Product description

In the late 90's, beveled full circle crankshafts were built into powerful PX motors. Then, along came Andi Wrobel from WORB5, who introduced the first flowed crankshafts, and turned the reed valve market upside down. Flowed crankshafts are the sign of the times in crankshaft development for reed valve shafts. In the past few years there been a lot of movement in this scene - and several interesting versions have been developed, with top performances.

 

In the SERIE PRO line we offer crankshafts, unless otherwise noted, made on the basis of MAZZUCCHELI crankshafts, out of the renowned German tuning master workshop Worb5 - at fair prices. The flowed crankshafts have specially modified streamlined flanges. The crankshaft contour is modified to allow the fuel mix free flow. The fuel mix won't be blocked or create disturbing vortexes by the flange. Flange modification allows more usable fuel volume. Precompression sinks, more fresh fuel can steam in and a higher fill is achieved. This interplay allows a wider speed range and more power. Additionally, flowed crankshafts swing at 12 o'clock, allowing a very quiet run. They are available with either 57 mm or 60 mm stroke. Flowed crankshafts are only usable with a reed valve intake. Use with a disc valve is no longer possible. With a PX ignition, these shafts can be built into the series 1 of the Rally 180/200.

 

If your shooting for 20-25 PS, we recommend the laser welded version. Want more power? Then try the flowed EVO crankshaft or reed valves. Conclusion: Perfect for direct intake reed valve engines. Finally, a simple way to get the necessary intake diameter.

SIP community user "Trapp-Performance" about 46020000: "Great part! Shaft functions super."

 

SIP community user "Scooter and Spareparts" about 46040000: "Used together with reed valve, an absolute Must Have! Modification to flowed crankshaft shows fine balance reduces vibrations when driving. Smooth mmmmh."

 

SIP community user "worb5":  "Used with a 210cc Malossi, English exhaust, 30mm carburetor and of course a reed valve, the flowed crankshaft struts its stuff in all ranges. The motor turns real clean and is simply "sweet". Performance increase of 2 PS guaranteed. 23 PS and more with this combination can be reached."
