Husqvarna has decided to present two limited-edition racing, the SM 450RR and the SM 530RR to celebrate this success at the 2008 Supermoto World Championships when Adrien Chareyre and his Husqvarna SMR 530 won two world titles.

Riders could have experience riding the same racing components like Adrien Chareyre, Gerald Delepine and Thomas Chareyre’s machine on the track.

2009 Husqvarna SM450RR will have a completely new look with a new supermotard front mudguard and a special colour scheme to highlight their competitive, winning nature. The saddle has been specially designed to offer the rider better when accelerating.

2009 Husqvarna SM450RR’s engine, the more powerful “race” engine is mated to a six-speed box derived from motocross versions as are the STM slipper clutch, the electric starter, the 41 mm Keihin carburettor and the special cams and pistons. In collaboration with Arrow, Husqvarna engineers designed a tailor-made exhaust system for the SM530 RR. Like that on the SM 450 RR, it is made from titanium and features twin silencers. The heat shield is also made from titanium.

Husqvarna SM 450 RR and SM 530 RR feature “Wave” discs with a 310mm disc up front for a better compromise between adjustability and stopping power. As regards suspension - up front there are 50 mm Marzocchi forks with a sealed cartridge unit and anodised black fork bottoms while, at the rear, there is a Sachs racing aluminium-bodied shock absorber and the frame is painted black.

The twin-coloured anodised aluminium filler cap is new as are the anodised Ergal racing handlebar clamps. These are one-piece items bearing the legendary Husqvarna name. The motorcycles come supplied with spare sprockets and crown wheels and a set of steering rake sockets as well as a racing type side stand, racing brake and clutch levers and hand guards The machines are not homologated for use on the road and can only be ridden on a track. They will be available from early December through orders made through the Husqvarna sales network.
