First look: 2008 four-stroke Husqvarna motocross and enduro range

Husqvarna has just launched the entire 2008 motocross and enduro motorcycle range. There are nine new models with four-stroke and two-stroke engines – here’s a breakdown of the four-stroke updates.

The four-stroke Husqvarna TE 250, Husqvarna TE 450 and Husqvarna TE 510 enduro range and the Husqvarna TC 250, Husqvarna TC 450 and Husqvarna TC 510 models get a new frame which is lighter, lower and narrower for better control.

Each motorcycle is claimed 4kg lighter, and to improve both sitting and standing positions the footpegs are 15mm further forward, and the frame guards are tucked in tighter to make the motorcycle narrower between the rider’s legs.

Overall geometry has been tweaked and weight distribution changed, though Husqvarna hasn’t revealed the specific changes.

The four-stroke motorcycles have all-new rear suspension systems and new swing arms, which Husqvarna say puts 40% less loading on the frame. The shock absorbers are fitted with larger pistons for more oil flow and more adjustability. The forks are now Marzocchi 50mm fully-adjustable items on the TC motocrossers.

The sub frame is new, and the revised frame allows a straight inlet duct for better airflow into the airbox. New handlebar clamps grip tough Tommaselli ‘Fat Bars’.

The 250, 450 and 510 engines will all be fitted with Mikuni fuel injectors in the Enduro models – the motocross range will continue with carburettors. Kickstart mechanisms are revised on all models and starting should be improved with a new decompression system. The TE enduro motorcycles have an additional electric start.

Reliability is claimed to be improved through a new valve lifting system, chain tensioner and clutch basket. The engines are now finished with matt black crank cases, aluminium barrel and cylinder head, and a Ferrari-style red valve cover. The gearbox has received detail changes to improve shifting, and the clutch is claimed be more reliable with better operation.

The motocrossers have a full titanium exhaust system – the enduro bikes have a steel system with more silencing.
