Improvements in the Speed Selector of Motorcycles (ES2173777A1)

It is characterized in that the shaft (2) is disposed in selector core incorporation desmodromic through the drum (3), both coaxially coincident, so that the whole occupies a minimal space in assembly.

The shaft (2) of the selector and the desmodromic drum (3) provided one swivel solution, by way of one ratchet, with a rocker (6) associated with the shaft (2) undergoing a rocking push radially outward and by determining the desmodromic drum (3) with an inner contour provided with concavities (9) for which are likely to engage and disengage the rocker.
