Racing crankshafts are a simple and effective tuning upgrade for every disc slide valve engine. A racing crankshaft gets higher rpm_s, your engine will be agile and have more pep. Better acceleration and higher top speeds are the result.
A racing crankshaft has noticeably longer intake timing in comparison to an original crankshaft. Your fuel charge will also be greater. The crankwebs are streamlined and polished, turbulence and flow blocks are reduced. The connecting rod is partially a polished edged connecting rod, the lower connecting rod bearing is a silver bearing. All crankshafts are delivered with upper connecting rod bearings.
High quality racing crankshafts from Italian manufacturer MAZZUCCHELLI have minimal production tolerances, lowered bearing play and a very good price/performance ratio. High speeds and absolute durability are a guarantee. We are offering a supplementary finely balanced version. In this version, the connecting rod is balanced at 12 o'clock. This shaft operates impressively quiet.

The racing crankshafts from TAMENI have very good moulding compound, resulting in stable high rpm's and highest durability guaranteed.
PINASCO racing crankshafts have streamlined polished flanges. The connecting rod is high quality polished workmanship and comes with PINASCO lettering and silver bearing. For optimal lubrication, it's equipped with additional lubrication bores/slits. In addition PINASCO also now have a new sport orientated long stroke (62mm)/racing crankshaft available. It features more extreme inlet-port timing, a gas-flowed surface profile, tungsten balancing weights and innovative PTFE inserts for a higher primary compression. This crankshaft is ideal for both touring or race orientated motor set ups!

Conclusion: This doesn't have to be combined with a tuning cylinder; you'll get a noticeable performance plus when used with your original cylinder.
