Four stroke dirt bikes were once overweight and underpowered, but that’s changing fast. Specialist off-road motorcycle manufacturer Husqvarna has disclosed details of a new 250 four-stroke engine it is testing that weighs just 22 kilograms. Though the motor may be small, there has been no significant saving in weight as the new bike, which is likely to be available in limited quantities by the end of the year, comes in at 92 kilos dry – the same as the Yamaha YZ250R and Suzuki RMZ250.

February 18, 2008 Just six weeks after the last minute cancellation of the 2008 event due to threats of terrorist attacks, organizers have announced that the 2009 Dakar will take place in Argentina and Chile. The planned 9000 km loop starting and finishing in Buenos Aires from the 3rd to the 18th of January is the first to be held outside of Africa. As well as the name, organizers aim to retain the spectacular and varied topography, demanding competition and the spirit of the legendary 30 year old race.

January 14, 2008 The development of the four-stroke single cylinder motor is exactly as old as the internal combustion engine, but the needs of the motorcycle are still being understood. Accordingly, Husaberg’s radical new design just might be a significant breakthrough. The engine has been reconfigured to put the crankshaft near the off-roader’s center-of-mass and the KTM-owned company claims a significant improvement in handling because of it.

January 5, 2008 For the first time in its 30-year history, the Dakar Rally has been canceled, the day before it was due to start, due to direct threats launched against the race by terrorist organizations based in the area. It appears the event may be moved to sub-Saharan Africa from 2009 onwards. We commiserate with race fans, organizers and the 550-odd competitors for many of whom this "Everest of off-road" event is a lifelong dream.

October 22, 2007 The 2007 Panasonic World Solar Challenge got underway yesterday with 40 teams from across the globe competing in the 3000 km race from Darwin to Adelaide in Australia. Among the competitors in the Greenfleet Technology Class - a category for internal combustion vehicles promoting an enhanced environmental profile - is the BioBike, a biodiesel-powered motorcycle, constructed by a group of students in Adelaide, Australia, that happily does 96kmh and returns a staggering fuel economy of only 2.2 litres per 100 kilometres. As the design is further refined, BioBike’s creators expect this to drop below the 2 litres per 100km mark (around 107 miles per gallon), and they believe it can be manufactured for around the same cost as a petrol-powered dirtbike.

Four Wheel drive cars have taken over at the top-level of off-road rally racing, but dirt bike racing is still predominantly fought out on single-wheel-drive vehicles that spin up, fishtail and slide wildly across rough terrain. Make no mistake though, the All Wheel Drive (AWD) revolution is coming to the motorcycle world – Yamaha and KTM have done significant work with hydraulic front-wheel-drive systems, and when new ideas like this successful all-mechanical AWD kit from Christini hit the mainstream, dirt bike riding will never be the same again.
