A primary transmission from ATHENA racing! The must of the transmission, in straight gear designed for less power loss and more resistance, a featherweight of the room, reinforced trees ... Really the top of the transmission.
The transmission is extremely important in a good preparation, if your variator and torque controller are at their maximum, your engine level rpm also and the top speed is not enough! Just change your transmission to fully exploit your top speed while obviously losing some acceleration, it will also allow adjustments, a different torque, it will accompany the new settings variator / push spring. We recommend it with a racing crankcase mounted on bearings and a good transmission oil. The primary transmission is the one on which the clutch bell is attached, there is also secondary transmission. 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 running time of about 100km and an oil change after 1000/1300 km.
Attention, on this transmission the teeth are larger than the origin so the ratio is totally changed despite the counting of teeth!
In addition this transmission is in straight teeth instead of being like the origins or top performance (TPR) in leaning teeth. The right toothing allows additional power, much less forcing transmission level, less noise ... We advise in any way a bearing transmission housing that will cause you less trouble and more performance.
There are 3 transmissions primary ATHENA racing competition for motor minarelli scooter
Z (toothing) = 15/50 Semi-long ratio generally +21 (for lightly prepared engines
Z (toothing) = 14/42 Long ratio generally +34 (for good and very well prepared engines)
Z (toothing) = 15/42 Extra long ratio (for the most prepared and efficient engines, top speed guaranteed ...)
Select the desired teeth before purchase.
