|Modifications compared to previous model||REV-3 250/270Cc – 2008 Technical Modifications
New fork settings. Optimisation of the oil-flow has made the forks more sensitive in absorbing the bumps.
New shockabsorber settings. More stable performance over time, combined with greater reliability.
New Keihin PWK ø 28 mm carburettor: more immediate and lively response at the bottom end, together with a marked improvement in power and acceleration in the middle-to-upper range.
New filter box to optimise the fit with the new Keihin carburettor: improved airflow thanks to a larger diameter sleeve.
New crankcase. New design in the area of the connection between barrel and crankcase has reduced crank chamber volume with a nett increase in smoothness at low revs.
New cylinder head design (on the 250 and the 270cc) ensures more regular carburation when shutting the throttle and provides greater engine torque.
New single-chamber silencer (270cc only): smooths out the power delivery at low engine speeds making it even more linear, and provides a noticeable increase in power and acceleration at the top end.
New main bearings: these ensure greater smoothness and reliability.
New crankshaft oilseal: the reduction in friction has given the engine a cleaner response to the throttle.
New colour-scheme: a brand-new mix of white and fluorescent red.
