With just over a month to go until the Moto3 class replaces the 125cc two-strokes, the Grand Prix Commission has finalized the technical regulations governing the Moto3 class - with one or two relatively minor exceptions.
The rules (reproduced in their entirety below) reaffirm that the Moto3 machines must be a prototype chassis containing a 250cc normally-aspirated four-stroke single, with a maximum bore of 81mm, a spec Dell'Orto ECU, a rev limit of 14,000 rpm, and with no variable valve timing or variable inlet or exhaust tract length, including the use of EXUP-style valves in the exhaust. Throttles must be cable-operated directly by the rider, with no electronics to assist with throttle butterfly opening, though electronic assistance is allowed for helping with engine braking. Only standard gearboxes will be allowed (i.e. no seamless shift systems), and only two ratios per gear are allowed, to be selected at the start of the season.
