Motorcycle Previews

The essence of a real dirt bike and supermotard in miniature. This is the nature of the new Husqvarna CR and SM 50, the “mini” that have everything you need to make your debut as a real rider.

Liquid cooled two stroke engines, disc brakes, adjustable suspensions, steel chassis with the same shape as the Husqvarna racing bike, single cylinder engine with dual clutch transmission depending on the driver’s expertise and competitiveness.

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.

The fork is also in CrMo steel and supports a dual piston brake caliper in forged and anodized aluminium.The rear brake disc has a diameter of 140 mm while the front one has a diameter of 160 mm with race replica “daisy” design.

Front safety is guaranteed by a system with Formula radial pump in forged and anodized aluminium with adjustable aluminium lever.

The handlebar, with practical Husqvarna personalized pads, has a diameter of 22 mm.

As regards suspension, the Marzocchi fork has 32 mm diameter piston rods and 185 mm stroke.The Sachs shock absorber has a wheel stroke of 200 mm , adjustable spring preload and Hydraulic rebound.

The front wheel is 12″ the back one is 10″ with aluminium rims, while SM version has a different colour, different sized front wheel (10″) and racing slick tyres.

As regards the engine, both versions are fitted with a liquid cooled two stroke 50 cc engine which supplies 11.2 HP at 10,500 rpm. The speed ratio is single gear with adjustable centrifugal dual clutch transmission:one configuration for learner riders and one for experts.

The carburettor is a 19 mm Orto PHBG.The fuel tank has a capacity of 2.7 litres.

Thanks to the stability offered by the steel framework, the over-dimensioned suspensions and the disc brake system, the CR/SM 50 sets new standards in terms of safety and at the same time represents the starting point for tomorrow’s motocross , enduro and supermoto champions.
