2011 Husqvarna CR / SM 50

Posted on by 6

Husqvarna seems to know how important it is for kinds to have the right tool to start their riding days on as they launch two new 50cc models for youngsters – the CR 50 and SM 50. The first a mini cross model and the second a mini motard, both machines are based on the principle that if you have young riders that are hooked on to a manufacturer from the start, they’ll probably stick with it for as long as they ride.

Basically, the 2011 model years are very simple. They both feature the same engine – a 50cc single-cylinder two-stroke developing just under 12 horsepower – and chassis – CrMo frame, Marzocchi fork, Sachs shock absorber and aluminum wheels. These lasts are also the ones that make the difference between the two models.

Overall, the bikes look great with their racy plastics and decals, which is exactly what the little fellows want. Hit the jump for the official press release and specifications.

The line is the same as the Husqvarna dirt bike and Supermotard; with the classic white/red colours for the CR version and white for the SM one, just like the bike that Antoine Meo rides in the Enduro world championship and Adrien Chareyre rides in Supermoto.

The framework is in CrMo steel tubes with rectangular, circular and oval section; the most visible section as it connects the upper beam to the hub.The rear frame is detachable.

So you mentioned four strokes against a two stroke like this one? My question here is what is the initial reaction of the riders between the two? Which one do they really prefer?

That’s a beautiful piece of bike, only to get dirty.

I don’t think this will ever catch on.

That’s a nice dirt bike.

This real dirt bike is quite as responsive for tight off-road riding as a two stroke powered machine. That’s why many riders still prefer them over the heavier four strokes besides its great design and powerful engine.
