CHANGES IN DETAIL
The machine ridden by Alex cannot be described as a full factory machine. Even if the engine and clutch are heavily modified it is, to all intents and purposes, a stock 300 Sherco which has been finely tuned to meet the needs of the number one French rider. The frame is also seriously reinforced and strengthened; the suspension seems to be reasonably close to standard but the settings are revised.
It is in Torello in the Catalan workshop of Josep Paxau that the machine ridden by Alex was prepared. It is Josep himself who undertakes the majority of changes.
The cylinder head, with its increased compression when compared to standard, is made by Paxau and has a replaceable insert. The cylinder is cleaned up and lowered to increase compression even more – not by using a different base gasket but in the lathe of Paxau. The clutch comes from an enduro machine and is adapted by the factory. It uses a nine-disc pack of smaller diameter rotors in place of the six fitted as standard and a new clutch basket; primary gear and release plate are fitted. This necessitates the machining of a spacer from billet aluminium to raise the cover so that the standard clutch cover can be fitted. A separation device is fitted in the crankcases which allows the oil used in the gearbox and clutch to be separated. This allows different viscosities that are better suited to each situation to be used. Except for trials at high altitude, where an extra flywheel weight is fitted, the ignition system remains unchanged. The CDI is protected by a carbon-fibre cover.
The master cylinders from Braktec are fitted. Headlight surround, ignition cover and side protection are all carbon fibre. Originally from the enduro machine, the clutch fitted by the factory needs a custom spacer to fit the cover. An internal...
