Elongated secondary transmission (14/41 or 15/39) ATHENA for scooter minarelli (booster, bw's, nitro, aerox ...)

Here are the secondary transmissions of ATHENA RACING. The transmission is extremely important in a good preparation, if your variator and torque control are at their maximum, your engine revolutions minute also and the top speed is not enough! It is enough to change your transmission in order to exploit your top speed at the bottom while obviously losing some acceleration, it will also allow adjustments, a different couple, it will be necessary to accompany it again settings variator / spring of thrust. For example if you have a very torquey kit like the maxi kit simonini in long race that only reveals its power in low revs, you can in no case achieve good top speeds without extended transmission!

We recommend it with a racing crankcase mounted on bearings and a good transmission oil. The secondary transmission is the one on which the rear wheel is fixed. There is also primary transmission. The ATHENA RACING transmission is of excellent quality and very low price, they are in addition in right toothing in order to gain in performances, to lose in friction ...! Enjoy it. Before purchase, we advise you to observe your primary and secondary transmission to know its teeth and therefore judge on which to take. We recommend a break in about 100km and an oil change after 1000/1300 km. Sometimes it is necessary to mount gables to the press! On request we perform these operations.
