Four years have passed since the beginning of the saga of the revolutionary project called “Pro”, which after a few years of hard work and a constant evolution linked to competition, has restored the confidence of the user, offering a very competitive frame and with the aim of being increasingly reliable.
As usual with the brand, the configuration of both models is the same, with a practically identical engine block, from which they only differ in the dimensions of the cylinder and piston, as well as the cylinder head and carburetion parameters.
Let’s remember that the piston of the ” three hundred” has the virtue of being as light as that of the 280, thus allowing a faster climb of revolutions. All The mechanical innovations incorporated in the 2005 range of Gas Gas have a dual purpose, on the one hand improve the response to low regime, solved with the placement of a new exhaust elbow with greater curvature, and the support of the Kokusan programmable ignition on the 280, being a Ducati also programmable in the case of the “three hundred”.
The second objective is none other than to improve the reliability of one of its most delicate points: the clutch. that in addition to having more evolved discs, it has been equipped with a new clutch pump with a different system from the traditional one, since in this case it works with mineral oil instead of brake fluid, a preventive measure, with which the degradation of the joints is avoided, in the hypothetical case that due to a problem, Brake fluid and engine oil will be mixed.
Finally, in this edition thecrankshaft bearings have a built-in seal, and cooling has been improved by the placement of a new thermal contact.
At the level of part of the cycle, minor changes have been introduced, the same geometries of last year’s chassis are preserved, and all the work has been focused on varying the rear shock absorber setting in search of greater progressivity. Let’s remember that the one in charge of transmitting the necessary rigidity and poise to the front axle, is still an effective Marzocchi fork with 40mm bars.
Finally, a new brake hose made of Teflon has been placed, whose properties allow it to flex less, and manages to send greater pressure from the master cylinder to the brake caliper. Along with these most relevant new features, we have others that improve the dynamic behavior of the bike, such as The rugged handlebar without rebar with variable diameter, assisted by quick-access fasteners with only two screws, and others that affect its aesthetics such as the new decoration and the LED taillight.
