Reinforced DOPPLER needle cage Ø12X15X15mm minarelli am6, 103, DERBI, PIAGGIO, PUCH ...

Here is the DOPPLER needle cage, it is a really specific and quite unusual product, in fact DOPPLER is the only manufacturer to still offer needle cages with specific sets. This cage is of very high quality, ultra reinforced and with improved lubrication. Size Ø12mm by Ø15mm by length 15mm.



The clearance must be selected according to the forcing on the piston pin but also according to the engine speed! In general, using the example of a crankshaft bearing, we will take a cage with very low clearance for an engine that takes low speeds because it does not require great freedom! However, on a very high speed engine , if the cage has very little play, at very high speed it may enter into a phenomenon of seizing / overheating and may give way in addition to slightly restricting the engine speed.

-Game from 0 to -2 (low and medium engine speed generally 0 to 8500 rpm maximum)
-Game from -2 to -4 (low and medium engine speed generally 8500 to 10,000 rpm maximum)
-Set from -4 to -6 (low and medium engine speed generally 10,000 and + rpm maximum)

Do not forget to choose the desired game before adding to the cart.The price relates to only one piece!
