Long stroke, flowed crankshafts
are the newest update for long stroke shafts. In our SERIE PRO
line, we have modified shafts from the workshops of German tuning master WORB5
, based on MAZZUCCHELLI
The crankwebs have been specially modified and streamlined. The word "gelippt" (=flowed) has established itself as the description of this new hit. Shaft contour design guides the fuel mix through the crank flange instead of hitting it face on when entering. This will keep your fuel flow moving steadily instead of getting blocked or creating unnecessary turbulence. Flange modification allows more usable volume, crankcase compression sinks, more fresh fuel flows in resulting in higher fill. This interaction results in higher speed ranges and increases performance Additionally, shafts are finely balanced, the connecting rod swings at 12 o'clock.
Conclusion: higher performance than normal long stroke crankcases, and less vibrations.
