Other specifications

Modifications compared to previous model Technical Modifications 2008: New fork settings. Optimisation of the oil-flow has made the forks more sensitive in absorbing the bumps as well as more reactive on the rebound, to facilitate acrobatic manoeuvres or simple movements of the front wheel. New dedicated shockabsorber settings to suit the cycle parts and the power delivery of the 4-stroke engine. New electric fuel tap: more practical, results in better mechanical accessibility and increased reliability. New hot start knob integrated into the carburettor union: immediate and easy accessibility improves practicality in starting the engine from hot. It is also less cumbersome and less vulnerable to crash damage than the earlier lever on the handlebar. New pressure-cast casings: these provide optimised design at the bottom end of the bike, to make a better match with the stoneguard rubber and casing. New outer clutch cover with five-bolt fixing for a better seal. New position for the oil filler plug: improved access to facilitate maintenance operations. New design for the clutch cover with the addition of lateral grooves to facilitate removal of the clutch: greater practicality during maintenance. New exhaust pipe with reduced metal thickness (1 mm): greater performance under acceleration together with a substantial weight reduction (-150 grams). Euro3 homologation. New colour-scheme: a brand-new mix of black and fluorescent red.
