Description


The bgm PRO Racing Shaft with 54 mm stroke is the maximum for racing or ambitious road tuning.
The cheek diameter has been enlarged in contrast to a normal shaft to achieve the necessary higher overlap at the crankpin despite the increased stroke and thus additional torsional resistance to

. This minimises the risk of twisted cheeks and welding with the usual disadvantages is not necessary.

With virgin housings, the housing must therefore be spindled to 88 mm

.

A huge advantage is the high quality 105 mm long connecting rod, with cleanly executed lubrication holes and now 5 mm thick. This is eight millimetres longer than the standard connecting rod of the 125 series. The advantages of the longer connecting rod are a more favourable deflection angle and the resulting lower friction of the piston in the raceway.

This increases the performance and results in a lower pre-compression, which works great especially with the new reso systems such as the fire magic of the company Ludwig und Scherer. M7 studs (BGM 0290) must be used. All this is included in the kit (7673184).

The shaft is operated with the standard bearing of the ETS.

- Non-rotating,Stable cheeks

- High-quality 105mm long connecting rod with 5mm thickness

- Good lubrication holes and slots

- Reasonably dimensioned thrust washers

- Designed for the high-speed ETS Lima bearing

-lower precompression

- Favourable deflection angle at the connecting rod bearing
