The 250cc engine has undergone a series of structural changes that make it much more similar to its big sister, the 300cc, in terms of performance. This has been made possible by the use of a crankshaft with a reduced stroke (now the same for both the 250 and 300cc models), which has led to an increase in bore compared to the previous model. A new cylinder head, with a different combustion chamber, and a new cylinder with the appropriate transfers complete the new engine. The result of these changes is a significant increase in torque and linearity of power delivery, without compromising maximum performance, to the benefit of the vehicle’s manageability, also positively impacting handling, centralising the masses and lowering the centre of gravity.
