| Rotary slide | Bottom connecting rod eye with chamfer for crankshafts with rotary slide |
| Machining | High-strength forged, precision CNC finishing |
Forged bgm PRO connecting rod with 128mm length and fine CNC finishing. The extended connecting rod length improves the connecting rod ratio, reduces vibrations and reduces the tilting moment of the piston at the reversal points. Designed for setups with cylinders such as Quattrini M232/M244 and VMC Explorer 244. Depending on the concept, a suitable spacer is required on the cylinder base. Suitable for crankshafts with Ø20mm crankpins.

Many M232/M244 and Explorer 244 concepts benefit from 128mm connecting rod length. Spacer thickness, crushing edge and desired timing are relevant for planning. The overall length is usually compensated for by a spacer at the cylinder base.
Apart from the connecting rod length and lower crankpin, the geometry is based on standard PX200 dimensions. This makes it easier to combine with proven components.
Which cylinders fit particularly well?
Quattrini M232 and M244 as well as VMC Explorer 244.
Spacers required?
Yes, a spacer is usually required at the cylinder base. Thickness depends on cylinder and target setup.
Does it only fit PX200?
Designed for PX200 crankshafts with Ø20mm journals.
Ø15mm piston pin possible?
Yes, with special bearing 7672564.
Conclusion: Robust forged connecting rod for converting or building new crankshafts in setups with Quattrini M232/M244 or VMC Explorer 244.
