Here's the brand new POLINI PRE 4 kit for scooter engines with TPR, MALOSSI RC ONE, latest generation POLINI PRE, or even 2 FAST TRT crankcases! This 100cc flanged mount kit is absolutely insane! See for yourself:
-Ø52mm to reach almost 100cc with a 47mm stroke
-100mm connecting rod to reduce engine movement
-Increased Ø14mm piston pin for maximum strength!
-Flanged Mount to maximize clearance for the intake ports and the exhaust port/duct!!!
-Large outlet with 3 screws for exhaust mounting!
-Two-piece cylinder head with studs for excellent cooling
*Attention, only fits on POLINI , TPR, 2FAST or MALOSSI MHR ( RC ONE) FLANGED MOUNT crankcases and in combination with the specific 47mm stroke heavy-weight crankshaft with a 100mm POLINI connecting rod featuring specific dynamic balancing (reference 210.0086)
This cylinder was designed by POLINI 's racing department using the very latest technology and expertise in 2-stroke competition! This allows it to produce absolutely insane power per liter of displacement…
As an option, we offer a Stage 1 preparation. This preparation involves modifying the intake and exhaust ports by increasing the port timing and improving the flow, thus increasing the cylinder's performance. An improved piston and skirt are also included in this modification. Please allow a little extra time for this preparation!
