Crankshaft -KINGWELLE Brutus I (connecting rod Primatist) M200 (for Quattrini engine case C200, cheeks=Ø92mm, balance factor 50%) - full cheek 60mm stroke, 118mm connecting rod- Vespa PK125 XL2, PK125 ETS (Ø 24mm cone)
Description
Crankshaft KINGWELLE - Highend 'made in Germany' - only the best is good enough
QUALITY³
'Kingwelle' crankshafts are among the very best available on the market. Manufactured piece by piece with absolute precision on high-end machinery by the racing enthusiastic Cramer brothers. The extremely powerful engines, as they are used by the two personally in Vespa acceleration races, require absolute top material for rear wheel performance above 70 HP. As their highest maxim, they only sell what meets their own extremely high standards. So the best is just good enough for them. This gives you the reassuring security to be always on the safe side with a Kingwelle and to always get 150 percent quality.
Professional racing crankshaft
Made in Germany from high-strength and tempered material

Available with connecting rod lengths:
116mm (Mazzuchelli)
118mm (Primatist)
Maximum torsion resistance
Ideal balance factor of 50% with Quattrini M200 piston (or similar)
Fine thread M12x1mm
Extra large crank webs (crankcase must be spindled out on both sides)
WHICH HUB?
The BRUTUS type crankshafts are available with 60mm stroke (+3.5mm stroke compared to M200 series). The bigger the stroke the bigger the achievable displacement. So a Quattrini M200 with a crankshaft with 60mm stroke becomes a cylinder with 211ccm.Much more important than the increase in displacement, however, is the possibility of adapting the control angle of the cylinder to its needs through the larger stroke. The power band can thus be significantly changed and increased.
FEATURES OF THE SF BRUTUS KINGSHAFTS
THREAD
A massive plus point is the use of a fine thread (M12x1.00).
The combination of good material and the resulting possibility to use a fine thread increase the contact pressure twice:
the fine thread has a significantly higher contact pressure and self-locking for the same tightening torque
thanks to the excellent crankshaft material and the subsequent heat treatment, a high tightening torque is possible despite the fine thread (recommendation: Kingwelle 60-80Nm).
This means that the clutch and pole wheel are much tighter than with the conventional threads provided by Quattrini (M12x1.25).
PLEUEL
Kingwelle uses only high quality connecting rods. It depends on the desired connecting rod size from which manufacturer these are available. The only decisive factor for Kingwelle is that they can cope with the enormously high loads of today's engine concepts. This is tested by them in advance and only 100 percent top material is selected and used.
CONCLUSION
All constructive improvements resulted in one of the most powerful crankshafts for M200 based engines. Last but not least, the Kingshaft has a very smooth running due to its precise assembly and alignment. The shafts are aligned manually to approx. 1/100mm concentricity. Thus they achieve a dreamlike running smoothness and make it possible to reach the full engine power and to transfer this to the road.
PLEASE NOTE
The stroke and, if necessary, the longer connecting rod must be compensated by appropriate spacers on the cylinder head or cylinder base. This also sets the control angles of the cylinder that are ideally suited to the engine concept.
ATTENTION
This is a tuning product! The durability of the engine is strongly influenced by it, the risks cannot be estimated. Property damage and damage to life and limb as well as damage to third parties are to be feared. The installation and operation of a tuned engine is the sole legal responsibility of the buyer of the tuning products in full!
