporates one of the fuel tanks. In total, the bike carries approximately 31 liters when fully fueled. Up front, to balance the other changes to the chassis, huge 52 mm WP forks are fitted, another big improvement over the outgoing 48 mm versions.
The bike keeps it standard size wheels – 21-inch up front and 18-inch on the rear, both shod with Michelin tires and mousses. Moto-Master brakes are fitted to slow down the bikes, mounted on the rear is a 240 mm disc while the front carries a massive 300 mm rotor. These provide enough stopping power to bring the bike to a standstill from speeds of over 180 km/h.
With the bike sporting an aggressive-looking black color scheme, Matthias Walkner took the new 450 to the win at the final round of the 2017 FIM Cross-Country Rallies World Championship in Morocco. It was Matthias’ first victory of the season and the Austrian attributed the success to an improved feeling on the new bike.
“The new bike is a massive improvement,” told Matthias. “It feels much safer to ride, although faster at the same time. I think with the input of the younger riders, the bike has progressed a lot and suits the riding style of today. The old bike was a product of the racing as it used to be five or six years ago. Riders like Marc Coma and Jordi Viladoms, who were used to riding the larger capacity machines, perhaps had a different style to how we ride now. A lot of the new, younger riders, coming from a motocross background, prefer the lighter, sleeker feel of the new bike.”
To complement the changes to the chassis, a new 450cc single-cylinder engine has been fitted. Not only providing better peak performance but also improved response. This is achieved by an all-new throttle body and engine management system. The bike is not only faster now but easier to ride at slower speeds when the going gets really tricky and the rider needs that added control.
These combined advantages will really come into their own during an event like the Dakar. With competitors covering close to 9,000 km over 14 stages the race is tough on the rider as well as the machine. The new bike, being easier to ride fast over long distances and less of a handful in the slower, technical sections, will help riders stay fresh and focused.
“I’m so happy riding the new bike,” explains Laia. “It felt so good In Morocco back in October at the OiLibya Rally. It’s not only lighter and faster but it’s more stable and that makes such a difference on the stages. When you hit an unexpected hole or jump the bike always stays straight and that is such a big improvement over the last bike. For me, I know I’m not as strong as some of the other guys in the team so to have a more nimble, the lighter bike is perhaps even more important.”
2016 Dakar winner, Toby Price has had a tough year. The Australian injured his leg during stage four of the 2017 Dakar – pushing hard to make up lost time, Toby came off his bike in a riverbed and fractured the thighbone on his left leg. What followed was a year of recuperation and eventually, further surgery to clean up his left knee and replace the rod in his femur.
Toby has had very little time on any bike during 2017 and has only managed a couple of weeks riding on the new KTM 450 RALLY in its current form. Despite the lack of testing, the former Dakar winner is confident the new 450 can deliver another top result.
“The bike has come on so much over the past 12 months,” said Price. “Even from the outside looking in you can see the new improvements and how it should suit the more technical sections in the rally. Over the long stages, its weight and agility should make things far less fatiguing for the riders – it’s lost maybe 10 kilos during its development and you can definitely feel that when you are riding it. My first full test won’t come until the Dakar itself now, but you only have to look at the results from Morocco to see how strong the bike is and everyone in the team seems to enjoy riding it. I’m really looking forward to seeing what it can do.”
The Rally Dakar starts on January 6, 2018. Close to 200 bikes will set off into the Peruvian desert at the beginning of their 9,000 km journey that will hopefully see them to the finish at the Argentinian city of Cordoba. The KTM team of Sunderland, Walkner, Price, Meo, Sanz and Benavides will all be aiming to take the new KTM 450 RALLY to its maiden win, the 17th in a row for the Austrian manufacturer.
