The revolutionary 125 Max DD2 engine features a 2-speed paddle shift gearbox and a chainless drive system. Steel gear ratios are submerged in oil to creat a wet clutch, and replace the traditional chain and sprocket setup. DD2 specific chassis are manufactured with front brakes and a new unique Rear Tyre Protection system to improve safety. The engine requires no additional blueprinting or engine tuning prior to use. The standard setup for the carburettor covers nearly all operating conditions. For extreme conditions the jetting of the carburettor can be changed in between sessions, and no longer requires the driver to 'tune' whilst racing. The engine has an integrated electric starter with a Touch-And-Go (TAG) ignition. A 6 month manufacturers warranty is included with the engine.
